Yakovlev UT-2
The Yakovlev UT-2 (russian: Яковлев УТ-2; NATO reporting name "Mink") was a single-engine tandem two-seat low-wing monoplane that was the standard Soviet trainer during the Great Patriotic War. It was used by the Soviet Air Force from 1937 until replaced by the Yakovlev Yak-18 during the 1950s. Development The preceding U-2 (Po-2) biplane was no longer a suitable trainer for the faster modern aircraft entering service, and to fill the role, the UT-2 was designed as a trainer. The new aircraft was designed by Alexander Sergeevich Yakovlev's team at OKB-115. Originally designated AIR-10, it was based upon the AIR-9, but it was simpler, with tandem open cockpits, also omitting slats and flaps. It first flew on 11 July 1935. The AIR-10 won the competition in 1935 and, after minor changes, was accepted as the standard Soviet Air Force trainer. With the disgrace of Alexey Ivanovich Rykov under whom Yakovlev had been working, the initials ''AIR'' were replaced with ''Ya'' ...

Leading Edge Slats
Slats are aerodynamic surfaces on the leading edge of the wing of a fixed-wing aircraft which, when deployed, allow the wing to operate at a higher angle of attack. A higher coefficient of lift is produced as a result of angle of attack and speed, so by deploying slats an aircraft can fly at slower speeds, or take off and land in shorter distances. They are used during takeoff and landing or while performing low speed maneuvers which may take the aircraft close to a stall, they are retracted in normal flight to minimize drag. Slats are one high-lift device used on high speed turbojet aircraft, trailing edge flap systems running along the trailing edge of the wing are common on all aircraft. Types Types include: ;Automatic: The spring-loaded slat lies flush with the wing leading edge, held in place by the force of the air acting on them. As the aircraft slows down, the aerodynamic force is reduced and the springs extend the slats. Sometimes referred to as Handley-Page slat ...

Air Force Of The Polish Army
The Air Force of the Polish Army ( pl, Lotnictwo Wojska Polskiego), unofficially known as the People's Polish Air Force was the name of the Soviet-controlled Polish Air Force in the USSR between 1943 and 1947 created alongside the Polish People's Army ( pl, Ludowe Wojsko Polskie), a subordinate to the Red Army. It was the primary Polish air force formation within the Polish Armed Forces in the East during World War II. Formation Setting up the first combat unit – the 1st Independent Fighter Squadron (''1. Samodzielna Eskadra Lotnictwa Myśliwskiego'') – started on July 7, 1943. As of July 23, 1943, their first training airfield was Grigoryevskoye, about 15 km south of Moscow. On August 20, 1943, the Squadron was renamed as the Polish 1st Fighter Regiment, and on October 6, as the 1st Fighter Regiment "Warszawa" (''"Warsaw"''). On April 1, 1944, two more Polish units were formed at Grigorievskoye: the 2nd Bomber Regiment "Kraków" and the 103rd Independent Liaison Avi ...

Yakovlev UT-2M Dwg
The JSC A.S. Yakovlev Design Bureau (russian: ОАО Опытно-конструкторское бюро им. А.С. Яковлева) is a Russian aircraft designer and manufacturer (design office prefix Yak). Its head office is in Aeroport District, Northern Administrative Okrug, Moscow. Overview The bureau formed in 1934 under designer Alexander Sergeyevich Yakovlev as OKB-115 (the design bureau has its own production base at the facility No.115), but dates its birth from 12 May 1927, the day of maiden flight of the AIR-1 aircraft developed within the Department of Light Aircraft of GUAP (Head Agency of Aviation Industry) under the supervision of A.S. Yakovlev. During World War II Yakovlev designed and produced a famed line of fighter aircraft. Irkut acquired Yakovlev in April 2004.

Hungarian Air Force
The Hungarian Air Force ( hu, Magyar Légierő), is the air force branch of the Hungarian Defence Forces. The task of the current Hungarian Air Force is primarily defensive purposes. The flying units of the air force are organised into a single command; under the Air Command and Control Centre. History 1918 to pre–World War II Following the dissolution of the Austro-Hungarian Monarchy in 1918, a small air arm was established operating surviving aircraft from Hungarian factories and training schools. This air arm became the Hungarian Red Air Force under the short-lived Hungarian Soviet Republic, but was disbanded upon its downfall. World War II Under the Treaty of Trianon (1920), Hungary was forbidden from owning military aircraft. However, a secret air arm was gradually established under the cover of civilian flying clubs. During 1938, as a result of the Bled agreement, the existence of the Royal Hungarian Air Force ( hu, Magyar Királyi Honvéd Légierő (MKHL)), was ...

Polish Air Force
The Polish Air Force ( pl, Siły Powietrzne, , Air Forces) is the aerial warfare branch of the Polish Armed Forces. Until July 2004 it was officially known as ''Wojska Lotnicze i Obrony Powietrznej'' (). In 2014 it consisted of roughly 16,425 military personnel and about 475 aircraft, distributed among ten bases throughout Poland. The Polish Air Force can trace its origins to the second half of 1917 and was officially established in the months following the end of World War I in 1918. During the invasion of Poland by Nazi Germany in 1939, 70% of its aircraft were destroyed. Most pilots, after the Soviet invasion of Poland on September 17, escaped via Romania and Hungary to continue fighting throughout World War II in allied air forces, first in France, then in Britain, and later also the Soviet Union. History Origins Military aviation in Poland started even before the officially recognised date of regaining independence (11 November 1918). The very first independent units of th ...

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] |
Yak-18
The Yakovlev Yak-18 (russian: Яковлев Як-18; NATO reporting name Max) is a tandem two-seat military primary trainer aircraft manufactured in the Soviet Union. Originally powered by one 119 kW (160 hp) Shvetsov M-11FR-1 radial piston engine, it entered service in 1946. It was also produced in China as the Nanchang CJ-5. Design and development A member of the second generation of Russian aircraft designers, and best known for fighter designs, Alexander Sergeyevich Yakovlev always retained a light aircraft design section. In May 1945, Yakovlev initiated design of the Yak-18 two-seat primary trainer. He designed it to replace the earlier Yakovlev UT-2 and Yakovlev Yak-5 in service with the Soviet Air Forces and DOSAAF (Voluntary Society for Collaboration with the Army, Air Force and Navy, which sponsored aero clubs throughout the USSR). In 1944, an advanced version of the UT-2 had been built with many of the features of the new Yak-18. The new aircraft flew a yea ...

Vertical Stabilizer
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability). It is part of the aircraft empennage, specifically of its stabilizers. The vertical tail is typically mounted on top of the rear fuselage, with the horizontal stabilizers mounted on the side of the fuselage (a configuration termed "conventional tail"). Other configurations, such as T-tail or twin tail, are sometimes used instead. Vertical stabilizers have occasionally been used in motor sports, with for example in Le Mans Prototype racing. Function Principle The vertical tail of an aircraft typically consists of a fixed vertical stabilizer or fin on which a movable rudder is mounted. A trim tab may similarly be mounted on the rudder. Together, their role ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
