姿控发动机多通道推力测试试验台及多通道推力标定方法
By designing a multi-channel thrust test rig and utilizing the correspondence between the moving frame and the pressure sensor, thrust tests for pitch, yaw, and roll channels can be completed on the same test rig. This solves the problems of long test cycles and large errors in traditional single-channel test rigs, and improves test efficiency and accuracy.

Abstract
本申请涉及姿控发动机多通道推力测试试验台及多通道推力标定方法,姿控发动机多通道推力测试试验台通过动架安装发动机标定模拟件，发动机标定模拟件经十字标定板划分为四个象限区域且每个区域设两个标定加载点，八个标定加载点位于同一水平面且到中心垂直距离相等，试验台与动架间的八个压力传感器与八个标定加载点一一对应且测力方向与加载方向一致，上述结构使试验台可通过在不同标定加载点施加力，利用对应压力传感器同时或分别采集俯仰、偏航、滚转三个通道的力信号，无需在不同单通道试验台间拆装发动机即可完成多通道推力测试，减少了试验次数，缩短了试验周期，且避免了多次安装带来的额外偏差，提升了测试效率与准确性。
