The General Electric CF6 commercial engine became a development of the General Electric TF39 engine. Its first launch took place in 1971. It was used as a drive for B747, B767, DC-10, A300, A310, A330 and others. The entire family of CF6 engines was created, from which subsequent generations of turbo-fan engines developed.

The Pratt & Whitney F-100 engine used in the F-15 and F-16 aircraft was a great success in military aviation. In 1962, the research and development work of the USAF and NAVA were merged. The goal was to cut costs. As a result, in 1967, USAF and NAVY issued joint requirements for a new engine…

Atar 9 engine data: The single-flow, single-shaft motor received a 9-stage axial compressor. Compressor 5.2: 1 compression. Combustion chamber. 2-stage turbine. Afterburner. Length 5.90 m, diameter 1.00 m, weight 1,456 kg. 42.00 kN draft without afterburning and 58.90 kN with afterburning. Air flow through the engine 68 kg / s. fuel consumption 103 kg /…

The JT3D / TF33 engine is a development of the JT3C / J57 engine by making it in the two-flow technology. The engine was developed by the airlines for the B 707 aircraft. Work on it started in 1957. The first operational use of the propulsion took place on June 22, 1960, when the first…

Aleksander Mikulin developed the AM-5 engine. The AM-5 engine was created in 1951 and was a scaled down AM-3 engine. The power, as well as dimensions and weight were reduced, which allowed to place this engine in a fighter class airframe. Alexander Mikulin’s team worked under time pressure. The lag of CCCP in turbojet engines…

Argus As 109-014 was the pulse engine that powered the V1 flying bombs. The V1 bomb was a small unmanned aircraft that was automatically controlled by a simple gyroscopic autopilot. The warhead had a mass of 850 kg. Range about 250 km. Cruising speed about 640 km/h. The engine, with a thrust of 2.7 kN…

Airplane jet propulsion is a colloquial term currently used to indicate that we mean a turbojet powered airplane. Although there is a much larger range of jet propellers. A jet engine is a rocket engine and a pulse engine, and modern airplanes do not have such. I will try to explain why this happened.

Star engines, developed by Polish constructors, did not meet most of the needs of Polish Aviation. We had talented designers, but we lacked the technical background, and most of all, the funds. Remember that developing a good aircraft engine takes a long time (4-6 years) and requires a lot of testing. Significant involvement of the…

Star engines, classic ones, became the main tool of aviation development. However, at present they are already historical structures. They are still in production but are not being developed anymore. An example of the still produced engine is the WSK PZL Kalisz ASz-62 engine with a capacity of 1,000 HP. These engines have already been…

"When I entered the Ministry of Defense, the Armed Forces of the Republic of Poland did not have the ability to ensure the security of the state’s territory, airspace, key state management facilities, or cyberspace," Minister Antoni Macierewicz said in the Sejm on Wednesday, presenting information on the audit at the Ministry of National Defense.
