The invention relates to a ducted wing aircraft capable of taking off and landing vertically. The aircraft is characterized in that a thrust-lift combined generator is formed by a duct, propellers and one or more wings in the airflow of the ducted propellers, the axis of the aircraft body and the axis of the duct form a larger intersection angle with the ground during takeoff, so as to balance the gravity of the aircraft body with the combined force of thrust and lift, the thrust of the propellers and the lift of the duct and the wings are generated at the same time, the duct has a large gain effect on the thrust and the lift, and therefore it is guaranteed that the vertical take-off and landing purpose is achieved with small installed power. The invention has the advantages that the characteristic that a common aircraft capable of taking off and landing vertically does not need an airport can be kept, and the aircraft has the advantages of small take-off power, long endurance, low purchase cost, capability of safely flying at a low speed and a large angle of attack and the like.
本发明涉及可垂直起阵的涵道翼飞机,其特征是由涵道、螺旋桨和处于涵道螺旋桨气流内的一个或多个机翼构成推力‑升力组合发生体,起飞时机身和涵道轴线对地面有较大交角,以便将推力、升力的合力去平衡机体的重力:螺旋桨的推力和涵道、机翼升力实现同时刻发生,且涵道对推力和升力均有较大增益效果,从而保证以较小装机功率达到垂直起降目的。本发明的优点是既可保持一般可垂直起阵飞机不需要机场的特点,又具备起飞功率小,航时长,购置费用省,可在低速和大迎角下安全飞行等长处。
