Investigation of the Low-speed Aerodynamic Characteristics of a Variable-sweep Airplane Model with a Twisted and Cambered Wing

Robert E Becht, Albert G Few, W. B. Kemp

Abstract

Report presenting an investigation to determine the low-speed characteristics of a variable-sweep airplane model with a twisted and cambered wing. The wing was designed to have a uniform load distribution at a Mach number 1.10 and a lift coefficient of 0.25 and 50 degrees sweep. Results regarding lift characteristics, drag characteristics, lift-drag ratio, pitching-moment characteristics, dynamic pressure and downwash at the tail, effect of flaps, and lateral stability characteristics are provided.
