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 ...

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] |

Macchi M
Aermacchi was an Italian aircraft manufacturer. Formerly known as Aeronautica Macchi, the company was founded in 1912 by Giulio Macchi at Varese in north-western Lombardy as Nieuport-Macchi, to build Nieuport monoplanes under licence for the Italian military. With a factory located on the shores of Lake Varese, the firm originally manufactured a series of Nieuport designs, as well as seaplanes. After World War II, the company began producing motorcycles as a way to fill the post-war need for cheap, efficient transportation. The company later specialised in civil and military pilot training aircraft.

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] |
Boulton Paul Balliol
The Boulton Paul Balliol and Sea Balliol are monoplane advanced trainer aircraft designed and produced by the British aircraft manufacturer Boulton Paul Aircraft. On 17 May 1948, it became the world's first single-engined turboprop aircraft to fly. The Balliol was operated primarily by both the Royal Air Force (RAF) and the Royal Navy Fleet Air Arm (FAA). Developed during the late 1940s, the Balliol was designed to fulfil Air Ministry Specification T.7/45, replacing the wartime North American Harvard trainer. Unlike previous trainer aircraft, which were powered by piston engines, it was specified for the aircraft to use newly developed turboprop propulsion instead. On 30 May 1947, the Balliol performed its maiden flight; the first preproduction aircraft would fly during the following year. Production examples were powered by the Rolls-Royce Merlin engine, while various prototypes and pre-production aircraft featured alternative powerplants such as the Rolls-Royce Dart and Armst ...

Avro Athena
The Avro 701 Athena is a British advanced trainer aircraft built by Avro in the late 1940s. It was designed to replace the North American Harvard in the Royal Air Force, but was bought only in small numbers, the competing Boulton Paul Balliol being preferred. Design and development The Athena was designed to meet the requirements of Air Ministry Specification T.7/45 for a three-seat advanced trainer powered by a turboprop engine for the RAF. The Athena was an all-metal low-winged monoplane, with a side-by-side cockpit. The Air Ministry rethought its requirements in 1947 and replaced the original specification with Specification T.14/47, which specified the use of a Rolls-Royce Merlin 35 piston engine, large stocks of which were held in store. Despite the change in specification, the first three prototypes were of the turboprop-powered Athena T.1, the first of which, powered by an Armstrong Siddeley Mamba engine, flew on 12 June 1948 at Woodford Aerodrome.
