A pulse jet engine is a category of jet engine in which combustion occurs in pulses. Pulsejet engines can be made with few or no moving parts, and are proficient of running statically. Pulse jet engines are a lightweight form of jet propulsion, but usually have a reduced compression ratio, and hence give a low specific impulse. One notable line of research of pulsejet engines includes the pulse detonation engine which involves repeated blowing up in the engine, and which can potentially give high solidity and good efficiency. They were invented in the early 1900′s, and were cutting edge science until after WWII. Pulsejets got deserted, many feel long before they even reached their prime .They went from being the main source of power for tens of thousands of journey missiles. In we are mean a pulse jet engine and planned to analyse it for the rationale of get a high performance into it.
