摘要
不同气象环境下飞机部件的结冰外形是飞机结冰研究不可缺少的内容,它对开展结冰气动分析、结冰防护设计、结冰飞行操作和结冰适航取证等研究具有重要意义。结合国内外冰形测量技术发展现状,从接触测量方法和非接触测量方法两个方面分别介绍了现有冰形测量技术的操作流程及测量原理,系统分析总结了各自存在的优缺点。在此基础上,结合飞机结冰和结冰风洞试验的特点,归纳了冰形测量技术下一步发展面临的挑战,包括全类型结冰的精确测量、结冰全貌三维测量和结冰生长过程实时测量等,同时,从基础测量手段与数值计算融合发展的角度,展望了冰形测量方法未来的发展趋势。
Study on ice shapes under different icing conditions is an indispensable part in research on aircraft icing,and is important for aerodynamic analysis,anti-icing system design,flight operation and airworthiness certification after aircraft icing.This paper focuses on the measurement approaches for ice shape.With sufficient survey of corresponding works home and abroad,the technological process and principle of each contact and non-contact approach are introduced,and their advantages and disadvantages are also summarized systematically.Based on this summary and characteristics of in-flight icing and icing wind test,the challenges in the future are pointed out,which mainly include all type ice measuring,whole area measuring,and on-line measuring.Possible work on ice shape measurement in the future by combining basic approaches and numerical methods is also discussed.
