METHOD OF TAKING OFF AUXILIARY POWER FROM AN AIRPLANE TURBOJET, AND A TURBOJET FITTED TO IMPLEMENT SUCH A METHOD

摘要

Producing the electrical power need for equipment on board an airplane. Auxiliary power is taken off by means of a shaft driven by the high pressure turbine and, when idling, the efficiency of the low pressure turbine is degraded so as to enable the high pressure turbine to operate at a speed that is sufficient for delivering the required auxiliary power.
