摘　　要：ARJ21-700飞机机翼防冰系统的合格审定试飞需要严格按照CCAR25部R3版的要求进行。为了保证适航试飞的科学性,围绕防冰系统的适航条款,详细介绍了试飞方案的设计过程,并采用CFD计算方法对试验过程进行了数值模拟研究,获得了一套完整的试验方法,并应用到飞行试验过程中。结合飞行试验结果,对CFD的计算方法进行了验证,结果表明,该试验方法能够很好地为实际的飞行试验提供技术参考和指导,取得了良好效果。The wing anti-ice（WAI） system type certification flight test of ARJ21-700 aircraft should be conducted strictly according to CCAR25 （ R3 ）. In order to ensure the scientific nature of flight test, this paper detailed the design process of the flight test plan based on airworthiness provisions, and CFD calculation method is used to perform numerical simulation of the flight test process. A complete set of flight test methods are obtained and used in flight test. By combining the flight test results, the CFD calculation method is verified, and the results show that the approach can well provide technical reference and guidance for actual flight test.
