The invention discloses a resistance reduction structure and method for a tilt-rotor aircraft. The resistance reduction structure comprises a fixed section wing, a tilt section wing, an aileron, a trailing edge blowing mechanism, a fairing, a motor nacelle, a propeller, a steering engine, a driving gear, a driven gear and a tilt shaft, and the trailing edge blowing mechanism comprises a high-pressure air chamber, a rotating shaft and a shifting piece; when the aircraft is in a helicopter mode, the trailing edge blowing mechanism blows air from the trailing edges of the tilting wings to the leading edges to separate airfoil airflows on the tilting wings, so that the resistance generated by high-speed airflows of propellers on the tilting section wings is reduced, and the tilting wing aircraft is more stable in hovering and taking-off and landing; the advantages of a helicopter aircraft and a fixed-wing aircraft are effectively combined, vertical take-off and landing and high-efficiency cruising speed can be achieved, and the problem that extra resistance is generated by a tilt-rotor aircraft in a helicopter mode is solved.
本发明公开了一种倾转翼飞行器减阻结构及方法,所述减阻结构包括固定段机翼、倾转段机翼、副翼、后缘吹气机构、整流罩、电机短舱、螺旋桨、舵机、主动齿轮、从动齿轮、倾转轴,后缘吹气机构包括高压气室、旋转轴、拨片;飞行器处于直升机模式时后缘吹气机构会从倾转翼后缘向前缘吹气使倾转翼上翼面气流分离,以减小螺旋桨的高速气流在倾转段机翼上产生的阻力,从而使倾转翼飞行器悬停起降更加稳定;本发明有效结合直升机飞行器和固定翼飞行器的优点,既可实现垂直起降和较高效的巡航速度,又解决了倾转翼飞行器在直升机模式下产生的额外阻力问题。
