模型飞行试验(又称“模型自由飞”)是空气动力学研究三大手段之一,在飞行器研制及空气动力学科发展中有着不可替代的作用。著名科学家钱学森在规划我国空气动力技术能力和研究途径时多次强调其重要性,曾指出,“我们发展自己的飞机,要发展模型自由飞这种办法,解决风洞吹风不易解决的气动问题”。经过多年建设发展,我国风洞试 Model flight test (also called “model free flight”) is one of the three major means of aerodynamics research and plays an irreplaceable role in the development of aircraft and the development of aerodynamics. Qian Xuesen, a famous scientist, has repeatedly emphasized its importance in planning China’s aerodynamic capabilities and research approaches. He pointed out: “We have developed our own aircraft to develop a model that is free to fly and solve the aerodynamic problems that are not easily solved by the wind tunnel blowing ”. After years of construction and development, wind tunnel test in China
