GAS TURBINES AND JET ENGINES
Both engine types used heated pre-compressed air in combustion chambers. Then this air streams through a turbine. The turbine shaft is connected with an air compressor. Gas turbines also are used with a group to be driven, e.g. with a generator, a pump or the rotor blades of a helicopter. In a jet engine, the turbine only drives the compressor and a few auxiliary aggregates. The desired effect, i.e. the propulsion of an aircraft without propellers, is achieved by the recoil effect of the combustion gases streaming out of a propelling nozzle. The development of the gas turbine, which made only slow progress until the 1940s, was accelerated by the rapid wartime development of jet engines.

Jet turbine engine Jumo
004 B, of 1944
The development of the 004 jet engine started in 1939. When the Jumo 004 B
went into production at the end of 1943, this marked the beginning of
large-scale series production of jet engines.
