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:
“Give him the darkest inch your shelf allows,
Hide him in lonely garrets, if you will,
But his hard, human pulse is throbbing still
With the sure strength that fearless truth endows.”
—Edwin Arlington Robinson (18691935)
“But every jet of chaos which threatens to exterminate us is convertible by intellect into wholesome force. Fate is unpenetrated causes.”
—Ralph Waldo Emerson (18031882)
“The machine unmakes the man. Now that the machine is perfect, the engineer is nobody. Every new step in improving the engine restricts one more act of the engineer,unteaches him.”
—Ralph Waldo Emerson (18031882)
