Vickers VC10



The Vickers VC10 is a long-range British airliner designed and built by Vickers-Armstrongs (Aircraft) Ltd, and first flown at Brooklands, Surrey, in 1962. The airliner was designed to operate on long-distance routes with a high subsonic speed and also be capable of hot and high operations from African airports. The initial concept of the VC10 was to provide a jet-powered airliner that could comfortably make use of the shorter runways commonly in use at the time. The performance of the VC10 was such that it achieved the fastest crossing of the Atlantic (London to New York) by a jet airliner, a record still held to date for a sub-sonic airliner; only the supersonic Concorde was faster. 

The 50th anniversary of the first flight of the prototype VC10, G-ARTA, was celebrated with a special 'VC10 Retrospective' Symposium and the official opening of a new VC10 exhibition at Brooklands Museum on 29 June 2012.
The VC10 is often compared to the larger Soviet Ilyushin Il-62, both aircraft having a rear-engined quad layout, the two types being the only airliners with such a configuration. As of March 2013 4 VC10s remain in service as aerial refuelling aircraft with the Royal Air Force however these are scheduled to be retired in September 2013.

Design and development

Origins
Britain's aviation industry had been government-managed in practice, particularly during the Second World War. Design and manufacture of transport aircraft had been abandoned in order to concentrate on production of combat aircraft with Britain's transport aircraft needs being met by the provision of US aircraft through Lend-Lease. In 1943 the Brabazon Committee introduced command economy-style principles into the industry, 
specifying a number of different types of airliners that would be required for the post-War years, though it assumed that US dominance in transport aircraft would translate into leadership in long range airliners and conceded in principle that the industry might have to cede the long-range market to US makers.During the 1950s the government required the industry to consolidate: in consequence only two engine makers were left by 1959: Rolls-Royce and Bristol Siddeley.
 In 1960, the British Aircraft Corporation (BAC) encompassed Vickers, Bristol, and English Electric's aviation interests, Hawker Siddeley built on de Havilland's heavy aircraft experience, and Westland consolidated helicopter manufacture. In 1977 BAC and Hawker Siddeley (by then also including Avro) were nationalised and merged to form British Aerospace.

BOAC background

The British government controlled route-licensing for private airlines and also oversaw the newly established publicly owned British Overseas Airways Corporation (BOAC) long-range and British European Airways (BEA) short and medium-range airlines. These were subject to public interest as well as commercial advantage, thus BOAC served British Empire destinations across Southern Asia and Africa, many of them in remote and less-developed areas, commercially unattractive but politically, strategically and socially important.
As had been the case for its interwar predecessor, Imperial Airways, BOAC was expected to operate British-designed and built, or at least British-powered, aircraft, their procurement bills being met by the Ministry of Supply. Several aircraft commissioned had been unsafe (Comet I), delayed (Britannia) or uncompetitively priced (Canadair North Star, Hermes) - or had all of these defects combined.[citation needed] This had strained relations between airlines and aircraft makers

The VC10 concept

The VC10 was a new design but used some production ideas and techniques, as well as the Conway engines, developed for the V.1000 and VC7. It had a generous wing equipped with wide chord Fowler flaps and full span leading edge slats for good take-off and climb performance and its rear engines gave an efficient clean wing and reduced cabin noise. The engines were also further from the runway surface than an underwing design - of 
importance considering the nature of the African runways. Technology from the V.1000 and later Vanguard programmes included structural parts milled from solid blocks rather than assembled from sheet metal. The entire airframe was to be coated against corrosion. 
Planned flight-deck technology was extremely advanced, with a quadruplicated automatic flight control system (a "super autopilot") intended to enable fully automatic zero-visibility landings. Capacity was up to 135 passengers in a two-class configuration. 
Vickers designer Sir George Edwards is said to have stated that this plane was the sole viable option unless he were to reinvent the 707 and, despite misgivings on operating cost, BOAC ordered 25 aircraft.
Vickers calculated that it would need to sell 80 VC10s at about £1.75 million each to break even so, apart from BOAC's 25 another 55 remained to be sold. Vickers offered a smaller version (the VC11) to BEA for routes like those to Athens and Beirut but this was rejected in favour of the Hawker Siddeley Trident.

