Crossword clues for pulsejet


n. a valved jet engine where combustion occurs in pulses, as used in the V-1 flying bomb


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 or no moving parts, and is capable of running statically (i.e. it does not need to have air forced into its inlet typically by forward motion).

Pulsejet 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.

Usage examples of "pulsejet".

The ferry shifted to pulsejet mode as soon as the initial blast lifted it from the pad.

Though they could hear the distant thunder of pulsejets, the sky was clear of buzz bombs.

A pulsejet develops thrust at rest, and could boost a vehicle to high subsonic velocity where ramjets become efficient.
