Abstract

Oscillating aerodynamic loads induced by transonic buffet may cause structural fatigue and flight accidents, making transonic buffet control a hot topic in aeronautical engineering. In this paper, two active control strategies (open-loop and closed-loop) are proposed to decrease or suppress the transonic buffet by trailing edge flap based on Unsteady Reynolds-averaged Navier-Stokes equations and Spalart-Allmaras turbulence model. The buffet loads can be reduced by 60% with the open-loop strategy, and the buffet in a wider range of Mach numbers can be suppressed completely with the closed-loop strategy.
