jet propulsion

1. The driving of an aircraft by the powerful thrust developed when a jet of gas is forced out of a jet engine.

2. Propulsion by means of any fluid that is forced out in a stream in the opposite direction. Squids, octopuses, and cuttlefish, for example, jet their way through the ocean by taking in and then quickly expelling water.

Reaction propulsion in which the propulsion unit obtains oxygen from the air, as distinguished from rocket propulsion, in which the unit carries its own oxygen-producing material. In connection with aircraft propulsion, the term refers to a gasoline or other fuel turbine jet unit that discharges hot gas through a tail pipe and a nozzle which provides a thrust that propels the aircraft. See also rocket propulsion.
