Abstract
An aircraft system is provided that includes a propulsor rotor, a powerplant, a cooling system, an anti-icing system and an aircraft structure. The powerplant is operatively and rotatably coupled to the propulsor rotor. The cooling system includes a cooling circuit and an air duct. The cooling circuit is thermally coupled with the powerplant to extract heat energy from the powerplant. The cooling circuit is thermally coupled with air flowing within the air duct to transfer the heat energy into the air and provide heated air. The anti-icing system includes an inlet fluidly coupled with the air duct. The anti-icing system is adapted to bleed some of the heated air from the air duct through the inlet to provide bleed air. The aircraft structure includes an exterior surface. The anti-icing system is adapted to direct the bleed air into the aircraft structure to heat the exterior surface.
