Axelson Aircraft Engine Company

The Axelson Aircraft Engine Company was a manufacturer of aircraft engines based in Los Angeles in the late 1920s.
Their engines were originally known as ‘Floco’, because the manufacturer was originally Frank L. Odenbreidt Co. Their products included the 115 hp Axelson A-7-R and 150 hp Axelson B. Axelson engines were used to power the Swallow F28-AX, among other contemporary aircraft.

Avtek Corp

Established in 1982, flew proof-of-concept prototype for the intended Avtek 400A pressurised, composites-built, six/nine-seat business jetfan in September 1984. Avtek has rear-mounted main wings, canards, and twin turboprops with pusher propellers. Avtek 400A was expected to be certificated in 2000.

The company went bankrupt in 1998.

Avro Canada / Avro Aircraft Ltd

During the Second World War, Victory Aircraft in Malton, Ontario was Canada’s largest aircraft manufacturer. Prior to 1939, as a part of National Steel Car Ltd. of Hamilton, the concern had been one of a number of “shadow factories” set up in Canada to produce British aircraft designs in safety. National Steel Car had turned out Avro Anson trainers, Handley Page Hampden bombers, Hawker Hurricane fighters and Westland Lysander army cooperation aircraft. National Steel Car Corporation of Malton, Ontario was formed in 1938 and renamed Victory Aircraft Limited in 1942 when the Canadian government took over ownership and management of main plant. During the Second World War, Victory Aircraft built Avro (UK) aircraft: 3,197 Anson trainers, 430 Lancaster bombers, six Lancastrian, one Lincoln bomber and one York transport.

In 1944, an Advisory Committee on Aircraft Manufacture was established by the Canadian government, the Canadian Director of Aircraft Production wrote to Minister of Munitions and Supply C.D. Howe in 1944 to express the “utmost importance to Canada” of the establishment of a Canadian aircraft industry, and UK-based Avro also established in 1944 a company searching for post-war opportunities. Bob Leckie of the RCAF was a strong advocate for years for an industry to design and build aircraft in Canada yet the Department of National Defense, according to Avro’s Roy Dobson, gave “a cold reception” to doing more than building under licence. Howe, as Minister of Reconstruction and Minister of Munitions and Supply (later Reconstruction and Supply), brokered the deal with the Hawker Siddeley Group to take over the Victory Aircraft plant in 1945 with Frederick T. Smye hired by HSG’s Roy Dobson as its first employee.

In 1945, the UK-based Hawker Siddeley Group purchased Victory Aircraft from the Canadian government, creating A.V. Roe Canada Ltd. as the wholly owned Canadian branch of its aircraft manufacturing subsidiary, UK-based A.V. Roe and Company. Avro Canada began operations in the former Victory plant. Avro Aircraft (Canada), their first (and, at the time, only) division, turned to the repair and servicing of a number of Second World War-era aircraft, including Hawker Sea Fury fighters, North American B-25 Mitchell and Avro Lancaster bombers. From the outset, the company invested in research and development and embarked on an ambitious design program with a jet engine and a jet-powered fighter and airliner on the drawing boards.

The new company produced the first Canadian-designed jet fighter, the twin-engined CF-100. Prototype flew in 1950; 639 were built for the RCAF and 53 for the Belgian Air Force. Flew prototype C-102 Jetliner in 1949, but no production order was received. Avro Canada became a member of the Hawker Siddeley Group in 1955, and in 1962 became Hawker Siddeley Canada Ltd. CF-105 Arrow delta twin-jet all-weather fighter prototype flew in 1958. Only five CF-105s were built before the project was cancelled in favour of Bomarc surface-to-air missiles. The Avrocar VTOL aircraft developed under a U.S. Department of Defense contract and flown in 1959 in California. In its prototype form it was a circular flying saucer.

