民机飞行结冰参数的模拟与校准

The Simulation and Calibration of Icing Parameters for Civil Aircraft

摘要:

结冰问题的研究对于民用飞机设计十分重要,采用结冰风洞试验是主要的方法之一,欧美国家有很多成熟的结冰风洞用于型号研究。结冰风洞中需要对很多参数进行控制,其中水雾参数精确控制的难度很大,而且一般通过间接方法来进行测试校准,往往误差较大,导致不同结冰风洞试验结果往往有所差异。文章介绍了在意大利宇航中心的IWT 结冰风洞完成的冰风洞校准试验,对结冰风洞水雾参数校准方法进行了阐述,为民机结冰风洞研究提供参考。

Abstract:

It is important for civil aircraft design to research the icing influence. One of the main ways is adopting the icing wind tunnel test, which are extensively used for airplane research in USA and Europe. Many parameters were controlled during the icing wind tunnel,which cloud parameter was controlled with large difficulty and was measured indirectly, so the error was considerable which led to large difference from icing wind tunnel to another.Icing wind tunnel parameter calibration test in CIRA-IWT was introduced, and the cloud parameter correction methods were illuminated, which can provide reference to the icing wind tunnel research for civil aircraft.