Production and order problems

Vickers revamped its production plans to try to achieve break-even point with 35 sales at £1.5 million each, re-using jigs from the Vickers Vanguard. On 14 January 1958 BOAC increased its order to 35, with options for a further 20 aircraft,[3] all with smaller 109-seat interiors and more first-class seating so, as orders from BOAC alone now allowed break-even, the use of the Vanguard jigs was abandoned and new production jigs made.
BOAC had calculated that the Boeing 707 cost £4.10 per passenger-mile while the VC10 would cost £4.24.[dubious – discuss] This information was leaked, reputedly with the loss of several foreign orders.[citation needed] The difference brought calls to cancel the order in favour of the 707. The VC10 was rescued by the British government and in order to offer more economy Vickers began work on the Super 200 development of the VC10 with more powerful Conway engines and a 28 feet (8.1 m) longer fuselage offering up to 212 seats, 23 more than the Boeing 707-320 series.
By January 1960 Vickers was experiencing financial difficulties and was concerned that it would not be able to deliver the 35 VC10s without making a loss. It offered to sell ten Super 200s to BOAC at £2.7 million each only to find that BOAC was unconvinced it had a role for the already ordered 35 VC10s and doubted the airline's ability to fill all 200 seats. The government intervened again on Vickers' behalf with an order for Super 200s, placed on 23 June 1960. The Super 200 extension was cut down to 13 ft (3.9 m) for the final Super VC10 (Type 1150), the original design retrospectively becoming the Standard VC10 (Type 1100).
In accordance with its contracts with Vickers, in May 1961 BOAC amended its order to 15 Standard and 35 Super VC10s, eight of the Supers having a new combi configuration with a large cargo door and stronger floor: in December the order was reduced again to 12 Standards. By the time deliveries were ready to begin in 1964 airline growth had slowed and BOAC wanted to cut its order to seven Supers. In May the government intervened, 
placing an order for VC10s to operate as military transports to absorb over-production.
This lengthy, well-publicised trouble did much to erode market confidence in the type.BOAC chairman Gerald d'Erlanger and managing director Sir Basil Smallpeice resigned, defending the opinion that the national airline was a profit-making company, not a sponsor of indigenous aircraft designs (Smallpeice was later an ardent supporter of the Margaret Thatcher premiership). BOAC's incoming chairman Sir Giles Guthrie was also 
anti-VC10: he proposed that the Vickers programme should be shelved in favour of more 707 orders.age, which raised emergency escape concerns, and the design failed to attract orders.

Development and production

The prototype Standard, G-ARTA, rolled out of the Weybridge factory on 15 April 1962. On 29 June, after two months of ground, engine and taxi tests, it was first flown by Vickers' chief test pilot G R 'Jock' Bryce, co-pilot Brian Trubshaw and flight engineer Bill Cairns from Brooklands to Wisley for further testing.[5] By the end of the year two more had been flown to Wisley. A serious problem with drag appeared: to cure it Küchemann wingtips and "beaver tail" engine nacelle fairings were added and tested. Along with a reworking of the basal rudder segment (its scythe shape replaced by an angular design with an endplate for greater control effectiveness), this lengthened testing. The certification programme included visits to Nairobi, Khartoum, Rome, Kano, Aden, Salisbury(Harare) and Beirut. A VC10 flew across the Atlantic to Montreal on 8 February 1964.
By this point seven of the original 12 Standards were complete and the production line was preparing for the Supers. A Certificate of Airworthiness was awarded on 23 April 1964 and the plane was introduced to regular passenger service between London and Lagos on 29 April.[6] By the end of 1964 all the production requirements had been fulfilled, Vickers (by this point part of the BAC) retaining the prototype.
The first Super VC10 was first flown from Brooklands on 7 May 1964. Although the Super was ostensibly a minor development of the Standard with an extra fuel-tank in the fin, testing was prolonged by the need to move each engine pair 11 in (27 cm) outboard as well as up and giving them a 3 degree twist. This major redesign was needed to resolve tailplane buffeting and fatigue issues due to thrust reverser operation. The two inboard engines could have thrust reversers installed at last, matching the 707. (Military VC10s also had this engine arrangement.) There was 3.0% more wing area with the leading edge extension reducing aspect ratio and wing root thickness/chord ratios. These changes improved low speed lift and reduced high Mach drag respectively.
Later VC10 design developments included testing a large main-deck freight-door and fitting new wing leading edges featuring a part-drooped, four-per-cent chord extension over the inboard two thirds and a drooped, extended-chord wing-tip that allowed more economical high-altitude flying. (This mimicked the 1961 aerodynamics of the similar-looking but significantly different Il-62.) Further developments proposed included freighter versions, one with front-loading like the C-124 Globemaster II. Efforts focused on getting a BOAC order for a 250-seat "VC10 Superb",[8] a move away from the VC10's initial MRE role into the area targeted by the DC-8 Super Sixties. The VC10 would have needed an entirely new double-deck fuselage, which raised emergency escape concerns, and the design failed to attract orders.

