近期,拥有B737飞机的各航空公司纷纷向各协议航站发出《技术通告》,要求检查B737飞机偏航阻尼器,确认无异常,才允许放行,这是因为B737近期在空中出现“飘摆”所致。现代大型高速运输机大都采用了后掠翼,后掠角增大容易使飞机产生出一些新的飞行品质,其中之一便是“飘摆”。飞行中发生飘摆的危害不可低估,它会使飞机迅速降低高度,并诱发飞行员错误地多带杆,容易导致飞机失速。而一旦发生失速,飘摆又会极大地干扰飞行员对失速的改出,甚至会造成飞机结构的损坏及发生更严重的事故,鉴于上述情况,本文就下面几个问题进行一些
Recently, airlines with B737 aircrafts issued “technical circulars” to each of the participating airlines to require inspection of the Y-damper of the B737 to confirm that there was no abnormality before allowing the release. This is because B737 recently appeared in the air “Due. Most of the modern large-scale high-speed transport aircraft using swept-wing, swept angle increases easy to make the aircraft to produce some new flight quality, one of which is ”floating". The dangers of flying in flight should not be underestimated, it will quickly reduce the height of the aircraft, and induce the pilot to mistake the pole with more easily lead to the aircraft stalled. In the event of a stall, the drift will greatly interfere with the pilot’s replacement of the stall, and even cause damage to the aircraft structure and more serious accidents. In view of the above, this article will discuss the following issues
