Abstract

The design of aerodynamic configuration and control system for high maneuverability fighter aircraft has encountered severe problems regarding to flow/motion/control coupling. Furthermore, application of radical technologies makes it face higher technical risks during the development process. Wind tunnel model flight test is a significant approach to studying the aerodynamics/dynamics/control characteristic of aircraft and to reducing the technical risks. The principle of low speed wind tunnel model flight test technology and its state-of-the-arts are introduced. The main characteristics of the test and its role in supporting the development of advanced fighter aircraft, application stage, and main challenges are analyzed, providing guidelines for the development and application of the test technique. The development and application of low-speed wind tunnel model flight test technology is a promising way to understand and optimize the aerodynamic characteristics and control performance of fight aircraft. It has become an important supporting technology for developing new generation fighters, reducing risks for flight test of full-scale aircraft, and accelerating the process of new technologies applying to industry.
