| 摘 要： | 为满足某型号液体火箭发动机定混合比随机无极变推力工作要求,研制了基于DSP处理器的随机推力调节控制驱动器。该控制驱动器实时接收随机变推力指令,在定混合比条件下,协调控制发动机系统上的燃料及氧化剂路调节阀,从而控制燃料及氧化剂流量,完成发动机的随机变推力控制。其参加多次发动机系统冷调试验及地面全程热试车,工作稳定可靠,实现了变推力双组元推进剂流量同步控制,精确控制发动机混合比,快速响应随机变推力控制要求。

| Abstract: | To meet the thrust control requirements of a liquid rocket engine,a random thrust adjustable controller based on DSP is developed.It receives random variable thrust instructions and varies the engine thrust accordingly by means of controlling the fuel and oxidant valves,while the mixture ratio is fixed.The controller showed good performances during cold-flow tests and full-duration hot firing tests.With the high stability and reliability,the controller achieved the synchronization control of variable thrust bipropellant flows in liquid rocket engine,in which the mixture ratio was precisely controlled,and swift response to random variable thrust control demand was realyzed. |

| Keywords: | random variable thrust fixed mixture ratio synchronization control adjustable valve |
