民机地面扰流板伸出自动控制逻辑研究及对飞行安全影响分析

Research of Auto-extension Logic of Ground Spoiler in Civil Aircraft and Analysis of the Influence on Flight Safety

对7种型号民机的地面扰流板伸出自动控制逻辑进行了对比研究,对地面扰流板待命、完全与部分伸出、主轮接地、推力手柄位置等方面进行了分析讨论;最后以A320为例,就着陆时冲出跑道和发生弹跳两种情况,分析了地面扰流板伸出自动控制逻辑对飞行安全的影响。分析表明,完善的地面扰流板伸出自动控制逻辑,可以提升对飞行操作的容错性,降低因人为因素导致飞行事故的可能性。

The ground spoiler auto-extension logic of 7 types of civil aircraft are researched in this article, including the influences of ground spoiler armed, full/partial extension, main landing gear seen on ground and thrust levers position. At last, the influence on flight safety by auto-extension logic of ground spoiler is studied based on the example of A320 runway excursions and bounces at landing. It is concluded that the modified auto-extension logic of ground spoiler can increase the flight operation tolerance and decrease the probability of flight accidents caused by human factor.
