The aircraft was designed by Nikolai Polikarpov to replace the U-1 trainer (a copy of the British Avro 504), which was known as Avrushka to the Soviets. [6]The prototype of the U-2, powered by a 74 kW (99 hp) Shvetsov M-11 air-cooled five-cylinder radial engine, first flew on 7 January 1928 piloted by M.M. Gromov. [6]
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
On 2 May 1951, Skyraiders made the only aerial torpedo attack of the war, hitting the Hwacheon Dam, then controlled by North Korea. [13] On 16 June 1953, a USMC AD-4 from VMC-1 piloted by Major George H. Linnemeier and CWO Vernon S. Kramer shot down a Soviet-built Polikarpov Po-2 biplane, the only documented Skyraider air victory of the war. [14]
This is a list of aircraft shootdowns, dogfights and other incidents during wars since World War II.An aircraft shootdown occurs when an aircraft is struck by a projectile launched or fired from another aircraft or from the ground (anti-aircraft warfare) which causes the targeted aircraft to lose its ability to continue flying normally, and then subsequently crashing into land or sea, often ...
15x WV-2/EC-121K; 3x WV-2Q/EC-121M and 2x WV-3/WC-121N; Another unarmed EC-121M was destroyed in one-sided combat. In April 1969, North Korean Air Force MiG-21 fighter-interceptors shot down an EC-121 in international airspace off the country's east coast, killing all of the crew of 31 on board. [5]
Later sent to the US in October 1941, becoming the first jet engine to run in North America. W.1A Based on W.1, 1,450 lbf (6.45KN) air-cooled turbine disc and incorporating features intended for W.2. Used for second series of test flights of E.29/39 W4041/G beginning on 16 February 1942, and fitted with fuel barostat. Later featured modified ...
JetBlue Airways said a New York-bound flight from Haiti was struck by gunfire on the same day a Spirit Airlines plane was shot, forcing the company to temporarily halt all flights to the Caribbean ...
A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket , water jet , and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet , turbofan ...
