The invention discloses an electric propulsion rotorcraft power system and a control method thereof. The rotorcraft power system comprises a fusion energy storage system, a brushless direct current motor speed regulator, a brushless direct current motor, a propeller mounted on the brushless direct current motor, a flight control computer, an aircraft inertia sensor, a height sensor and a remote control signal receiver. The rotorcraft power system can predict the power demand of the rotorcraft so as to better manage the power output of the energy storage system. By means of the power system control method, the real-time power requirement and the power reserve requirement of the rotorcraft can be met through the power system with lower weight, meanwhile, the service life of an energy systemcan be prolonged through the power system control method, and the safety, maneuverability and cruising ability of the rotorcraft are improved.

    一种电推进旋翼飞行器动力系统及其控制方法,所述的飞行器动力系统包括融合储能系统、无刷直流电机调速器、无刷直流电机、安装在所述无刷直流电机上的螺旋桨、飞控计算机、飞行器惯性传感器、高度传感器以及遥控信号接收器。本发明飞行器动力系统能够预测飞行器功率需求,以达到较好的管理储能系统的功率输出。通过该动力系统控制方法,能够以更低重量的动力系统满足飞行器实时功率需求和功率储备需求,同时,该动力系统控制方法还能延长能源系统使用寿命,使得飞行器安全性、机动性和续航能力提高。
