The pulse jet engine was used by the Germans in WWII, the infamous doodle-bug. It is a pretty noisy engine, but simple and powerful.
Jet engine principles have been known since antiquity. In UK jet engines were invented by Frank Whittle in the mid 1930s, - this was the turbojet.
In more recent times, simple gas jets have been used as personal propulsion, but not with wide acceptance.
And in a fluid medium, the Jet Boat propulsion system invented by Bill Hamilton of New Zealand, though he was always at pains to deny this and point to Archimedes as the original inventor. Nevertheless, his work is the first practical application of the principle.
The mighty rocket engines used to lift payloads into space are essentially jet engines.

because jet engines reqire air to take in in order to work, rocket engines spew matter to privide thrust
Frank Whittle was the invetor of the jet engine.

A jet engine uses fuel from the aircraft's fuel tanks, but gets its oxidizer from oxygen in the air. So it won't work in space, where there is no air. A similar engine that carried its own oxygen would be called a "rocket", and WOULD work in space - because it wouldn't need air.
Jet fuel is sprayed into the exhaust gas steam and ignited, as this happens, the end of the primary nozzle constricts hydraulically and the result is increased thrust as the jet exhaust is "after burned".
The Germans invented the first operational jet engine during WW2.

The combustion of the jet fuel in the engine of a jet aircraft propells the craft forward when it exits the nozzles of the jet engine(s) at high speed.
A mechanical device that can work by means of fuel consumption. A mechanical device that can work by means of fuel consumption.
It depends on the engine. The weight of the jet engine varies from 542lbs to 13842lbs.
