| Abstract | For modern aircraft with higher sweep angles flying at higher incidence, unsteady and burst vortex flow in the vicinity of the wing and downstream lifting surface lead to strong unsteady airloads and buffeting'. Thus, investigations were conducted in the Institute for Aerospace Research (lAR) Low Speed Wind Tunnel (LSWT)2 to study the buffet characteristics of the Standard Dynamics Model (SDM)3, a generic fighter aircraft configuration. Since the spectrum of the aerodynamic input load is reasonably flat over the frequency range of interest, the solution to the equation of the motion is easily solved in the frequency domain for a given aerodynamic loads and vice versa. Following Jones4 and Mabey3, it is suggested that 4mG(n) is the best parameter to use as a measure of buffet excitation due to flow separations and unsteadiness and to denote this as the buffet excitation parameter. |
