缩比模型演示验证飞行试验及关键技术.

Firstly, the flight tests and its application of scaled aircraft models at home and abroad are introduced in this paper. The study topics are summarized as follows： the demonstration and validation of aerodynamic configurations, the flight 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 control, quick model structure design and manufacture, model power system design and test, flight controller design and test, high precision measurement, and aerodynamic coefficients identification. Some results of CARDC (China Aerodynamics Research and Development Center) research on these key technologies are shown. Finally, the potential development directions of model flight test are prospected. [ABSTRACT FROM AUTHOR]
