- 摘要:
- 为了研究液体火箭发动机推力室喷注器多孔面板发汗冷却特性,以缩比推力室挤压热试验的形式开展了多孔面板发汗冷却特性研究,试验采用常温气氢对喷注器多孔面板进行发汗冷却。发汗冷却试验共进行5次,燃烧室压力为3.9~7.6 MPa,燃烧室氢氧混合比为2.8~7.2。研究结果表明在本试验研究状态下面板燃气侧温度为680~830 K,总结了推力室多孔面板渗透率与压降的工程关系式。
- Abstract:
- Hot fire tests were performed on subscale thrust chamber to investigate the transpiration cooling characteristics of thrust chamber injector porous face plate cooled by H2 of room tempe- rature. Five times tests were conducted under the conditions: combustion chamber pressure of 3.9-7.6 MPa, and O/F mixture ratio of 2.8-7.2. The investigation demonstrates that the hot gas wall temperature of the porous plate is 680-830 K under the test conditions. The engineering flow resistance function applied to thrust chamber porous face plate was obtained.
