The invention belongs to a test flight test technology, and particularly relates to a helicopter transition speed reducer power loss measuring method. Input and output power is obtained by measuring input and output torque of the transition speed reducer, and accurate measurement of power loss of the transition speed reducer in the ground test process is achieved. The device is simple and practical, is low in processing and maintenance cost, can effectively and accurately measure the torque value of the output shaft of the transition speed reducer in a non-contact manner, is applied to the helicopter test flight test process, can guarantee the effective matching of the output of the helicopter engine power and the output power of the transition speed reducer, and guarantees the normal operation of the helicopter.

    本发明属于试验试飞测试技术,具体涉及一种直升机过渡减速器功率损失测量方法;通过测量过渡减速器输入、输出扭矩,获得输入、输出功率,解决地面试验过程中过渡减速器功率损失的精确测量。本发明简单实用,加工及维护成本较低,能够有效的精确的非接触式测量过渡减速器输出轴扭矩数值,应用于直升机试验试飞过程,能够保障直升机发动机功率的输出与过渡减速器输出功率的有效匹配,保障直升机的正常运转。
