Avro: Британдық ұшақ құрастырушысының тарихы

British aircraft manufacturer
the British aircraft manufacturer that existed from 1910 to 1963

Avro (an initialism of the founder's name) was a British aircraft manufacturer. Its designs include the Avro 504, used as a trainer in the First World War, the Avro Lancaster, one of the pre eminent bombers of the Second World War, and the delta wing Avro Vulcan, a stalwart of the Cold War. Avro was founded in 1910 by Alliott Verdon Roe at the Brownsfield Mill on Great Ancoats Street in Manchester. The company remained based primarily in Lancashire throughout its 53 years of existence, with key development and manufacturing sites in Alexandra Park, Chadderton, Trafford Park, and Woodford, Greater Manchester. The company was merged into Hawker Siddeley Aviation in 1963, although the Avro name has been used for some aircraft since then.

One of the world's first aircraft builders, A. V. Roe and Company was established on 1 January 1910 at Brownsfield Mill, Great Ancoats Street, Manchester, by Alliott Verdon Roe and his brother Humphrey Verdon Roe. 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. Alliot had already constructed a successful aircraft, the Roe I Triplane, named The Bullseye after a brand of braces manufactured by Humphrey. The railway arch where A. V. Roe in 1909 built and achieved the first all British powered flight still stands in the Lee Valley Park on the Walthamstow Marshes. In 1911, Roy Chadwick began work as Alliott's personal assistant and the firm's draughtsman and, in 1918, he was appointed Chief Designer. 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 Royal Flying Corps. 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 World War I, and the type saw some front line service in the early months of the war, but it is best known as a training aircraft, serving in that role until 1933. Production lasted 20 years and totalled 8,340 aircraft from several factories: Hamble, Failsworth, Miles Platting and Newton Heath.

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 which 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 since 1918; the site was used for a mixture of recreation and housing development. A rural site to the south of the city was found at New Hall Farm, Woodford in Cheshire, which continued to be used by aviation company BAE Systems until March 2011; the site has now been earmarked for a mixed use development. In 1928 Crossley Motors sold AVRO to Armstrong Siddeley Holdings Ltd. The old taxiway from the factory to the runway is still evident. The Avro Lancaster carried the heaviest bomb loads of the war, including the Grand Slam bomb.

The civilian Lancastrian and maritime reconnaissance Shackleton were derived from the successful Lancaster design. The Tudor was a pressurised but problematic post war Avro airliner which faced strong competition from designs by Bristol, Canadair, Douglas, Handley Page, and Lockheed. 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 older Avro York was somewhat more successful in both the RAF and in commercial service, being distinguished by a fuselage square in cross section. Both Tudors and Yorks played an important humanitarian part in the Berlin Airlift. The postwar Vulcan bomber, originally designed as a nuclear strike aircraft, was used to maintain the British nuclear deterrent, armed with the Avro Blue Steel stand off nuclear bomb. The Vulcan saw service as a conventional bomber during the British campaign to recapture the Falkland Islands in 1982. Several Vulcans are prized as museum exhibits. A twin turboprop airliner, the Avro 748, was developed during the 1950s and sold widely to airlines and governments across the globe, powered by two Rolls Royce Dart engines. The RAF bought 6 for use by the Queen's Flight and a variant with a rear loading ramp and a "kneeling" main undercarriage was sold to the RAF (31 aircraft) as the Andover.

The Avro name would subsequently be resurrected by British Aerospace when this aircraft manufacturer renamed its BAe 146 family of regional jetliners as Avro regional jets (Avro RJ). Three differently sized versions of the four engine jetliner were produced: the Avro RJ70, the Avro RJ85 and the largest example, the Avro RJ100.

In 1945, Hawker Siddeley Group purchased the former Victory Aircraft firm in Malton, Ontario, and renamed the operation A. V. Roe Canada Limited. Commonly known as Avro Canada, it was actually a subsidiary of the Hawker Siddeley Group and used the Avro name for trading purposes.

When the company was absorbed into Hawker Siddeley Aviation in July 1963 following the 1957 Defence White Paper, the Avro name ceased to be used. The brand still had a strong heritage appeal, and as mentioned above the marketing name "Avro RJ" (regional jet) was used by British Aerospace from 1994 to 2001 for production of the RJ70, RJ85 and RJ100 models which were respectively based on the BAe 146 100, BAe 146 200 and BAe 146 300. This four engine jet aircraft type is sometimes also loosely called the "Avro 146". The BAe ATP (Advanced Turbo Prop) design evolved from the Avro 748 and examples continue in use on shorter, mainly domestic, scheduled air services. A few Avro 504s, Tutors, Ansons and Lancasters are maintained in flying condition. 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.

Avro also built motor vehicles in the immediate post World War 1 era, including the three wheeler Harper Runabout, as well as their own light car. Powered by a 1,330 cc 4 cylinder engine, wood and aluminium were used in an integral construction similar to an aircraft. Approximately 100 were built. In 1927 Alliott Verdon Roe designed a two wheeler car powered by a 350 cc Villiers air cooled engine. An outrigger wheel kept the car upright when stationary. The Mobile did not go into production.

Avro F. C. was founded at the Chadderton factory and still exists today.
