    The compressed air inside the engine is heated and expands rapidly. The pressure of the hot gas increases. It is directed by the engine chamber to the exhaust opening at the rear of the engine.

    In fact, a jet engine is a form of gas turbine. It consists of a compressor at the front part which draws air in. Because of the action of the compressor, air only can flow in one direction.

    You may refer to the following web-pages for the structure and operation of jet engines:
