Best Answer

Propulsion is a force that causes movement. The force can be caused by either a differential pressure, or a differential momentum (Newton's second law).

In the case of a jet engine, the exhaust velocities are much higher than the inlet velocities, causing a momentum thrust

The word is derived from two Latin words: promeaning before or forwards and pellere meaning to drive. Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction. A gas, or working fluid , is accelerated by the engine, and the reaction to this acceleration produces a force on the engine.

  • nuclear powered submarines
  • nuclear powered ships
  • nuclear powered jet aircraft
  • nuclear powered rockets
  • nuclear powered helicopter
  • nuclear powered trains
  • nuclear powered cars
  • nuclear powered motorcycles
  • etc.

Basically any vehicle propelled by nuclear reactor, some more practical than others.

In the simplest terms, the nuclear reaction generates heat, which is used to generate steam, which turns a turbine that is geared to the propeller.
