| 1. | The results indicate that with the coefficient of residual oxygen being less than 1 or around 1 , when the fuel is injected into the combustor at the same combustor pressure , the higher the combustor temperature is , the less the coefficient of residual oxygen is when auto - ignition occurs ; when the fuel is injected into the combustor at the same combustor temperature , the larger the combustor pressure is , the less the coefficient of residual oxygen is when auto - ignition occurs ; when the fuel is injected into the combustor at the same combustor temperature and pressure , the bigger the coefficient of residual oxygen is , the more easily auto - ignition occurs
研究结果表明,当推进剂处于余氧系数小于1或略大于1时,在燃烧室压力相同的情况下喷入燃料,燃烧室温度越高,可自燃的余氧系数越小;在燃烧室温度大致相同的情况下喷入燃料,燃烧室压力越高,可自燃的余氧系数越小;在燃烧室温度、压力大致相同的情况下喷入燃料,余氧系数越高,自燃发生的可能性越大。 |
