jet propulsion
- Definição1
- A form of propulsion where a mass of air is accelerated through a large change in velocity, and the body is propelled forward as a result of the action-reaction phenomenon, or Newton's third law of motion. The propulsion unit obtains its oxygen from the air for imparting a higher velocity to the incoming gases by combusting fuel. The thrust is obtained by expelling a mass air flow at a higher velocity than its incoming velocity.
- Definição2
- (a) The propulsion of a rocket or other craft by means of reaction engine.
- Spanish
- propulsión a chorro
