High-Speed Wind-Tunnel Tests of a 1/14-Scale Model of a Four-Engine Cargo Airplane

Abstract

High speed characteristics of a cargo airplane, particularly the longitudinal stability and control in dives, were investigated in a 16-ft high-speed wind tunnel. Results of tests indicated that no important changes in longitudinal stability or controllability occurred until the speed exceeded the predicted maximum level flight speed by more than 38%. Above this speed, large changes occurred in the stability and lift coefficient for balance.