Commercial service and sales

A total of 12 Type 1101 VC10 were purchased in 1964-65, followed by 17 Type 1151 Super VC10 in 1965-69. The VC10 became an immensely popular aircraft in the BOAC fleet, both with passengers and crew, being particularly praised for its comfort and low cabin noise level. BOAC (and later British Airways) obtained higher load factors with the VC10 than with the 707 or indeed any other aircraft of its fleets.[9] Operational experience soon resulted in the deletion of the inboard thrust-reversers due to continued 
tailplane buffeting despite the engine repositioning. Two BOAC Super VC10s were lost in terrorist hijackings in 1968 and 1970.
Ghana Airways ordered three VC10s in January 1961: two to be fitted with a cargo door, known as Type 1102s. The first was delivered in November 1964 and the second in May 1965: the third was cancelled. Ghana Airways leased one aircraft to Tayaran Assharq Alawsat (Middle East Airlines; MEA), destroyed at Beirut during an Israeli raid in December 1968. The other was retired from service in 1980. MEA also leased the prototype aircraft that Vickers had kept until 1965, leased from Freddie (later Sir) Laker's charter airline.
British United Airways (BUA) ordered two combi versions (Type 1103) in 1964, receiving them in October that year. When BOAC ceased VC10 operations to South America BUA took them over, purchasing Ghana Airways' cancelled third aircraft in July 1965 (a Type 1103). The prototype aircraft was purchased from Vickers/BAC and converted from Type 1101 to Type 1109 in 1968. It was initially leased to Middle East Airlines but returned to British Caledonian (as BUA had become) in 1969. The prototype was damaged beyond economical repair in a landing accident at Gatwick in 1972 and the others were sold in 1973-74. One saw further service with Air Malawi, being retired in 1979, and another was sold to the Sultan of Oman as VIP transport and was preserved at Brooklands upon its retirement in 1987. One aircraft went to the Royal Aircraft Establishment for equipment 
tests and was retired in 1980.
Nigeria Airways had planned to buy two VC10s but had to cancel the order for financial reasons; it leased a BOAC aircraft from 1969, but it was destroyed in a landing accident at Lagos in November that year.
The final VC10 was the one of five Type 1154 Super VC10 built for East African Airways between 1966 and 1970. Of these, one was destroyed in a take-off accident at Addis Ababa in 1972, and the other four were retired in 1977 and returned to BAC, subsequently being purchased by the RAF. After the last aircraft was delivered in February 1970, the production line closed, 54 airframes having been built. The 707 and Douglas DC-8, with their superior operating economics, had encouraged many of the world's smaller airports to extend their runways, thus eliminating the VC10's main 
advantage.
Marketing overtures were made elsewhere, particularly in Mexico, Argentina, Lebanon, Thailand, Czechoslovakia, and Romania, often fronted by British politicians. In reminiscences some of these figures have claimed that BOAC staff actively sabotaged VC10 marketing by leaking confidential documents relating to the type's fuel consumption.[citation needed]) The final serious enquiry for VC10s came from Chinese state airline Zhōngguó Mínyòng (CAAC) in 1971. It was confirmed in 1972 but by then 
the production equipment had been broken up. Czechoslovakia, Romania and China eventually purchased the Ilyushin Il-62 (for Czech Airlines, TAROM and CAAC, respectively).
BOAC's successor British Airways began retiring its Super VC10s from Atlantic flights in 1974, mainly due to the 1973 oil crisis, and using them to displace standard VC10s. Ten of the eleven surviving standard models were retired in 1974-75. Of these, five were leased to Tayaran AlKhalij (Gulf Air) until 1977-78 then purchased by the RAF. One was leased to the Government of Qatar for VIP transport until 1981 when it was purchased by the RAF as an instructional airframe. Another went to the Government of the United Arab Emirates for similar purposes until retirement in 1981 and preservation at Hermeskeil, Germany. The other three were traded in to Boeing as part payment on new aircraft and Boeing scrapped them at Heathrow. The last standard VC10 in British Airways service, G-ARVM, was retained as a stand-by for the Super VC10 fleet until 1979. It was then preserved at RAF Cosford as part of the British Airways Museum collection. Its condition deteriorated (BA having withdrawn funding of the collection) and it was reduced to a fuselage in 2006 before being moved to the Brooklands Museum in order to create space for the new National Cold War Exhibition.
Retirement of the BA Super VC10 fleet began in April 1980 with use continuing on less-travelled routes until 1981. After failing to sell them to other operators British Airways sold 14 of the 15 survivors to the RAF in May that year (one went for preservation at Duxford). This ended the type's airline service history.
The VC10 served its intended market for a mere decade and a half. Fully written down and amortised by the 1970s, it could have continued in airline service much longer despite its high fuel consumption but high noise levels on departure and approach sealed its fate. Hush-kitting the Conways was considered in the late 1970s but rejected on grounds of cost.

