介绍了某型支线客机机翼防冰系统的性能验证思路,即通过采用2.5D试验模型验证三维防冰系统的性能。选取一个典型状态点分别进行了2.5D及三维模型的性能计算分析,同时进行了相同状态点时2.5D模型的冰风洞试验结果分析,最后将2.5D模型计算结果与试验结果进行对比分析,修正3D模型的计算结果,从而达到验证整个防冰系统性能的目的。

A certain type of civil aircraft wing anti-ice system performance validation was introduced briefly first:the 2. 5D test model to verify the performance of three dimensional wing anti-ice system. A typical test condition selected to carry out the calculation of 2. 5D model and 3D model performance, meantime the icing wind tunnel test result of 2. 5D model for same condition was analyzed. At last, the 2. 5D model calculation results with the experi-mental results were compared and analyzed, and fixed the calculation results of 3D model,so as to achieve the pur-pose to verify the ice protection system performance.
