摘　　要：高空模拟试验是民用航空发动机适航取证的符合性验证手段之一。基于中国民航规章CCAR-33部33.68条款“进气系统结冰”的要求,对进气系统结冰高空模拟试验验证开展研究,以表明符合性。本文提出了进气系统的结冰试验点的选取方法、分析了试验的流程、明确了试验结果评估方法,并针对试验设备提出了高空舱、测试装置和试验设备配备要求,介绍了典型符合性验证案例。本研究可为国内民用航空发动机开展进气系统结冰适航符合性验证工作提供技术支持。High-altitude simulation test is one of the conformity verification methods for civil aero-engine airworthiness certification. Based on the requirements of Clause 33.68 of CCAR33, Civil Aviation Regulations of China, "Air intake system icing", the high-altitude simulation test verification of air intake system icing is studied to show the compliance.The selection method of icing test point of air intake system is put forward, the test flow is analyzed, and the evaluation method of test results is defined. The requirements of high empty warehouse, test device and test equipment are put forward for test equipment, and typical compliance verification cases are introduced. This study can provide technical support for domestic civil aero-engines to verify the airworthiness of air intake system icing.