Military service
1960s and 1970s

In 1960, the RAF issued Specification 239 for a strategic transport, which resulted in an order being placed by the Air Ministry with Vickers in September 1961 for five VC10s. The order was increased by an additional six in August 1962, with a further three aircraft cancelled by BOAC added in July 1964.[11] The military version (Type 1106) was a combination of the Standard combi airframe with the more powerful engines and fin fuel tank of the Super VC10.[12] It also had a detachable in-flight refuelling nose probe and an auxiliary power unit in the tailcone. Another difference from the civil specification was that all the passenger seats faced backwards for safety reasons.[13]
The first RAF machine (designated VC10 C Mk. 1, often abbreviated to VC10 C1), was delivered for testing on 26 November 1965,[14] with deliveries to No. 10 Squadron beginning in December 1966 and ending in August 1968. The VC10s were named after Victoria Cross (VC) medal holders, displaying the VC holder's name above the forward passenger door. VC10 C1 aircraft were supplied to the RAF in specific configuration of a forward freight door (as per the K3), the "super" VC10 wing (as per the K3 and K4) and the fin fuel tank.
One aircraft (XR809) was leased to Rolls-Royce for flight testing of the RB211 turbofan between 1969 and 1975. On return to the RAF it was found that the airframe had become distorted, due to the increase in power from the RB211 fitted to one side of the fuselage over the Conways fitted to the other side. It was considered uneconomical to repair and was instead used for SAS training, before being scrapped.
In late 1977, studies were started into converting redundant commercial VC10s into air-to-air refuelling tankers,[15] with the RAF placing a contract with British Aerospace to convert five former BOAC (that had been operated by Gulf Air) Standard VC10s and four former East African Airways Super VC10s as air-to-air refuelling tankers.[16] These were designated VC10 K2 and VC10 K3 respectively. During conversion, extra fuel tanks were installed in what was previously the passenger cabin. These increased the theoretical maximum fuel load to 85 tons/77 tonnes (K2) and 90 tons/82 tonnes (K3); the fin fuel tank of the Super VC10 making the difference. In practice, the fuel load would be capped by the maximum take-off weight before the tanks are completely full. Both variants had refuelling pods mounted under the wings and a centreline refuelling point, known as a Hose Drum Unit (HDU), was installed in the rear freight bay. An in-flight refuelling probe was fitted on the nose, allowing fuel to be taken from the VC10, Victor or TriStar tankers.
Conversion to K2, K3 and K4 tanker role of the previous civil aircraft took place at BAE Systems Filton site. Because the K3s had a forward freight door this facilitated the insertion of five upper fuselage tanks in the main fuselage of the aircraft. In the case of the K2s, there was no forward freight door and it was required to dismantle a large section of the fuselage roof structure for the insertion of the five upper fuselage tanks. This proved to a mammoth task. In the K2 and K3 conversions extensive floor reinforcement was required to accommodate the additional weight of the five tanks and fuel load. K2 and K3 aircraft were classed as three point tankers, consisting of two wing mounted HDU and one centre fuselage HDU.

