Handley Page Basic Trainer
The Handley Page Basic Trainer (H.P.R.2) was a British training aircraft of the 1940s. It was a single-engine, low-wing monoplane with a fixed tailwheel undercarriage. Development The H.P.R.2 was developed by Handley Page Reading Ltd as a basic trainer in response to Air Ministry Specification T16/48 for a trainer to replace the ageing Percival Prentice. The Basic Trainer first flew in May 1950. Testing showed it to be a trickier and less forgiving aircraft than the rival Percival P.56. Although Handley Page were confident that the H.P.R.2 could be improved, the Air Ministry elected to order the P.56 into production as the Provost. Two prototypes (WE496 c/n HPR.142 and WE505 c/n HPR.143) were built and flown but no orders resulted. Specifications (Basic Trainer) See also References Notes Bibliography * Barnes, C. H.

Handley Page
Handley Page Limited was a British aerospace manufacturer. Founded by Frederick Handley Page (later Sir Frederick) in 1909, it was the United Kingdom's first publicly traded aircraft manufacturing company. It went into voluntary liquidation and ceased to exist in 1970. The company, based at Radlett Aerodrome in Hertfordshire, was noted for its pioneering role in aviation history and for producing heavy bombers and large airliners. History Frederick Handley Page first experimented with and built several biplanes and monoplanes at premises in Woolwich, Fambridge and Barking Creek. His company, founded on 17 June 1909, became the first British public company to build aircraft. In 1912, Handley Page established an aircraft factory at Cricklewood after moving from Barking. Aircraft were built there, and flown from the company's adjacent airfield known as Cricklewood Aerodrome, which was later used by Handley Page Transport. The factory was later sold off to Oswald Stoll and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trainer (aircraft)
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Tailwheel
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

List Of Air Ministry Specifications
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] |
Percival Prentice
The Percival Prentice was a basic trainer of the Royal Air Force in the early postwar period. It is a low-wing monoplane with a fixed tailwheel undercarriage. Front seating was in a side-by-side configuration with a rear seat provided. Design and development Designed to meet Air Ministry Specification T.23/43, the Prentice was the first all-metal aircraft to be produced by the Percival Aircraft Company. The first (of 5) prototype Prentice TV163 first flew from Percival's factory at Luton Airport, Bedfordshire on 31 March 1946. Early trials revealed lateral instability with inadequate rudder control and poor spin recovery, which required extensive tests with revised tail configurations. These resulted in modifications to the fin, rudder, elevators and upturned wingtips. An unusual design feature was the provision for three seats. While the instructor and pupil were equipped with dual controls in a side-by-side arrangement in the front, a second pupil sat in the rear seat wit ...

Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force, that existed from 1918 to 1964. It was under the political authority of the Secretary of State for Air. Organisations before the Air Ministry The Air Committee On 13 April 1912, less than two weeks after the creation of the Royal Flying Corps (which initially consisted of both a naval and a military wing), an Air Committee was established to act as an intermediary between the Admiralty and the War Office in matters relating to aviation. The new Air Committee was composed of representatives of the two war ministries, and although it could make recommendations, it lacked executive authority. The recommendations of the Air Committee had to be ratified by the Admiralty Board and the Imperial General Staff and, in consequence, the Committee was not particularly effective. The increasing separation of army and naval aviation from 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percival Provost
The Percival P.56 Provost is a basic trainer aircraft that was designed and manufactured by British aviation company Percival. During the 1950s, the Provost was developed for the Royal Air Force (RAF) as a replacement for the Percival Prentice. Designed by Henry Millicer, it was a single-engined low-wing monoplane, furnished with a fixed, tailwheel undercarriage and, like the preceding Prentice, had a side-by-side seating arrangement. First flying on 24 February 1950, the prototypes participated in an official evaluation, after which the type was selected to meet Air Ministry specification T.16/48. The Provost entered service with the RAF during 1953 and quickly proved to be more capable than the preceding Prentice. It was a relatively successful aircraft, being exported for multiple overseas operators. Various models were developed, both armed and unarmed, to meet with customer demands. The Provost later adapted to make use of a turbojet engine, producing the BAC Jet Provost. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armstrong Siddeley Cheetah XVIII
The Armstrong Siddeley Cheetah is a seven-cylinder British air-cooled aircraft radial engine of 834 cu in (13.65 L) capacity introduced in 1935 and produced until 1948. Early variants of the Cheetah were initially known as the Lynx Major.Lumsden 2003, p.74. The Cheetah was used to power many British trainer aircraft during World War II including the Avro Anson and Airspeed Oxford. Design and development The Cheetah was developed from the earlier Lynx using the increased bore cylinders from the Armstrong Siddeley Panther but the engine retained the stroke of the Lynx. Initially only direct-drive variants were produced with later engines being made available with propeller reduction gear of various ratios. Superchargers were also available for later variants, both geared and directly driven by the crankshaft. The basic design of the Cheetah remained unchanged from its introduction in 1935 to the last examples built in 1948. It was the first engine of its type to be certified f ...
