Effect of thrust reverser on the deceleration performance of civil aircraft

  • 摘要:

    为评估反推力装置提供的反向推力与其结构件质量增加对民航飞机减速性能的综合影响,借助克兰菲尔德大学发动机总体性能仿真软件Turbomatch,参考CFM56发动机建立正、反推力状态发动机模型,并以A320飞机为配装对象开展研究。将风扇及涡轮直径做为特征参数,完成推进系统质量的初步估算。对比飞机在干燥跑道及雨雪条件下常规着陆过程中滑跑距离及减速时间,完成反推排气角度、跑道条件等影响因素对反推力装置提升飞机减速性能收益分析。研究表明:配装反推力装置轴向排气角度越小,飞机减速性能更加。以55°排气角度为基础,减小10°的排气角度可带来约7%的减速收益。反推力装置在湿滑跑道的减速收益更大,比干燥跑道滑跑距离缩短约41%,滑跑时间缩短32%。
