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 ...

Low-wing Aircraft
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 ...

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] |
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. In July 2003, Aermacchi was integrated into the Finmeccanica Group (now Leonardo) as Alenia Aermacchi, which increased its shareholding to 99%. Military trainers Since the beginning, the design and production of military trainers have been the core business of Alenia Aermacchi.

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] |
Illustrated Encyclopedia Of Aircraft
The ''Illustrated Encyclopedia of Aircraft'' was a weekly partwork magazine by Aerospace Publishing (an imprint of Orbis Publishing) which was published in the United Kingdom (and sold in other countries too) during the early 1980s. The magazine was intended to eventually make up a multi-volume encyclopedia dedicated to aviation. First issued in 1981, the partwork comprised 216 issues, each of twenty pages (plus the covers), making up eighteen volumes (4280 pages). The first two issues were sold together for the price of one, subsequent issues were sold on their own. Empty binders for each volume (of twelve issues) were also sold. These binders were dark blue in colour and contained the imprint of a Panavia Tornado on the front. They held the issues using a metal strip that was threaded through the staples of each issue to hold them in place. Each issue consisted of four separate sections. The final two parts (215 and 216), issued in 1985, comprised the index for the encyclopedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
