The frequency characteristics and statistical properties of the buffet loads measured on the unswept wing and tail of a fighter airplane have been studied in the stall and in the shock regime. The results indicate that the wing loads in buffeting can be treated as the Gaussian response of a simple elastic system. The tail loads appear to represent a more complicated pattern.

An investigation has been made to determine the effect of wing fences, a wing leading-edge extension, changing wing sweepback angle from 40 to 45 and 50 degrees, fuselage contouring, and varying horizontal tail height upon the buffeting response of some typical airplane configurations employing sweptback wings with high aspect ratios. The tests were conducted through an angle-of-attack range at Mach numbers varying from 0.60 to 0.92 at a Reynolds number of 2 million.
