设计了脉冲爆震发动机电磁阀式供油系统,采用氮气挤压供油方法,研究了燃油压力及其响应时间随氮气压力与电磁阀输入电流的变化规律,同时对低频与中高频脉冲爆震试验中油压响应时间与频率进行对比分析。研究发现,提高蓄能器中氮气压力可显著加快油压响应;电磁阀输入电流越大,燃油压力响应越快;工作频率越高,燃油达到预定压力所需时间越长。研究结果对脉冲爆震发动机供油系统的设计与优化具有一定的参考价值。
The design of a pulse detonation engine solenoid valve oil supply system, the use of nitrogen extrusion fuel supply method, the study of the fuel pressure and response time with the nitrogen pressure and solenoid valve input current changes, while low and medium-frequency pulse detonation The hydraulic response time and frequency in the experiment were compared. The study found that increasing the nitrogen pressure in the accumulator can significantly speed up the hydraulic response; the greater the input current of the solenoid valve, the faster the fuel pressure response; the higher the operating frequency, the longer the time required for the fuel to reach the predetermined pressure. The research results have certain reference value for the design and optimization of the pulse detonation engine oil supply system.
