The invention discloses an aircraft non-stall floating lift airfoil of an implementation method thereof. The non-stall floating lift airfoil comprises a floating lift airfoil body, a connecting rotating shaft and an attack angle adjusting control surface, wherein the floating lift airfoil body is an independent floating lift airfoil with an attack angle and is used for generating aerodynamic liftrequired by an aircraft, and the aerodynamic attack angle is independent of a pitching attitude angle of a fuselage; the connecting rotating shaft is used for connecting the floating lift airfoil andthe fuselage; the pitch angles of the floating lift airfoil and the fuselage are mutually independent; and the floating lift airfoil can freely rotate around the connecting rotating shaft relative tothe fuselage in a pitching mode; the attack angle adjusting control surface is used for adjusting the flight attack angle of the floating lift airfoil, so that the floating lift airfoil is stabilizedat a set attack angle, and the airfoil is prevented from stalling in the flight process. When the aircraft flies, the attack angle of the floating wing is only related to the flight speed direction, the lift force of the aircraft is adjusted by adjusting the attack angle adjusting control surface, and the attack angle of the floating wing is adaptively balanced on the attack angle set by the attack angle adjusting control surface.

    本发明公开了一种飞行器不失速浮动升力翼面及其实现方法。该不失速浮动升力翼面包括浮动升力翼面、连接转轴、攻角调节舵面,其中浮动升力翼面为攻角独立浮动的升力翼面,用于产生飞行器所需的气动升力,且气动攻角与机身俯仰姿态角相互独立;连接转轴用于连接浮动升力翼面与机身,浮动升力翼面和机身的俯仰角相互独立,浮动升力翼面能够绕连接转轴相对于机身俯仰自由转动;攻角调节舵面用于调节浮动升力翼面的飞行攻角,实现浮动升力翼面稳定在设定攻角,保证飞行过程中翼面不失速。飞行器飞行时,浮动机翼的攻角只与飞行速度方向有关,通过调节攻角调节舵面实现飞行器升力大小的调节,并且浮动机翼攻角自适应平衡在攻角调节舵面所设定的攻角上。
