The invention discloses a takeoff control method for an unmanned gyroplane. The takeoff control method is used for takeoff of the unmanned gyroplane. When the unmanned gyroplane takes off, an engine drives rotor wings to rotate to a preset rotating speed through a pre-rotating mechanism, the pre-rotating mechanism is rapidly disconnected, a propeller disc inclines backwards to the maximum angle, abrake is loosened, an engine accelerator is opened to the maximum degree, skating is started, the backward inclination angle of the propeller disc is kept during skating till a front wheel is lifted,after the pitch angle of a fuselage is larger than a preset value, the backward inclination angle of the propeller disc is rapidly reduced to a preset value and adjusted within a certain range according to the attitude angle and the lifting speed of the fuselage, climbing is started after a certain period of time and when the airspeed and the height are greater than the preset value, takeoff endsafter the height exceeds the preset height, the unmanned gyroplane enters a climbing mode, and accesses flight path control.
本发明一种无人自转旋翼机起飞控制方法,用于无人自转旋翼机起飞。无人自转旋翼机起飞时,发动机通过预转机构驱动旋翼转动至预定转速,预转机构快速断开,桨盘后倾至最大角度,刹车松开,发动机油门开启至最大,开始滑跑,滑跑中保持桨盘后倾角度直至前轮抬起,机身俯仰角大于预定值后,迅速减小桨盘后倾角度至预定值,并根据机身姿态角及升降速度在一定范围内调整,一定时间后,空速、高度大于预定值后开始爬升,高度超过预定高度后,起飞结束,进入爬升模态,并接入航迹控制。
