随着飞机飞行速度的不断提高,着陆滑跑距离也跟着增长,单靠阻力极和起落架机轮的刹车,难以满足有效缩短滑跑距离的要求,而发动机的反推力装置就成为受重视的高效能减速装置。这种装置在发动机尾喷管上,可引导喷气流偏转向前。反推力装置的工作原理从60年代中到现在,反推力装置发展的型式很多,有蟀壳式的,格栅式的,花瓣式的和蝶式等。但它们的工作原理都相同,就是引导喷气流偏转向前。当反推力装置工作时,偏流活门打开,燃气向
As the flying speed of the aircraft continues to increase, the landing slip distance also grows. It is difficult to meet the requirement of effectively shortening the running distance with only the resistance pole and the brakes of the landing gear wheels, and the thrust reverser of the engine has become the focus of attention High-performance reduction gear. This device is located on the engine’s tailpipe and guides the jet to deflect forward. Anti-thrust device works From the mid-1960s to now, many types of development of thrust reverser, there are cricket shell, grille, petal and butterfly and so on. But all of them work the same way, which is to guide the jet to deflect forward. When the thrust reverser work, the bias valve opens, gas to
