涡喷七发动机全加力状态温度高推力小问题,是长期没有解决的生产关键。文章从实际出发,进行理论计算和统计分析,从而找到产生故障的原因,其中有大气湿度的影响,发动机涡轮部件性能退化,~t4温度受大气温度的影响和~t4温度场的不均匀性。针对以上原因,提出了行之有效的排故措施,对解决我国当前使用的双转子发动机经常出现的温度高推力小问题有广泛的现实意义。
Whirlpool seven engine full afterburner temperature high thrust small problem, is the long-term production key to solve. Based on the actual situation, the article carries out theoretical calculation and statistical analysis to find out the cause of failure. Among them, the influence of atmospheric humidity, the degradation of engine turbine components, the influence of atmospheric temperature on ~ t4, and the nonuniformity of ~ t4 temperature field. For these reasons, put forward an effective troubleshooting measures to solve the current dual-rotor engine used in China often have a small problem of high temperature thrust has a wide range of practical significance.
