摘　　要：在结冰风洞建立热气供气防除冰试验系统是开展热气防除冰试验的主要手段,为满足我国一系列国产飞机防除冰系统设计与结冰适航审定需求,中国空气动力研究与发展中心依托3 m×2 m大型结冰风洞开展了热气供气防除冰试验技术研究,自主研制了热气供气防除冰试验系统。设计并研制了数字阀流量控制单元、电加热器单元、流量控制单元等试验子系统,建立了试验流程与方法,构建了完善的多路热气供气防除冰试验技术,并对某小型航空发动机进气道部件开展了双路防除冰试验验证,试验结果表明:热气供气防除冰试验系统可模拟真实压气机引出的热气,具备多路热气供气试验能力,温度控制精度可达±1℃,流量控制精度可达±1%,性能指标优异,为下一步我国飞行器防除冰试验系统设计与适航审定提供了有力支撑。The establishment of hot air supply anti/de-icing test system in icing wind tunnel is the main means to carry out hot air anti/de-icing test. In order to meet the requirements of anti/de-icing system design and icing airworthiness certification for a series of domestic aircrafts, China Aerodynamics Research and Development Center (CARDC) carried out research on the hot air supply anti/de-icing test technology based on the 3 m×2 m large-scale icing wind tunnel, and independently developed the hot air supply anti/de-icing system. The digital valve flow control unit, electric heater unit, flow control unit and other test systems were designed and developed, and the test process and method were established. The perfect multi-channel hot sir supply anti/de-icing test technology was constructed, moreover, the dual-channel hot sir supply anti/de-icing test of a small aero-engine inlet was carried out. The test results indicated that the hot air supply anti/de-icing test system can simulate the hot air from the real compressor, allowing for multi-channel hot air supply test. The temperature control accuracy can reach ±1 ℃ and the flow control accuracy can reach ±1%. Meanwhile, it can provide a strong support for the anti/de-icing test system design and airworthiness certification of aircraft in China.
