A Flight Investigation of the Effects of Compressibility on Applied Gust Loads

Abstract

Two Jet-propelled airplanes were flown at different speeds in rough air to investigate the effects of compressibility on applied gust loads. Data were obtained over a Mach number range of O.25 to 0.68 for effective gust velocities up to l5 feet per second. An analysis of the results indicated that no compressibility correction to the slope of the lift curve was necessary up to a Mach number of 0.68 for gust velocities up to 9 feet per second. Data obtained for gust velocities greater than about 9 feet per second were insufficient for analysis.