1980s and 1990s

In 1981, 14 former British Airways Super VC10s were purchased, and these were placed in storage and some were used for spare parts. The Dual Carousel navigation system of the Supers were fitted to the Operation Black Buck Vulcan bombers during the Falklands War to enable them to navigate over open ocean.[17] In the early 1990s, five of the aircraft were revived and converted to VC10 K4 tankers. Upon examination prior to the first "major" in-depth servicing of the K4s it was discovered that there was extensive wing plank corrosion in the lower surface of the wings. This was attributed mainly to the storage method used prior to conversion, whereby the wing tanks were defuelled but then filled with water, in order to add ballast to the aircraft during storage. This led to an extensive wing plank corrosion rectification and in some cases plank replacement during subsequent major services. For the K4 conversions, as with the K2 aircraft, there was no facility of a forward freight door. For this reason it was decided that there would be no internal refuelling tanks fitted to the K4s. The K4 has identical refuelling equipment to the K2 and K3, but does not have any extra fuel tanks in the fuselage. Its fuel capacity remains at 80 tons (70 tonnes), the same as a Super VC10.
During the late 1980s and early 1990s, the 13 surviving C1s were also equipped with wing-mounted refuelling pods (HDUs) and re-designated as VC10 C1K dual-rôle two-point tanker/transports. Again, no extra tanks were provided and the fuel load remains at 80 tons (70 tonnes). The C1s did not therefore require the strengthened flooring. The conversions were undertaken by FR Aviation Limited based at Hurn Airport, near Bournemouth. The in-flight refuelling probe was a feature of the original RAF aircraft, but it was removed for a period during the 1970s and 1980s due to lack of use. The probe was refitted sometime before the tanker conversions took place.
In 1982 VC10 C1s were part of the airbridge between RAF Brize Norton and Wideawake Airfield on Ascension Island during Operation Corporate, the campaign to retake the Falkland Islands.[18] In 1991 9 K2s and K3s deployed to Bahrain, Saudi Arabia and Oman as part of Operation Granby, the UK's contribution to the campaign to remove Iraqi forces from Kuwait, during which they flew 381 sorties.

In 1992, XR806 suffered a flash fire in a wing fuel tank, whilst undergoing major maintenance and fuel leak rectification. The aircraft was repaired and returned to service. In 1997, XR806 was damaged beyond economic repair in a ground de-fuelling accident at RAF Brize Norton. The aircraft overbalanced backwards damaging the rear cone of the fuselage including the rear pressure bulkhead and lower sections of the rudder.
VC10 tankers enabled RAF Bruggen-based Tornado GR1s to strike Serbian targets during Operation Allied Force in 1999.

2000s

Oman-based VC10s refuelled USAF and Marine Corps aircraft over Afghanistan as part of Operation Veritas. Nine VC10s participated in Operation Telic, the UK's contribution to Operation Iraqi Freedom.[18]
The K2s were retired and scrapped between 2000 and 2003. In 2006 two VC10s were dispatched to Okinawa, Japan to undertake a lesser known role of the type; to conduct nuclear debris tests using sampling pods replacing the refuelling pods. This was prompted by the North Korean nuclear test.[18]
VC10 air-to-air refuelling aircraft supported the British air strikes on Libya on 19–20 March 2011 as part of the coalition operations to enforce UN Resolution 1973.[19]
The surviving C1Ks and K3s serve as tanker/transports with No. 101 Squadron at Brize Norton, Oxfordshire and the one remaining K4 supports No. 1312 Flight at RAF Mount Pleasant in the Falkland Islands.[20] The VC10 and Lockheed TriStar tanker/transports are due to be replaced in RAF service by the Airbus A330 MRTT Voyager under the Future Strategic Tanker Aircraft Project. As of July 2012 they are expected to retire by 31 March 2013.[20]

