| 中文摘要: |
| 为了研究飞行过载和推力销安装间隙对推力测量结果的影响，根据安装节推力测量原理开展一系列推力校准试验，获
得了不同过载和安装间隙下的推力校准方程。通过结果分析得出飞行过载和安装间隙对推力测量结果的影响关系和解决措施。结
果表明：当飞行过载不超过2g 时，安装间隙为4～6 mm，且在发动机慢车以上状态时，可以忽略飞行过载和推力销安装间隙的影
响；当飞行过载超过2g 时，需要根据实际的过载系数和安装间隙对主安装节推力进行修正，以获得更高精度的推力测量结果。 |

| In order to study the influence of flight overload and thrust pin installation clearance on thrust measurement results,a series
of thrust calibration tests were carried out according to the principle of thrust measurement of mounts,and the thrust calibration equations
were obtained under different overload and installation clearance. The influence relation between flight overload and installation clearance
on thrust measurement result and the solutions were obtained by analyzing the results. The results show that when the flight overload is not
more than 2g,the installation clearance is 4~6 mm. The influence of flight overload and thrust pin installation clearance can be neglected
when the engine is above the idling rating. When the flight overload exceeds 2g,it is necessary to correct the mount thrust according to the
actual overload coefficient and the installation clearance,so as to obtain higher precision thrust measurement results. |
