The invention relates to an aircraft propulsion assembly and an aircraft comprising such a propulsion assembly. The aircraft propulsion assembly is equipped with at least one ventilation device (52) configured to cool at least one region of the propulsion assembly. The ventilation device is adjustable and comprises: at least one ventilation hole (54) into the area to be cooled; at least one valve (56) movable between a closed position, in which the valve (56) closes the vent hole (54), and an open position, in which the valve (56) at least partially releases the vent hole (54); at least one thermoelectric generator (64) configured to generate a current; and at least one automatic control mechanism configured to control the position of the valve 56 by using the current generated by the thermoelectric generator (64). This solution makes it possible to adjust the bleed air flow in accordance with the cooling demand.

    本发明涉及飞行器推进组件及包括这种推进组件的飞行器。飞行器推进组件配备有被配置成冷却推进组件的至少一个区域的至少一个通风装置(52)。该通风装置是可调节的并且包括:至少一个通风孔(54),其进入要冷却的区域;至少一个阀(56),其能够在关闭位置与打开位置之间移动,在关闭位置,阀(56)关闭通风孔(54),在打开位置,阀(56)至少部分地释放通风孔(54);至少一个热电发电机(64),其被配置成产生电流;以及至少一个自动控制机构,其被配置成通过使用由热电发电机(64)产生的电流来控制阀56的位置。该解决方案使得可以根据冷却需求来调节泄放空气流量。
