    • PROBLEM TO BE SOLVED: To regulate a turbojet having no defect of a conventional technology, with a high pressure spool, a low pressure spool for driving a fan arranged in a fixed casing and a generator including a rotor arranged in the fan, taking out motive power from there and incorporated into the fan.
      SOLUTION: This turbojet has the high pressure spool 30 and the low pressure spool 20 driving the fan 40. For making electricity, the turbojet further includes the generator 60 arranged in the fan 40 and taking out the motive power from there. The generator has the rotor 62 incorporated into the fan and a stator 64 incorporated into a fan casing 14. Such arrangement of the generator 60 avoids the operational problem of an engine at a low speed, and enables mechanical power to be highly efficiently converted into electric power. Installation and maintenance of the generator are further easily performed by embedding the generator in the fan 40.
