More Information
Summary:The invention discloses a lifting force generation device and method based on acceleration of air circulation flow by a cross flow fan. The lifting force generation has no need for any relative motionof an aircraft itself and the ground or still air, and vertical take-off and landing of the aircraft can be realized. The device includes: a cross flow fan disposed on a wing and a return pipeline arranged below the wing. The return pipeline is an enclosed annular pipeline structure with an open upper end and closed periphery, and wraps the wing, an annular channel with an open upper end is formed between the wing and the return pipeline, and the cross flow fan is located at the opening position of the annular channel. At the opening position of the annular channel, an air inlet and an air outlet are respectively formed between the aerofoils on both sides of the cross flow fan and the opening of the return pipeline, and suction surfaces are formed on the aerofoils respectively. 本发明公开了种基于横流扇加速空气循环流动的升力产生的装置及方法，升力的
