Piaggio P.150
The Piaggio P.150 was a 1950s Italian two-seat trainer designed and built by Piaggio to meet an Italian Air Force requirement to replace the North American T-6. Development The P.150 was designed and built to compete as an Italian Air Force T-6 replacement against the Fiat G.49 and Macchi MB.323. The P.150 was an all-metal low-wing cantilever monoplane with a wide-track retractable tailwheel landing gear. The pilot and instructor were seated in tandem under one glazed canopy. It was originally powered by a Pratt & Whitney Wasp radial engine and later an Alvis Leonides engine. The aircraft was not chosen and did not go into production.

Yakovlev Yak-11
The Yakovlev Yak-11 (russian: Яковлев Як-11; NATO reporting name: "Moose") is a trainer aircraft used by the Soviet Air Force and other Soviet-influenced air forces from 1947 until 1962. Design and development The Yakovlev design bureau began work on an advanced trainer based on the Yak-3 fighter in mid-1944, although the trainer was of low priority owing to the ongoing Second World War.Gunston 1995, p. 469. The first prototype of the new trainer, designated Yak-UTI or Yak-3UTI flew in late 1945. It was based on the radial-powered Yak-3U, but with the new Shvetsov ASh-21 seven-cylinder radial replacing the ASh-82 of the Yak-3U.Gordon Komissarov and Komissarov 2005, p. 249. It used the same all-metal wings as the Yak-3U, with a fuselage of mixed metal and wood construction. The pilot and observer sat in tandem under a long canopy with separate sliding hoods. A single synchronised UBS 12.7 mm machine gun and wing racks for two 100 kg (220 lb) bombs compris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valmet Vihuri
Valmet Vihuri (Finnish for ''Gale'') was a Finnish advanced two-seat fighter trainer aircraft, serving in the Finnish Air Force between 1953 and 1959. Only a few airframes have survived, as in the Central Finland Aviation Museum in Finland. History In spite of their economic problems, the aircraft manufacturer Valmet began designing a new aircraft at the beginning of the 1950s, to replace the aging Finnish Air Force (FAF) VL Pyrys. Martti Vainio was the chief designer of the project. Most of the planning was made by the aeronautical engineers L. Hämäläinen and T. Mäntysalo in 1948–49. The Bristol Mercury, then being manufactured under license in Finland for the Bristol Blenheim bomber, was chosen as the engine, since it was readily available. The prototype (VH-1) made its first flight on 6 February 1951, in Tampere, piloted by captain Esko Halme. After successful test flights, the FAF ordered 30 production aircraft, called Valmet Vihuri II, on 27 February 1951. In the autum ...

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] |
CAC Winjeel
The CAC CA-25 Winjeel is an Australian-designed and manufactured three-seat training aircraft. Entering service with the Royal Australian Air Force (RAAF) in 1955 as a basic to advanced trainer, it served in this role until 1975. Later, it was used in the Forward Air Control (FAC) role for target marking until 1994, after which it was retired from RAAF service. Design and development The Winjeel (from a Victorian indigenous word for "young eagle", an alternate spelling of Bunjil) was developed by the Commonwealth Aircraft Corporation at Fishermans Bend in Victoria to satisfy RAAF technical requirement No.AC.77 issued in 1948. Designed to replace both the Tiger Moth and the CAC Wirraway, the first two prototype CA-22 aircraft were flown in February 1951. However, it proved a very stable aircraft making it almost impossible to spin, and with this being a required part of pilot training the tail had to be redesigned as a result. Sixty-two production CA-25 aircraft were subsequently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney R-1340-S3H1 Wasp
The Pratt & Whitney R-1340 Wasp is an aircraft engine of the reciprocating type that was widely used in American aircraft from the 1920s onward. It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Wasp series. It was a single-row, nine- cylinder, air-cooled, radial design, and displaced 1,344 cubic inches (22 L); bore and stroke were both 5.75 in (146 mm). A total of 34,966 engines were produced. As well as numerous types of fixed-wing aircraft, it was used to power helicopters, the Agusta-Bell AB.102 and the Sikorsky H-19, and a class of airship, the K-class blimp. In 2016, it received designation as a Historic Engineering Landmark from the American Society of Mechanical Engineers.

Alvis Leonides
The Alvis Leonides was a British air-cooled nine-cylinder radial aero engine first developed by Alvis Car and Engineering Company in 1936. Design and development Development of the nine-cylinder engine was led by Capt. George Thomas Smith-Clarke. The prototype engine, called 9ARS and which weighed 693 lb and developed 450 hp, was run in December 1936. In 1938 Airspeed (1934) Ltd lent their test pilot, George Errington, and their much rebuilt Bristol Bulldog (''K3183''), to carry out test flights. Development was continued at a reduced pace during the Second World War and following testing in an Airspeed Oxford and an Airspeed Consul (''VX587''). Alvis was ready to market the engine in 1947 as the Series 500 (502, 503 and sub-types) for aeroplanes and Series 520 for helicopters. (Most helicopter engines were direct drive — no reduction gearbox — with a centrifugal clutch and fan cooling). The first production use was the Percival Prince, which flew in Ju ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...
