| 摘 要： | 为了满足现代飞机高性能的要求,应尽可能提高发动机的最大推力,从而使压气机喘振裕度下降。当发动机遇到恶劣的工作条件时,如飞机机动飞行引起进气道畸变,加力燃烧室点火,发动机吸进发射火炮或导弹产生的废气等,可能引起发动机气动力不稳定,即喘振或失速。喘振时,压气机出口总压和流量出现大幅度振荡,涡轮前总温急剧上升,发

| Abstract: | A dynamic model of two-spool turbo-jet engine with, post-stall capability is developed in this paper. In compressor model unun-stalled stalled and in-in-stalled stalled characteristics are included. Both combustors with rich fuel and lean fuel are considered. By use of conser vation equations of fluid energy, mass and momentum, the volume dynamics are described in detail. The utilization of this model with surge or stall is successfully induced by change of nozzle area, main combustor fuel-step and closing nozzle. The simulation results to induce surge coincide with the test results at home and abroad. |
