摘　　要：首先介绍了国内外缩比模型验证机飞行试验及其应用情况,总结了模型飞行试验的四大研究领域:气动布局演示验证、气动力飞行试验、危险边界飞行试验、新概念新技术演示验证试验;其次,分析了模型飞行试验在带动力自主飞行、模型快速结构设计与制造、模型动力系统设计与测试、飞行控制设计与测试、高精度测量与气动参数辨识等关键技术领域的发展趋势,并给出了中国空气动力研究与发展中心在这些技术方面的部分研究结果;最后,对模型飞行试验的未来发展方向进行了展望。Fi rstly, the f l ight tests and its application of scaled aircratt models at home and abroad are introduced in this paper. The study topics are summarized as fo l low s： the demonstration and validation of aerodynamic configurat ions, the f l ight test of aerodynamic forces,the flight test of dangerous boundaries, as well as the demonstration and validation test with new concepts and technologies. Secondly,this paper analyzes the key technologies of model flight test such as powered flight with autonomous c o n tro l, quick model structure design and manufacture, model power system design and test, flight controller design and test, high precision measurement, and aerodynamic coefficients ident if ication. Some results of CARDC （China Aerodynamics Research and Development Center） research on these key technologies are shown. Final ly,the potential development directions of model flight test are prospected.