Servicing and repair
All servicing of the RAF fleet of VC10s was undertaken at RAF Brize Norton in a purpose built hangar. Known as "Base Hangar" when built in 1969 was considered the largest cantilever-roofed structure in Europe; a quarter of a mile in length with no internal supports. Six VC10 aircraft could be positioned inside with adequate room to provide working space around the aircraft.
During the late 1980s, plans to move major servicing to RAF Abingdon near to RAF Brize Norton were considered. Abingdon was closed and a new facility was built at RAF St Athan, in South Wales - "1 Air Maintenance Sqn" (1 AMS). The first aircraft to undergo major servicing at the new facility entered in January 1993. One of the two lines was later turned over for the use of Tornado aircraft.
BAE Systems support[edit]
After the closure of the British Aerospace factories at Brooklands/Weybridge and Hatfield, responsibility of design and all commercial activity transferred to British Aerospace (now BAE Systems) Manchester, Woodford and Chadderton sites. In the mid-1990s, when the design of detailed components was subcontracted, the design team transferred from Woodford to Chadderton.
In 2003, responsibility for the commercial procurement of all spares items was undertaken by BAE Systems, at BAE Systems Samlesbury. The Chadderton site maintained responsibility for the MoD contracts for project managing modifications; major repairs and major maintenance being carried out at RAF St Athan.

Vickers-Armstrongs

                                                

Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977.

History

Vickers merged with the Tyneside-based engineering company Armstrong Whitworth, founded by W. G. Armstrong, to become Vickers-Armstrongs, Ltd. Armstrong Whitworth and Vickers had developed along similar lines, expanding into various military sectors and produced a whole suite of military products. Armstrong Whitworth were notable for their artillery manufacture at Elswick and shipbuilding at a yard at High Walker on the River Tyne

Break-up

In 1960 the aircraft interests were merged with those of Bristol, English Electric and Hunting Aircraft to form the British Aircraft Corporation (BAC). This was owned by Vickers, English Electric and Bristol (holding 40%, 40% and 20% respectively). BAC in turn owned 70% of Hunting. TheSupermarine operation was closed in 1963 and the Vickers brand name for aircraft was dropped by BAC in 1965. Under the terms of the Aircraft and Shipbuilding Industries Act 1977 BAC was nationalised to become part of British Aerospace (later BAE Systems).The Aircraft and Shipbuilding Industries Act also led to the nationalisation of Vickers' shipbuilding division as part of British Shipbuilders. This division was privatised as Vickers Shipbuilding and Engineering Ltd (VSEL) in 1986, later passing to the GEC group as part of Marconi Marine and survives to this day as part of BAE Systems; BAE Systems Submarines.

Vickers Container and Packaging Machinery Division, including the Vickers Stitcher and Vickers Hardness Machine business, was bought by Fords Industrial Products, part of Barry Wehmiller in 1986. In 1991 the Vickers Hardness Machinery business was bought by the then field engineers, and continues today as UK Calibrations Limited based in Kidderminster. The Vickers Stitcher was still being manufactured in India as recently as 2005.
The steelmaking division became part of British Steel and the remaining interests were divested as the public company Vickers plc, whose various components were later split. The Vickers name ceased to exist in 2003 when Rolls-Royce renamed its acquisitions Vinters plc.

Businesses
Armaments

Vickers-Armstrongs inherited the Vickers machine gun of 1912 used in World War I from Vickers Limited. There were other Vickers machine guns aside from the regular water-cooled model (known universally as the "Vickers"): the Vickers-Berthier (VB) machine gun used by the Indian Army, the Vickers "K" .303 aircraft machine gun developed from it, and the Vickers "S" 40 mm aircraft gun. An unusual machine gun also made was the Vickers Higson.
Vickers produced larger weapons such as the Ordnance QF 2 pounder gun used on tanks. 
In 1948 Vickers bought the Australian business of Charles Ruwolt Ltd for 750,000 pounds following Ruwolt's death in 1946. During WW2 Ruwolt's firm produced armaments for the Australian Government, including field artillery such as mortars and howitzer cannon.

Shipbuilding

After the 1927 merger, the company possessed a major yard on each coast of Britain; the Naval Construction Yard of Vickers at Barrow-in-Furness in Cumbria and the Naval Yard of Armstrong Whitworth at High Walker on the River Tyne. Vickers-Armstrongs was one of the most important warship manufacturers in the world. These interests were renamed as Vickers-Armstrongs Shipbuilders in 1955, changing again to Vickers Limited 
Shipbuilding Group in 1968. The Barrow yard was nationalised and became part of British Shipbuilders in 1977, was privatised as VSEL in 1986 and remains in operation to this day as BAE Systems Submarines. Meanwhile the Naval Yard at High Walker on the River Tyne passed to Swan Hunter in 1968, was nationalised and became part of British Shipbuilders in 1977, was privatised still as Swan Hunter in 1986 but closed down during the 1980s.

