民用飞机飞控系统副翼下垂浅析

在飞机起飞或着陆飞行阶段，当缝翼伸出襟翼放下时，副翼也随之对称地下偏一定偏度，这就增加了机翼的弯度，提高了机翼升力。从而减少了飞机起飞／着陆的速度和场长，改善了起飞和着陆性能。通过介绍X飞机与Y飞机的副翼下垂功能的历史发展、功能原理与功能实现，较详细地分析了副翼下垂功能的实现方式。

Aileron Droop Function Implemented by Civil Aircraft Flight Control System

When the flaps are lowered during takeoff or landing phase, ailerons on the both sides can be deflected simultaneously downward into the airstream to increase wing camber, supplementing flaps with lift augmentation. Takeoff or landing speeds and field length are reduced, thus performance is improved by using aileron droop. The research document introduces development process, basic principle and functional implementation on aileron droop function of X and Y civil aircraft in order to analyse aileron droop f...
