摘要
Д—30КУ—154Ⅱ发动机是内外函双转子涡轮喷气发动机,n_(2起飞)不足是该型发动机在气温较高季节常见的故障现象之一。作者根据发动机燃油泵调节器的构造特点和本单位的使用维护经验以及统计资料,对产生的故障现象进行了分析,认为引起故障的原因,一是与发动机的长期使用有关。二是与调整方法有关。最后,作者介绍了排除发动机 n_(2起飞)不足现象的方法并提出了应当注意的事项。
The154 engine is out/inter flow doal--roter turbine-jet engine, n_2 (take of) isn't sufficient is the subject engine's main failure in high temperature seasons. According the engine fuel pump's structure and mantenance experence, the author studied statistic of failures, found the reason of failure caused is:a, long useage time;b,ad just method during mantanence, last, author introdused a method to solve n_2 (t. o) low and gived some cautions.
