jet-, -ject, -jecting, -jected, -jection, -jector, -jectory; jacu-, jac-

(Latin: throw, send, fling, hurl, cast; gush; spurt)

A jet aircraft; especially, a large one, capable of supersonic flight.
1. A jet of heated gases ejected from a jet engine to provide thrust.
2. A thermal jet engine.
traject (verb), trajects; trajected; trajecting
1. To transport (move people or things), transmit (send from one person to another one), or transpose (change the order or position).
2. Etymology: from Latin trajectus; past participle of tracere, "to cast, to throw over" or "to throw across"; from tra-, a variant of trans- + -jec-, a combining form of jacere, " to throw".
1. The high curving line or path in which a moving object; such as, a missile travels through the air or space under the action of given forces including thrust, wind, and gravity.
2. The way in which a process or event develops over a period of time representing the long-term behavior of a procedure.
3. The path followed by a seismic wave as during an earthquake.
turbofan, fan-jet (s) (noun); turbofans; fan-jets (pl)
1. A jet engine in which fans driven by a turbine force air into the exhaust gases: A turbofan in such an aircraft increases the propelling thrust of the engine.
2. A jet aircraft that has turbofan engines: A fan-jet is an aircraft that is powered by one or even more jet engines.

A type of gas turbine in which the fan driving air into a turbojet also forces additional air around the outside of the turbine, combining it with the exhaust of the turbojet to provide thrust.

Turbofans are quieter than simple turbojets and somewhat more fuel efficient, and are widely used in commercial aircraft.

turbojet (s) (noun), turbojets (pl)
1. A jet engine propelled by the simplest form of a gas turbine: Turbojets utilize a compressor, combustion chamber, and turbine in which the turbine draws just enough energy from the gas flow to drive the compressor.

A jet engine with a gas turbine uses exhaust gases to provide the propulsive thrust for an aircraft.
2. An aircraft employing an engine propelled by a gas turbine: The earliest form turbojets were developed in the late 1930s.
