THE SIMULATION AND FLIGHT VERIFICATION OF ACTIVE AEROELASTIC CONTROL

In this paper, an active aeroelastic control verification flight platform based on intelligent sensing is presented. The flight platform design concept is illustrated including key performance parameter, the aerodynamic layout and structure configuration. Detailed simulations in aerodynamics, structural dynamics and active aeroelastic control are conducted to ensure the safety and effective verification of the flight platform. Finally, a basic fight test for gust alleviation by active aeroelastic control is executed. The flight test result demonstrate that the wing tip vibration response is reduced by more than 30% via active aeroelastic control system, and the load envelope is increased by 12%. At the same time, the reliability and technical maturity of the active aeroelastic control system are verified, which lays the technical foundation for the further improvement of the test speed and the active control effect.
