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 (s), fan jet (noun), turbofans (pl)
1. A jet engine in which fans driven by a turbine force air into the exhaust gases, thereby increasing the propelling thrust of the engine.
2. A jet aircraft that has turbofan 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 gas turbine which utilizes a compressor, combustion chamber, and turbine; with the turbine drawing just enough energy from the gas flow to drive the compressor.
2. A jet engine with a gas turbine that uses exhaust gases to provide the propulsive thrust for an aircraft.

An aircraft employing such an engine; the earliest form of jet aircraft in the late 1930s.
