A pulse jet engine (or pulsejet) is a type of jet engine in which combustion occurs in pulses. Pulsejet engines can be made with few or no moving parts, and are capable of running statically.
Pulse jet engines are a lightweight form of jet propulsion, but usually have a poor 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 detonations in the engine, and which can potentially give high compression and good efficiency.

Famous quotes containing the words pulse, jet and/or engine:
“While our pulse beats and we feel emotion, let us put off the business. Things will truly seem different to us when we have quieted and cooled down. It is passion that is in command at first, it is passion that speaks, it is not we ourselves.”
—Michel de Montaigne (1533–1592)
“But every jet of chaos which threatens to exterminate us is convertible by intellect into wholesome force. Fate is unpenetrated causes.”
