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 control logic of the ground spoiler protruding from the seven types of civil aircraft is compared and studied. The ground spoiler is on standby, fully and partially extended, the main wheel is grounded and the position of the thrust handle is analyzed and discussed. Finally, A320 as an example, two kinds of situations such as run-off and bouncing when landing are analyzed, and the influence of ground spoiler protruding automatic control logic on flight safety is analyzed. The analysis shows that the perfect ground spoiler extends out of the automatic control logic, which can improve the fault tolerance of flight operations and reduce the possibility of flight accidents caused by human factors.
