| 摘 要： | 结合发动机加速模型,采用部件法编制了变几何通道时加速性能的计算程序,并详细分析了α1通道、α2通道调节延迟或超前时对其的影响.结果表明若几何通道超前调节,则推力和高压压气机稳定工作裕度增大,低压压气机稳定工作裕度减小,而延迟调节时变化趋势正好相反;其中α2通道调节产生的影响大于α1通道调节产生的影响.

| Abstract: | Based on the acceleration model,the acceleration code for engine with variable geometry channels was developed using component matching technique.The delay or ahead of schedule of high pressure compressor variable guide vanes and low pressure compressor variable guide vanes modulation was studied.The results show that for the case of the channel modulation ahead of schedule,there will be a increase of thrust and high pressure compressor surge margin,and a decrease of low pressure compressor surge margin,and vice versa for the case of modulation delay of schedule.The influence brings about by high pressure compressor variable guide vanes is higher than that of low pressure compressor variable guide vanes. |
