Jet Propulsion Laboratory was created in 1930.
Impeller jet propulsion.
by using jet propulsion
Jet Propulsion Laboratory Display Information System was created in 1973.
The water jet is a means of propulsion.
The propulsion system of a biplane would be a piston engine driving a propellor, while a fighter jet is jet propelled.
No - Jet propulsion is not needed for the fact that it would suffer from retreating blade stall because of the lack of rotor rpms. They will have to figure out how to get better rpms prior to tackling jet propulsion. They have jet powered helicopters however they are still driven by the rotor system - not pushed by a jet.
in 1930's
Jet propulsion improved airplane flights. Before that piston engines were used. They were much slower compared to the jet engine.

Plasma [propulsion works like a jet with ions for the gas or matter pushed out.
