Jet engine that derives its thrust from a jet of hot exhaust gases. Pure turbojets can be very powerful but use a lot of fuel.

A single-shaft turbojet consists of a shaft (rotor) rotating in a casing. At the front is a multiblade compressor, which takes in and compresses air and delivers it to one or more combustion chambers. Fuel (kerosene) is then sprayed in and ignited. The hot gases expand through a nozzle at the rear of the engine after spinning a turbine. The turbine drives the compressor. Reaction to the backward stream of gases produces a forward propulsive thrust.

The blue and white triband is based on the flag of the Central American Federation (CAF), a grouping of African states imposed by the British government in 1953. The stars represent the Federation's five original members. Effective date: 18 January 1949. >>
