随着国内民用飞机迅速发展,民机安全性逐渐得到了人们的关注,结冰问题作为引起飞机飞行事故的主要原因之一,也慢慢受到了各专业设计师的高度重视。本文以某民用飞机为例,计算了该飞机低速构型下水滴收集系数及结冰情况,探索了飞机复杂构型结冰计算方法,并得出民用飞机在低速构型待机飞行时需考虑结冰对缝翼收放机构影响的结论。 With the rapid development of civil aircraft in China, the safety of civil aircraft has gradually drawn people’s attention. As one of the main causes of aircraft accidents, the problem of icing has been gradually taken seriously by professional designers. In this paper, taking a civil aircraft as an example, we calculate the collection coefficient and icing condition of the droplet under the low-speed configuration of the aircraft, and explore the calculation method of the complex configuration icing of the aircraft. We also conclude that the civil aircraft should consider the knot when the low-speed configuration standby flight Ice on the slat retract mechanism of the conclusion.
