摘　　要：利用冬季自然低温进行结冰试验是飞机大尺寸部件和整机结冰试验的有效方法。文章总结了法国、加拿大、美国、俄罗斯等国家季节性结冰风洞的主要参数,分析了季节性结冰风洞在大尺寸机翼、螺旋桨和飞机等方面的试验能力。基于中国航空工业空气动力研究院季节性可移动式结冰风洞开展了螺旋桨结冰和机上地面结冰试验方法研究,分析了螺旋桨结冰和冰脱落规律,对于进一步研究螺旋桨结冰问题、发展机上地面结冰试验技术具有参考价值。提出了一种季节性、可移动、模块化组装的直流式结冰风洞概念设计方案,利用我国冬季低温自然环境,每年11月至次年3月具备结冰试验条件,试验窗口期与国外同类设施相当,可满足大尺寸模型和飞机结冰试验需求,为我国建设大型季节性结冰风洞、发展结冰风洞试验技术提供参考。An open circuit natural icing wind tunnel sucking cold air from the outside in winter provides affordable icing wind tunnel test methods for full scale models and aircrafts. Information of natural icing wind tunnels is summarized, and test capabilities on large scale wings, propellers,and aircrafts are analyzed. The propeller and aircraft icing test methods were researched in Harbin using a single module natural icing wind tunnel, and ice accretion and shedding on the propeller are documented and analyzed, test results of which have a certain reference value for propeller and aircraft icing researches. A seasonal, moveable and assembled icing wind tunnel concept is presented which can take the advantage of cold winter climate, and allows a similar period from November to March to conduct icing tests compared with the outdoor icing test facility in Winnipeg, Canada. Researches provide references for the construction of national large scale natural icing test facilities and development of test methods.