A.V. Roe Canada Ltd. was restructured in 1954 as a holding company with two aviation subsidiaries: Avro Aircraft Ltd. and Orenda Engines Ltd., which began operating under these names on 1 January 1955. Each companies’ facilities were each were located across from each other in a complex at the perimeter of Malton Airport. The total labour force of both aviation companies reached 15,000 in 1958.
During the same period, with Crawford Gordon as president, A.V. Roe Canada Ltd. purchased a number of companies, including Dominion Steel and Coal Corporation, Canada Car and Foundry (1957), and Canadian Steel Improvement. By 1958, A. V. Roe Canada Ltd. was an industrial giant with over 50,000 employees in an empire of 44 companies involved in coal mining, steel making, railway rolling stock, aircraft and aero-engine manufacturing, as well as computers and electronics. In 1956 the companies generated 45% of the revenue of the Hawker Siddeley Group. In 1958, annual sales revenue was approximately $450 million, ranking A.V. Roe Canada as the third largest corporation in Canada by capitalization. By the time of the cancellation of the Arrow and Iroquois, aircraft-related production amounted to approximately 40% of the company’s activities with 60% industrial and commercial.

In 1956, 500,000 shares were issued to the public at a total value of $8 million. By 1958, 48% of the shares of A.V. Roe Canada were publicly traded on the stock exchange. Although controlled and largely owned by UK-based Hawker Siddeley Group, all profits from A.V. Roe Canada Ltd. were retained within the company to fund development and growth. Management of the Canadian companies remained in Canadian hands.

In 1962, the Hawker Siddeley Group formally dissolved A.V. Roe Canada and transferred all A.V. Roe Canada assets to its newly-formed subsidiary Hawker Siddeley Canada. Avro Aircraft was closed.

Avro / A.V.Roe

When the Daily Mail organised a model-flying contest at Alexander Palace, London, in March 1907, young A.V. Roe won first prize. His 8 ft tail first model flew more than 100 feet.

Alliott Verdon Roe, after a varied career in surveying, tree-planting, fishing, post-office management and marine engineering began aircraft design in 1906. Spurred by winning £75 in a model aircraft contest held in London in 1907. Roe built a full-size biplane, which made some tentative hops from the motor racing circuit at Brooklands in 1908.

Moving to an abandoned railway arch on Lea Marshes in Essex, he built the Roe I Triplane which weighed less than 91 kg (200 lb) and was covered in brown wrapping paper. He called it the Bull’s-Eye Avroplane after the brand-name of men’s trouser braces whose manufacturer had supported him. In July 1909 the Roe I Triplane made the first official powered flights in Britain by an all-British aircraft.
Alliott Roe subsequently developed three other triplane designs, one of which he flew (and crashed three times) at the great Boston-Harvard Aviation Meeting of 1910.

A.V. Roe and Company was established at Brownsfield Mill, Great Ancoats Street, Manchester, by Alliott Verdon Roe and his brother Humphrey Verdon Roe on 1 January 1910. Humphrey’s contribution was chiefly financial and organizational; funding it from the earnings of the family webbing business and acting as Managing Director until he joined the RFC in 1917.

In the summer of 1910 A. V. Roe and Company declared its willingness to build aeroplanes to other people’s designs and the first such aircraft was a Farman-type biplane for a Bolton business man. The Farman-type evidently did not meet with much success as 18 months later, at the end of 1912, the engine and airframe were advertised for sale in new condition for £45 and £60 respectively. Bolts, fittings and bracing wires were also supplied to Miss Lilian Bland who built and flew the Mayfly biplane of her own design at Carnamony, Belfast. Each of these aircraft was fitted with one of the few examples of the 20 h.p. two cylinder, horizontally opposed, air cooled Avro engines. These were never given an Avro designation.

A.V.Roe carried out numerous experiments with all kinds of plane sections with varying cambers, etc. These were sold off in November 1911 at peppercorn prices for gliders.

The first Avro aircraft to be produced in any quantity was the Avro E or Avro 500, first flown in March 1912, of which 18 were manufactured, most for the newly-formed RFC. The company also built the world’s first aircraft with enclosed crew accommodation in 1912, the monoplane Type F and the biplane Avro Type G in 1912, neither progressing beyond the prototype stage. The Type 500 was developed into the Avro 504, first flown in September 1913. A small number were bought by the War Office before the outbreak of the First World War and the type saw some front line service in the early months of the war, but is best known as a training aircraft, serving in this role until 1933. Production lasted 20 years and totalled 8,340 at several factories: Hamble, Failsworth, Miles Platting and Newton Heath.

By 1913 the company had become registered as A.V.Roe & Co. Ltd.

After the boom in orders during the First World War, the lack of new work in peacetime caused severe financial problems and in August 1920, 68.5% of the company’s shares were acquired by nearby Crossley Motors who had an urgent need for more factory space for automotive vehicle body building.

