jet propulsion

n.
Propulsion derived from the rearward expulsion of matter in a high-speed stream, especially propulsion by jet engines.

jet propulsion

n
1. (Aeronautics) propulsion by means of a jet of fluid
2. (Aeronautics) propulsion by means of a gas turbine, esp when the exhaust gases provide the propulsive thrust

jet′ propul′sion


n.
the propulsion of a body by its reaction to a force ejecting a gas or a liquid from it.
[1865–70]

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.

jet propulsion

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.

(dʒet) noun
1. a sudden, strong stream or flow (of liquid, gas, flame or steam), forced through a narrow opening. Firemen have to be trained to direct the jets from their hoses accurately.
2. a narrow opening in an apparatus through which a jet comes. This gas jet is blocked.

ˈjet-lag noun
symptoms such as tiredness and lack of concentration caused by flying a long distance in a short period of time.
ˌjet-proˈpelled adjective
driven by jet propulsion. jet-propelled racing-cars.
jet propulsion a method of producing very fast forward motion (for aircraft, missiles etc) by sucking air or liquid etc into a jet engine
and forcing it out from behind.
