Cierva W.11 Air Horse
The Cierva W.11 Air Horse was a helicopter developed by the Cierva Autogiro Company in the United Kingdom during the mid-1940s. The largest helicopter in the world at the time of its debut, the Air Horse was unusual for using three rotors mounted on outriggers, and driven by a single engine mounted inside the fuselage. Development The W.11 "Air Horse" heavy lift helicopter was developed by the G & J Weir, Ltd., Aircraft Department, reconstituted in 1943 as the Cierva Autogiro Company. The "W" in the designation is a continuation of the autogiro and helicopter series developed by G & J Weir, Ltd., during the period 1932–1940. The W.11 was a development of the Weir W.6 dual transverse rotor helicopter. It is the only helicopter of its type ever built and included three lifting rotors all turning in the same direction. The adoption of three rotors was due to concerns over the capability of a single large rotor to generate the required lift. Torque balance was provided by slightly ...

Cierva Autogiro Company
The Cierva Autogiro Company was a British firm established in 1926 to develop the autogyro. The company was set up to further the designs of Juan de la Cierva, a Spanish engineer and pilot, with the financial backing of James George Weir, a Scottish industrialist and aviator. History Juan de la Cierva's first British-built autogyro was the C.8 design. It and some other designs were built in conjunction with Avro. The pre-war Cierva C.30 proved popular. Nearly 150 were built under licence in the United Kingdom by Avro, in Germany by Focke-Wulf, and in France by Lioré-et-Olivier. On 9 December 1936, Cierva was killed in the Croydon KLM airliner accident when the aircraft in which he was a passenger crashed after taking off in fog. Dr. James Allan Jamieson Bennett was promoted to Chief Technical Officer of the company and remained in the position until leaving in 1939. In addition to making important contributions to autogyro controls while at Cierva Autogyro, Bennett carried th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Ministry Specification
This is a partial list of the British Air Ministry (AM) specifications for aircraft. A specification stemmed from an Operational Requirement, abbreviated "OR", describing what the aircraft would be used for. This in turn led to the specification itself, e.g. a two-engined fighter with four machine guns. So for example, OR.40 for a heavy bomber led to Specification B.12/36. Aircraft manufacturers would be invited to present design proposals to the ministry, following which prototypes of one or more of the proposals might be ordered for evaluation. On very rare occasions, a manufacturer would design and build an aircraft using their own money as a "private venture" (PV). This would then be offered to the ministry for evaluation. If the aircraft generated interest in the ministry or RAF due to performance or some other combination of features then the ministry might well issue a specification based on the private venture aircraft. The system of producing aircraft to a specification ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Farnborough Air Show
The Farnborough Airshow, officially the Farnborough International Airshow, is a trade exhibition for the aerospace and defence industries, where civilian and military aircraft are demonstrated to potential customers and investors. Since its first show in 1948, Farnborough has seen the debut of many famous planes, including the Vickers VC10, Concorde, the Eurofighter, the Airbus A380, and the Lockheed Martin F-35 Lightning II. At the 1958 show, the RAF's Black Arrows executed a 22-plane formation loop, setting a world record. The international trade show is put together every two years by FIL Farnborough International Ltd. and runs for five days. Until 2020, the show ran for a full week with trade visitors attending on the first five days and the weekend reserved for the general public. Programming takes place at the Farnborough Airport, which lies roughly 50 kilometres south-west of London. Status The Farnborough International Airshow is the second-largest show of its kind afte ...

Saro Skeeter
The Saunders-Roe Skeeter was a two-seat training and scout helicopter that was developed and produced by British manufacturer Saunders-Roe ("Saro") of Cowes and Southampton, in the United Kingdom. Work on what would become the Skeeter had been commenced by the Cierva Autogiro Company as the Cierva W.14. Following Saunders-Roe's takeover of Cierva's helicopter development contracts, it was decided to continue its projects, including the Skeeter. Despite an initial preference for the rival Fairey Ultra-light Helicopter, which had already been ordered, there was a reversal of fortune with interest from the Bundeswehr in the potential procurement of a large number of Skeeters. This led to the British order for the Ultra-light Helicopter being cancelled and the Skeeter effectively taking its place, which also served to guarantee an export order from Germany. During the late 1950s, the Skeeter entered service with the British Army Air Corps, the German Navy, and the German Army. It ...

Saunders Roe
Saunders-Roe Limited, also known as Saro, was a British aero- and marine-engineering company based at Columbine Works, East Cowes, Isle of Wight. History The name was adopted in 1929 after Alliott Verdon Roe (see Avro) and John Lord took a controlling interest in the aircraft and boat-builders S. E. Saunders. Prior to this (excepting for the Sopwith/Saunders Bat Boat) the products were Saunders, the A4 Medina for example dating from 1926. Sam Saunders the founder developed the Consuta material used in marine and aviation craft. The Saunders-Roe interest in aviation didn’t prevent the firm from continuing with the boatbuilding activities associated with S. E. Saunders Ltd Saunders Roe concentrated on producing flying-boats, but none were produced in very large quantities – the longest run being 31 Londons. They also produced hulls for the Blackburn Bluebird. During the Second World War Saro manufactured Supermarine Walrus and Supermarine Sea Otters. Their works a ...

Rolls-Royce Dart
The Rolls-Royce RB.53 Dart is a turboprop engine designed and manufactured by Rolls-Royce Limited. First run in 1946, it powered the Vickers Viscount on its maiden flight in 1948. A flight on July 29 of that year, which carried 14 paying passengers between Northolt and Paris–Le Bourget Airport in a Dart-powered Viscount, was the first regularly scheduled airline flight by a turbine-powered aircraft.Turner 1968, p. 9. The Viscount was the first turboprop-powered aircraft to enter airline service - British European Airways (BEA) in 1953. The Dart was still in production forty years later when the last Fokker F27 Friendships and Hawker Siddeley HS 748s were produced in 1987. Following the company's convention for naming gas turbine engines after rivers, this turboprop engine design was named after the River Dart. History Designed in 1946 by a team led by Lionel Haworth, the Dart had a two-stage centrifugal compressor design derived from the earlier Rolls-Royce Clyde. The Dart ...

Colonial Office
The Colonial Office was a government department of the Kingdom of Great Britain and later of the United Kingdom, first created to deal with the colonial affairs of British North America but required also to oversee the increasing number of colonies of the British Empire. Despite its name, the Colonial Office was never responsible for all Britain's Imperial territories; for example, protectorates fell under the purview of the Foreign Office, and British India was ruled by the East India Company until 1858 (the British Raj ruled the India Office as a result of the Indian Mutiny), while the role of the Colonial Office in the affairs of the Dominions changed as time passed. It was headed by the Secretary of State for the Colonies, also known more informally as the Colonial Secretary. First Colonial Office (1768–1782) Prior to 1768, responsibility for the affairs of the British colonies was part of the duties of the Secretary of State for the Southern Department and a committe ...
