The invention relates to an automatic control method for the rotating speed of a propeller, and the method comprises the steps: calculating the opening degree of an air throttle, and determining the opening degree interval of the air throttle; according to the corresponding relation between the opening degree interval of the air throttle and the target rotating speed of the propeller, calculating the current target rotating speed needed by the propeller; generating a rotating speed control signal according to the calculated current target rotating speed, and sending the rotating speed control signal to a propeller controller; and enabling the propeller controller to control the rotating speed of the propeller to be adjusted to the current target rotating speed. According to the automatic control method, the rotating speed of the propeller can be automatically adjusted according to the opening degree of the throttle, so that the aircraft can ensure that the working efficiency of the propeller is within the optimal range under different flight working conditions.

    本发明涉及一种螺旋桨转速的自动控制方法,该自动控制方法包括:计算节风门的开度,确定节风门的开度区间;根据节风门的开度区间与螺旋桨的目标转速之间的对应关系,计算螺旋桨所需的当前目标转速;根据计算的当前目标转速,生成转速控制信号,并将转速控制信号发送到螺旋桨控制器;螺旋桨控制器控制螺旋桨的转速调节至当前目标转速。上述自动控制方法能够根据节风门的开度自动调节螺旋桨的转速,使飞行器在不同飞行工况下均能保证螺旋桨的工作效率处于最佳范围内。
