摘要

The power supply device (10) has a removable stick (11). The stick includes an upper alternator (20) and an upper tube (12) secured to a rotor shaft (5) so as to be constrained in rotation with the rotor shaft. The upper alternator has upper coils (21) fastened to an upper inside peripheral surface of the upper tube. The stick has a rod (13) carrying an upper permanent magnet (22). A mechanism (30) allows the rod and the upper tube to move with distinct rotary movements. The mechanism has a connection member (31) so as to be connectable to a reference member of an aircraft.
