机翼结霜和薄冰的危险性分析

近年来随着飞机的使用越来越广泛,机翼积冰现象已经成为飞机起飞及运行阶段需要着重解决的问题,虽然霜和薄冰也属于积冰,但机翼结霜和薄冰往往容易被人们忽略.首先列举了机翼积冰所导致的飞行事故的案例,总结了机翼积冰现象的研究背景、国内外研究现状,讨论了积冰的影响因素,分析了积冰对飞行的影响,根据CCAR-25部对起飞速度的适航规定,利用公式推导,运用风洞实验数据从理论上分析了CRJ-200机翼积冰是如何导致飞机失速的.针对机翼结霜和薄冰的现象,列举了一些防/除冰方法,并对飞机在不同状态下积冰时应采取的措施提了几点建议.

Risk Analysis of Frost and Ice on Wing

In recent years ,with more and more extensive use of aircraft ,wing icing has became a problem that during the plane′s take-off and running should be solved .Although Frost and ice are also the types of icing , but the wing frost and thin ice are often easy to be ignored .First enumerated the cases of flight accidents caused by wingicing and summarized the wings icing research background and the current situation at home and abroad.Discussed the influence factor of icing ,mainly analyzed the effects of icingon the aircraft .Accord-ing to the CCAR-25 Department of the departure speed of airworthiness requirements ,using the formula ,based on the wind tunnel test data ,theoretical analysis of the CRJ-200 wing icing was how to cause the aircraft to stall.For the phenomenon of wing icing ,cites a number of anti/de-icing methods on aircraft icing in a differ-ent state.
