摘要
液体火箭发动机用过滤器是保持工质清洁,保证试验设备和发动机可靠工作的重要设备,合理的过滤器设计是保证液体火箭发动机发射成败与否的关键因素。因此,为了防止液体火箭发动机液路、气路等管路出现多余物影响发动机正常工作,根据发动机系统的要求设计了某过滤器,从理论上研究了其流阻特性,并开展了液流试验研究。通过对比分析,理论和试验结果表明,所设计的过滤器满足发动机系统的要求。
Liquid rocket engine filter is an important element which ensures clean working liquid and reliable operation of the test equipment and engine.The reasonable filer design is a key factor to ensure liquid rocket engine success.Therefore,in order to prevent extra material appearance in liquid pipeline,gas pipeline etc.which would affect engine＇s normal work,a filter was designed according to the requirements of the engine system.The characteristics of the pressure drop are studied theoretically.And the liquid flow experiment is carried out.The analysis of theory and experimental results shows that the designed filter meets the requirements of the engine system.