Military vehicles
The company was also known for its tank designs, starting with the widely used Vickers 6-Ton. It also produced the influential, if never actually produced, Independent A1E1 tank. One of the company's most important designs was the Valentine Infantry Tank, produced in the thousands in World War II. The military vehicle manufacturing interests were divested into Vickers plc, and would later pass to Alvis Vickers, now part of BAE Systems Land and Armaments.

Aviation

Vickers formed their Aviation Department in 1911. The aircraft interests of Armstrong Whitworth were not acquired in the merger and later passed to the Hawker Aircraft group. 
In 1928 the Aviation Department became Vickers (Aviation) Ltd and soon after acquired Supermarine Aviation Works, which became the Supermarine Aviation Works (Vickers) Ltd and was responsible for producing the revolutionary Spitfire fighter. In 1938, both companies were re-organised as Vickers-Armstrongs (Aircraft) Ltd, and a new 'art deco' headquarters designed by architect C. Howard Crane was built at its Brooklands factory in Surrey although the former Supermarine and Vickers works continued to brand their products under their former names. In 1960 the aircraft interests were one of the founding companies merged to form BAC. The hovercraft activities of Vickers-Armstrong were merged with those of the Westland Aircraft company (including those of Saunders-Roe) to form the British Hovercraft Corporation in 1966 with Vickers holding 25% of the new 
company. Westland bought out Vickers interest along with other partners in 1970.
Vickers formed a subsidiary, the Airship Guarantee Company, under the direction of Cdr Dennis Burney solely for the purpose of producing the R100 airship for the government.

Military aircraft

Vickers became renowned as a manufacturer of large aircraft at its main factory at Brooklands in Surrey. In the inter-war years the company produced the Wellesley designed by Rex Pierson using the geodetic airframe principle of structural engineer Barnes Wallis. This would later evolve into the famous Wellington bomber, a mainstay of RAF Bomber Command and RAF Coastal Command during World War II. The cold 
war-era Valiant V bomber was another Vickers product.

Vickers Viscount Turboprop airliner and freighter:

Type:
Turboprop airliner and freighter

History:
Vicker's Viscount was the first turboprop airliner from any nation to
enter service.
The Viscount was one of the results of the UK's wartime Brabazon
Committee, which was set up to define requirements for British postwar
commercial aircraft. Discussions between the committee and Vickers
designers in late 1944, who had already been working on the VC-1
Viking airliner development of the Wellington bomber, resulted in what
was eventually to become the Viscount. The committee's requirement was
for a 24 seat 1000 mile (1600km/868nm) range airliner, and by the end
of 1945 Vickers had selected the Rolls-Royce Dart turboprop engine
that was then under development to power the new aircraft.
In March 1946 the British government placed a contract with Vickers to
build two prototypes of its design (then called Viceroy), one powered
by Darts, the other by Armstrong Siddeley Mamba turboprops. By the
time of the Dart powered prototype's first flight on July 16 1948 the
design had grown to seat 34 and was designated Type 630. The second
prototype, the Type 663, was powered by two Rolls-Royce Tay jet
engines. Airline indifference to the 34 seat Viscount and the
availability of more powerful Dart variants however led Vickers to
stretch the design to seat 40. This development was designated the
Type 700, and first flew on April 19 1950.
Airline interest in the Viscount 700 was much stronger, and after
receiving certification on April 17 1953 it entered service with BEA
the following day. The Viscount was the subject of numerous large
orders including from North America, its smoothness, good operating
economics and pressurisation contributing to its success.
Capitalising on the 700's success Vickers developed the stretched 800
with seating for up to 69, while the final Viscount development was
the 810 with more powerful engines and higher weights.

Victa Aircruiser Four Seat Light Aircraft



The Victa Aircruiser was an 1960s Australian four-seat touring
monoplane designed by Henry Millicer and built by Victa.

