reaction engine

[rē′ak·shən ‚en·jən]
(aerospace engineering)
An engine that develops thrust by its reaction to a substance ejected from it; specifically, such an engine that ejects a jet or stream of gases created by the addition of energy to the gases in the engine. Also known as reaction motor.

Principle of reaction engine.
An engine that works on the principle of Newton's third law of motion: To every action, there is an equal and opposite reaction. All aerospace propulsions are based on this principle.