In 1924, the Company left Alexandra Park Aerodrome in south Manchester where test flying had taken place during the period since 1918 and the site was taken over by a mixture of recreation and housing development. A rural site to the south of the growing city was found at New Hall Farm, Woodford in Cheshire, which continued to serve aviation builders BAE Systems until March 2011.

Cierva Autogiro production started in Britain at A. V. Roe’s Hamble factory in 1926.

In 1928 Crossley Motors sold AVRO to Armstrong Siddeley Holdings Ltd. In 1928, A.V.Roe resigned from the company he had founded and formed the Saunders-Roe company that after World War II developed several radical designs for combat jets, and, eventually, a range of powerful hovercraft.

In 1928 Avro acquired a license to build the Fokker F.VIIB/3M as the Avro 618 Ten: it carried eight passengers and two crew, and orders included five for Australian National Airways. Rivaling the success of the 504 was the twin-engined Anson trainer and coastal patrol monoplane, flown as the Avro 652 civil transport for Imperial Airways in 1935.

In 1935, Avro became a subsidiary of Hawker Siddeley.

More than 10,000 Ansons were built in Britain and Canada between 1935 and 1952. The twin-engined Manchester bomber of 1939, with the unproven Rolls-Royce Vulture engines, was not a success, but led to the superb four-engined Lancaster, of which 7,374 were built during Second World War. The York transport derivative mated the same wings and tail, plus a central fin, with an entirely new fuselage seating 12 passengers. The Lincoln bomber was built as a replacement for the Lancaster, entering RAF service soon after VJ-day.

Over 7,000 Lancasters were built and of the total, nearly half were built at Avro’s Woodford and Chadderton (Manchester) sites, with some 700 Lancasters built at the Avro “shadow” factory next to Leeds Bradford Airport (formerly Yeadon Aerodrome), northwest Leeds. This factory employed 17,500 workers at a time when the population of Yeadon was just 10,000. The old taxiway from the factory to the runway is still evident.

Although only ⅓ of Lancasters hit their target, the Lancasters were at the time Britain’s best bombers.

The civilian Lancastrian and maritime reconnaissance Shackleton were derived from the Lancaster design. Avro’s postwar Tudor transport was not a success. With the same wings and engines as the Lincoln, it achieved only a short (34 completed) production run following a first flight in June 1945 and the cancellation of an order from BOAC.

The company’s last piston-engined aircraft was the Shackleton four-engined maritime reconnaissance aircraft. Following production of four Avro 707 delta research aircraft, the company produced the four-jet delta-wing Vulcan bomber, which began to enter RAF service in 1956. The Vulcan saw service as a conventional bomber during the British campaign to recapture the Falkland Islands in 1982. Vulcan XH558 flew again after several years of refurbishment, and several are prized as museum exhibits. Avro’s last design before being restyled the Avro Whitworth Division of Hawker Siddeley Aviation, in 1963, was the Avro 748 twin-turboprop transport (first flown in 1960). The Royal Flight bought a few and a variant with a rear-loading ramp and a “kneeling” main undercarriage was sold to the RAF and several members of the Commonwealth as the Andover.

When the company was absorbed into Hawker Siddeley Aviation with Folland, Gloster, Armstrong Whitworth, and de Havilland in July 1963, the Avro name ceased to be used. The brand still had a strong heritage appeal, and the marketing name “Avro RJ” (regional jet) was used by British Aerospace for production of the RJ-85 and RJ-100 models of the BAe 146 from 1994 to 2001. This aircraft type is sometimes also loosely called the “Avro 146”.
The BAe ATP (Advanced Turbo Prop) design evolved from the Avro 748. At 39 years, the Shackleton held the distinction of being the aircraft with the longest period of active RAF service, until overtaken by the English Electric Canberra in 1998.

Avions de Transport Regional

Avions de Transport Regional was founded 1982 by Aerospatiale of France and Alenia of Italy to develop a twin-turboprop regional transport aircraft. The initial ATR 42 42/48-seat airliner or freighter was first flown in August 1984, with production deliveries from 1989. Followed by the larger ATR 72 for 66-74 passengers (first flown October 1988 and also delivered from 1989). Both also available in Maritime Patrol form.
