A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in pulses.A pulsejet engine can be made with few [1] or no moving parts, [2] [3] [4] and is capable of running statically (that is, it does not need to have air forced into its inlet, typically by forward motion).
A pulsejet engine is an air-breathing reaction engine that employs an ongoing sequence of discrete combustion events rather than one sustained combustion event. This clearly distinguishes it from other reaction engine types such as rockets, turbojets, and ramjets, which are all constant combustion devices.
The Argus As 014 (designated 109-014 by the RLM) was a pulsejet engine used on the German V-1 flying bomb of World War II, and the first model of pulsejet engine placed in mass production. License manufacture of the As 014 was carried out in Japan in the latter stages of World War II , as the Kawanishi Maru Ka10 for the Kawanishi Baika kamikaze ...
The Ka10 was far less complex than contemporary turbojet or piston engines and the intention was for the pulsejets to be built by unskilled or semi-skilled laborers in small workshops. During the design stage concerns were expressed due to the relatively short engine lifespan and the high noise of the pulsejet engine which could give advance ...
Valveless pulse jet engines are insensitive to sand and small debris. The engine's thrust augmenters can be incorporated as load bearing structures in the aircraft's superstructure, thus reducing overall weight. The design features no moving parts, which the creators claim increases reliability compared to conventional engines with moving parts.
The basic operation of the PDE is similar to that of the pulse jet engine. In the pulse jet, air is mixed with fuel to create a flammable mixture that is then ignited in an open chamber. The resulting combustion greatly increases the pressure of the mixture to approximately 100 atmospheres (10 MPa), [8] which then expands through a nozzle for ...
It was an innovative design that used a pulse-jet engine, while previous work dating back to 1915 by Sperry Gyroscope relied on propellers. While employed by the Argus Motoren company, Fritz Gosslau developed a remote-controlled target drone , the FZG 43 ( Flakzielgerät-43 ).
The Messerschmitt Me 328 was a prototype pulsejet-powered fighter aircraft designed and produced by the German aircraft manufacturer Messerschmitt AG.. The Me 328 arose out of design studies for the P.1079 in 1941, having been envisioned as a parasite aircraft that would protect Luftwaffe bomber formations from Allied fighter aircraft.
