摘要/Abstract

摘要： 为推动过冷大水滴(SLD)结冰适航验证工作的开展，首先从SLD 异常结冰微观机理、结冰后飞行性能评估方法和SLD 结冰安全防护技术3 方面，系统综述了国内外对SLD 结冰问题的研究进展；其次结合常规结冰条件下的民机结冰适航验证思路，对SLD 结冰的适航验证方法进行了探索；最后，针对未来SLD 结冰研究和适航验证工作面临的挑战，提出理论研究与工程实践相结合、加强临界条件验证能力建设、推动SLD结冰适航标准和程序修订的建议，以此突破SLD 结冰研究和适航验证面临的瓶颈，解决民机研制和取证中的关键问题。

Abstract: In order to implement the research of supercooled large droplet(SLD) icing airworthiness verification, the SLD icing research progresses in and abroad have been systematically summarized from the following three aspects: the microscopic mechanism of SLD anomaly icing, the evaluation method of flight performance after icing, and the safety protection technique of SLD icing. Then, basing on the common thoughts of civil aircraft icing airworthiness certification under conventional icing conditions, the airworthiness certification approaches of SLD icing are explored. Finally, looking ahead to the future challenges for SLD icing research and certification approaches, promoting suggestions are proposed including the combination of theoretical research and engineering practice, enhancement of verification capacity under critical condition and building of SLD icing airworthiness standards and procedure, helping break bottlenecks and solve the key problems of civil aircraft development.

Key words: supercooled large droplet, icing mechanism, icing aerodynamics, civil aircraft airworthiness certification
