摘要:

结冰将严重影响直升机飞行性能,威胁直升机飞行安全,旋翼是直升机受到结冰影响的主要部件,如何低能耗、高效率地开展旋翼防除冰是当前直升机亟待解决的问题。旋翼结冰与固定翼不同,其流场更加复杂,许多在固定翼飞机上表现良好的防除冰技术无法在直升机旋翼上直接使用。首先介绍了旋翼结冰的特点及其主要响应因素,概括了结冰对直升机气动性能的影响;其次重点阐述了现有防除冰技术的原理、优劣和适用范围;详细论述了以电热-机械式和电热-涂层式为代表的复合防除冰技术的优势,提出了直升机旋翼防除冰后续发展的建议,对于促进直升机旋翼防除冰技术的发展具有一定的指导意义。

Abstract:

Icing will seriously affect the flight performance of helicopters and threaten their flight safety. The rotor is the main component of helicopters affected by icing, and how to carry out rotor anti-icing and de-icing with low energy consumption and high efficiency is an urgent problem for helicopters. Unlike that of fixed wings, rotor icing has a more complex flow field, and many anti-icing and de-icing technologies that perform well on fixed wing aircraft cannot be directly used on helicopter rotors. The characteristics and main response factors of rotor icing are introduced firstly, and the impact of icing on the aerodynamic performance of helicopters is summarized. Then, the principles, advantages and disadvantages, and scope of application of existing anti-icing and de-icing technologies are emphasized. The advantages of composite anti-icing and de-icing technologies represented by electrothermal-mechanical and electrothermal coating technologies are discussed in detail. Suggestions for the subsequent development of helicopter rotor anti-icing and de-icing are proposed. This article has certain significance for promoting the development of helicopter rotor anti-icing and de-icing technologies.

Key words: helicopter, rotor icing, electric anti-icing and de-icing, mechanical deicing, hybrid anti-icing and de-icing
