摘要: 为保障大型飞机穿云飞行时的安全,大型客机需为机翼、风挡和短舱设计并安装防/除冰系统及结冰探测系 统。 首先,基于液态水含量(LWC,liquid water content)、环境温度和平均水滴直径(MVD,median volume diameter)3 个影响结冰强度参数,并结合 CS25 的附录 C 和附录 O,阐述了 4 种结冰包线的特点;其次,基于 当前防/除冰系统的设计水平,以 CS25.1420(a)(1)为审定目标梳理了防/除冰系统的适航条款;最后,基于 CS25 并参考 AC-25-28,针对飞机各系统特点开展了适航符合性方法分析,可为大型客机防/除冰系统的设 计和适航取证提供参考。

Abstract: To ensure the safety of large aircraft flying through clouds, large airliners should design and install wings, windshields and nacelle anti/deicing systems. First of all, based on the 3 parameters that affect icing intensity: liquid water content(LWC ), ambient temperature and median volume diameter(MVD), and in combination with appendixes C and O of CS25, this paper describes 4 kinds of icing envelops’ characteristics. Secondly, based on the current design level of anti/deicing system, the airworthiness terms of the anti/deicing system are reviewed with 25.1420(a)(1) asthe certification target. Finally, based on the CS25 and AC-25-28, airworthiness compliance analysis is carried out according to the characteristics of the aircraft's various systems, which provides a reference for the design and airworthiness certification of the large passenger aircraft anti/deicing system.

Key words: anti/deicing system, ice detection, airworthiness terms, means of compliance , CS25
