Air entraining control method for APU with loaded air compressor

The invention discloses an air entraining control method for an APU with a loaded air compressor. The air entraining control method comprises the following steps that S100, measurement parameters are obtained through an electronic controller; s200, judging whether the aircraft works on the ground or not to select a corresponding target rotating speed; s300, the working number of air conditioner bags is obtained, a single air conditioner bag is selected for air entraining, the aircraft is located on the ground, and the angle of a guide vane is adjusted to a first target angle according to the obtained target rotating speed, the first flight height and the first air inlet temperature; the aircraft leaves the ground, the target rotating speed is set to be 100%, and the guide vane angle is adjusted to a second target angle according to the second flight height and the second air inlet temperature; selecting double air-conditioning bags to bleed air, and adjusting the angle of the guide vane to a third target angl
