Related to Turbojets: Jet turbine
1. A jet engine having a turbine-driven compressor and developing thrust from the exhaust of hot gases.
2. An aircraft in which a turbojet is used.
1. (Aeronautics) short for turbojet engine
2. (Aeronautics) an aircraft powered by one or more turbojet engines
2. an airplane equipped with one or more turbojet engines.
1. A jet engine in which the exhaust gas operates a turbine that in turn drives a compressor that forces air into the intake of the engine.
2. An aircraft powered by an engine or engines of this type.
Did You Know? Fully loaded, a jumbo-sized airliner weighs nearly 800,000 pounds. Yet its turbojet engines are so powerful that it hurtles down the runway fast enough to lift it into air and climb to 35,000 feet. Where does this power come from? From the movement of air itself. Every turbojet has a compressor, a series of small rotating fan blades. These blades draw in air and pressurize it, driving it back into a combustion chamber where a fuel (such as kerosene) is injected and ignited. The burning of the fuel causes the air to expand, adding to the already high pressure and causing the mixture of hot air and gas to rush over turbines with enormous speed. This causes the turbine blades to turn, and they spin a drive shaft that rotates the compressor fans. The hot pressurized air then blasts out the rear opening of the engine, forcing the plane forward. Most turbojet engines today are turbofans and have a large fan at the front that is turned by one of the turbines. Every second, the fan sucks in enough air to empty an average-sized house, adding to the volume and pressure of the air rotating the turbines and providing forward thrust.
A jet engine whose air is supplied by a turbine-driven compressor, the turbine being activated by exhaust gases.
