A PWC or Jet Ski has a water Jet propulsion system. With this system the Jet drive is used for propulsion and steering. Jet drives dont turn without using the throttle unless moving very slow and even then it is limited.
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.
A glider has no propulsion system. If it were jet propelled it would be called a jet plane.
Jet Propulsion Laboratory was created in 1930.
by using jet propulsion
The water jet is a means of propulsion.

It is a name, the name of a character in a Shakespeare play called King Lear or the maker of an airplane called a Lear Jet.
