- 摘要:
- 液体火箭发动机试验中，流量和转速传感器输出的信号为不规则的频率信号， 对不规则频率信号的调理是准确测量的关键环节。介绍了液氧煤油发动机地面试验中流量和 转速参数信号的调理技术，重点阐述频率信号调理器的原理、功能、设计要点及调试方法， 给出了频率信号调理器的关键环节原理图。使用这种频率信号调理器对液氧煤油发动机试验 中流量和转速传感器输出的频率信号直接进行调理，保证了频率型参数的准确测量。
- Abstract:
- In a liquid rocket engine test，the signals transmitted by flow and rotating speed sen· sors are irregular frequency signals．Therefore，modulations of these signals are the key links for ac— curate measurement．In this paper the signal modulating technique of flow and rotating speed parameters was introduced，the principals，function and the key points of design and test methods were emphatically illustratied．The principal figure of the key link of frequency signal modulators was presented．The described frequency signal modulators directly modulate the frequency signals transmitted by the flow and rotating speed sensors during LOX／kerosene rocket engine tests．The accurate measurement of frequency parameters can be reached by applying the modulators．