History:-

The Victa Aircruiser was designed by Dr Henry Millicer, who had
earlier designed the two seat Victa Airtourer (described separately),
the most popular light aircraft designed and built in Australia. With
Airtourer production in full swing in the early 1960s Victa
commissioned Dr Millicer to develop a four seat light aircraft based
on the Airtourer. This resulted in the Aircruiser 210CS, which flew
for the first time on July 17 1966. The Aircruiser was later awarded
full Australian certification equivalent to US FAR Part 23 standards.
         The Aircruiser showed considerable promise and looked a
worthy competitor to American four seaters, however Victa withdrew
from light aircraft production in January 1967 due to the Airtourer's
inability to compete on price against alleged dumped imports to
Australia, and the design and production rights to the Airtourer and
Aircruiser were sold to AESL of New Zealand in 1970. AESL continued to
build the Airtourer and used the Aircruiser as the basis for its CT-4
Airtrainer (described separately) but did not put the Aircruiser into
production.
In 1994 Tony Peters, a flying school proprietor in Mount Gambier in
South Australia, commissioned a market study into two and four seat
light aircraft demand in Australia which found there existed a
significant market for new aircraft. A syndicate was formed to
purchase the Aircruiser design and type certificate, with Millicer
Aircraft Industries established to place an upgraded development of
the Aircruiser into production as the M-9-200 Shrike. The Shrike name
was dropped in 1998 in favour of AirCruiser (with an upper case "C").
Originally plans envisaged the first M-9-200 being delivered in mid
1997 but minor delays and the decision to acquire the Airtourer design
and place it into production as a priority meant that the first
M-9-200 - the rebuilt Aircruiser prototype - was not due to fly until
September 1999 with first customer deliveries planned for 2000.
AirCruisers and AirTourers would be built in a new, purpose designed
factory in Sale in Victoria.
    Compared with the original Victa Aircruiser, the M-9-200
AirCruiser would have featured a fuel injected IO-360 engine, standard
GPS, new wheels, brakes and controls. A retractable undercarriage
variant was also planned. However, in late 2000 Millicer ceased
trading due to financial difficulties, before the M-9-200 had been
flown. present day, only one Aircruiser was built.


Victa Aircruiser:-

Role:-            Four-seat light touring monoplane
National origin:- Australia
Manufacturer:-    Victa
Designer:-        Henry Millicer
First flight:-    18 July 1966
Number built:-    1
Developed from:-  Victa Airtourer
Variants:-        AESL CT/4 Airtrainer


Development:-

Following the success of the earlier Airtourer, Millicer designed a
four-seat version which he called the Aircruiser.The prototype
registered VH-MVR first flew on 18 July 1966. Like the airtourer it
was a low-wing monoplane with a fixed nosewheel landing gear and
powered by a 210 hp (157 kW) Continental IO-360-H piston engine.
Rather than the sliding roof of the Airtourer the four-seat Aircruiser
had a fixed cabin roof.
   Following the sale of the design rights of the Airtourer to Aero
Engine Services Limited (AESL) of New Zealand the rights to the
Aircruiser were also sold to AESL in 1969. AESL re-designed the
aircraft as the AESL CT/4 Airtrainer, a fully aerobatic military
trainer.

Light aircraft:-

A light aircraft is an aircraft that has a maximum gross take-off
weight of 12,500 lb (5,670 kg) or less. Many light aircraft are used
commercially for passenger and freight transport, sightseeing,
photography and other similar roles as well as personal use.

Examples of light aircraft include:-

1.Cessna, the entire range of propeller driven aircraft from the
Cessna 120 up to the Cessna 208
2.Piper, all models
3.Beechcraft, the non-jet models such as the Bonanza and Baron
4.Others such as Cirrus aircraft; the GippsAero GA8 Airvan; the Aviat
Husky and the Robin DR400.

Examples of aircraft that are at the maximum gross take-off weight for
this category include the de Havilland Canada DHC-6 Twin Otter and
Beechcraft B200 Super King Air.

Uses:-

The many uses of light aircraft include aerial surveying, such as
monitoring pipelines. They are also used for light cargo operations,
such as "feeding" cargo hubs, as well as some passenger operations.
Light aircraft are also used for marketing purposes, such as banner
towing and skywriting. Primary flight instruction is also conducted in
light aircraft. Finally, most personal aircraft are light aircraft,
the most popular being the Cessna 172. The Cessna 172 is not only the
most popular light aircraft, but also the most produced aircraft of
any kind.Larger light aircraft, such as twin turboprops and very light
jets are often used as business aircraft.
