不可恢复失速是一种影响发动机操纵性的气动不稳定现象,70年代中期,F100发动机在刚投入使用时经常出现这种状况,并发生多次严重事故.为了解决这一问题,美国空军与GE和普惠公司从70年代起就开展专题研究,主要内容包括:发展和评定涡扇发动机不可恢复失速计算机模拟技术、建立减少或消除发动机与部件的不可恢复失速的设计准则、研究使发动机从失速中迅速恢复的最佳控制措施.产生不可恢复失速的原因发动机在工作中,压气机易产生
Non-recoverable stalls are a type of aerodynamic instability that affects engine maneuverability. In the mid-1970s, when the F100 engine was first put into operation, it frequently occurred and many serious accidents occurred. To solve this problem, the Air Force and GE And Pratt & Whitney to carry out thematic studies since the 1970s, the main contents include: the development and assessment of turbofan engine non-recoverable stalling computer simulation technology to establish or reduce the engine and components to reduce the design of non-recoverable stall criteria to study the engine stall from In the rapid recovery of the best control measures. Causes of non-recoverable stall engine at work, the compressor easy to produce
