Abstract:
1. An electric power generating device for a rotor of a propfan-type of aircraft propulsion unit, the propulsion unit including a turbomachine rotating at least one rotor including a plurality of blades, an outer skin of the propulsion unit being subjected to atmospheric conditions outside the propulsion unit, the turbomachine generating a flow of hot gases that are released through a hot annular channel, the device for generating electrical power comprising: an annular crown that moves with the blades, an outer wall of the annular crown forming part of the outer skin of the propulsion unit and inner wall of the annular crown defining a portion of the hot annular channel; and means for transforming thermal energy into electrical energy, positioned between the inner wall and the outer wall of the annular crown, the means for transforming thermal energy extending in an annular fashion around all of the inner wall of the annular crown and over a predetermined width.
