The invention belongs to the field of aircrafts, and discloses a propeller blowing wing lift augmentation type multi-wing aircraft and a control method thereof.The propeller blowing wing lift augmentation type multi-wing aircraft comprises a fuselage, wings, a control system and a forward pulling propeller, the wings are arranged in multiple rows, and each row of wings is composed of a left wing and a right wing which are symmetrically distributed on the two sides of the fuselage; the multiple rows of wings are symmetrically arranged on the fuselage along the axis of the fuselage according to the gravity center moment of the aircraft; the plurality of front pull propellers are arranged at the front lower part of the wing, and the center line of a propeller disc of each front pull propeller and the chord of the wing are arranged at an attack angle of an included angle alpha; the control system is used for controlling the control quantity of each control surface of the aircraft and the rotating speed and steering of the forward-pulling propeller. High-speed airflow blown by the forward pulling propellers flows to the wings at an attack angle alpha, and generates a pneumatic coupling lift augmentation effect with the wings to generate forward and upward pulling forces on the aircraft; the rotating speed of the front pull propellers on the front-row wings is increased through control of the control system, the fuselage tilts backwards by theta to raise the head, the rotating speed of the front pull motors and the lowering angles of the flaps and the ailerons are controlled through the control system, force borne by the aircraft in all directions is balanced to achieve hovering, and resultant force is made to be vertically upward to achieve vertical take-off. The resultant force is vertically downward to realize vertical landing, and the resultant force is forward to realize level flight cruise.
本发明属飞行器领域,公开了一种螺旋桨吹翼增升式多翼飞行器及其控制方法,包括机身、机翼、操控系统以及前拉螺旋桨,机翼包含多排,每排机翼由对称分布在机身两侧的左右机翼构成;多排机翼沿机身轴线按飞行器重心力矩对称方式布置在机身上;所述前拉螺旋桨为多个,各个前拉螺旋桨安装在机翼前下方,前拉螺旋桨的桨盘中心线与机翼翼弦成夹角α的迎角布置;操控系统用于控制飞行器各舵面舵量和前拉螺旋桨转速及转向。前拉螺旋桨吹出的高速气流以迎角α流向机翼,与机翼产生气动耦合增升效应,对飞行器产生向前和向上的拉力;通过操控系统控制增加前排机翼上的前拉螺旋桨的转速,使机身向后倾转θ抬头,通过操控系统控制各前拉电机转速和襟翼、副翼的下放角度,使飞行器所受各向力平衡以实现悬停,使合力垂直向上实现垂直起飞,使合力垂直向下实现垂直降落,使合力向前实现平飞巡航。
