一、BAe146—300型飞机襟翼系统的设计特点 BAe146—300型飞机是一种无前缘缝翼,固定式水平安定面,上单翼飞机。为保证起飞和着陆产生最大升力系数和飞机的可操纵性,襟翼的面积设计得很大,襟翼向下放出时,同时向后延伸,以增大机翼的有效面积。
China Northwest Airlines introduced BAe146—300 in the end of 1992. During the initial operation period, the flap lock—up occurred 36 times and endangered the flight safety. In order to cure this problem, our airlines set up 'the flap lock—up prevention group'. Through the analysis of flap design feature, were taken measures in operation and maintenance and obtained tangible results. Fault ratio was decreased from 2.8‰ to 0.147‰ at present. This article is an introduction of our airlines in solving the problem of flap lock—up.
