本文对姿态控制发动机在液体火箭发动机试车台上(LRTS 图1),试验的结果进行了分析,并研究了发动机的推力—时间(F—t)曲线被各种频率的谐波所干扰的现象。在分析各种谐波成因的基础上,为减弱以致消除这些干扰因素,提出了适用于姿态控制发动机用的热试车台的新方案。
In this paper, the results of the test of the attitude control engine on the liquid rocket engine test bed (LRTS Figure 1) are analyzed and the phenomenon that the thrust-time (F-t) curve of the engine is disturbed by the harmonics of various frequencies . On the basis of analyzing the causes of various harmonics, in order to reduce these interference factors, a new scheme of hot test bench for attitude control engine is proposed.
