Aerodynamic Characteristics of a 45 Degree Sweptback Wing-fuselage Combination and the Fuselage Alone Obtained in the Langley 8-foot Transonic Tunnel

Robert S. Osborne, Mugler John P

Abstract

Report presenting a fuselage and wing-fuselage combination with a wing of 45 degrees sweepback of the 0.25-chord line, aspect ratio 4, taper ratio 0.6, and NACA 65A006 airfoil sections in the slotted test section of a transonic tunnel for a range of Mach numbers and angles of attack. Results regarding lift characteristics, drag characteristics, lift-drag ratios, pitching-moment characteristics, a comparison with other test results, and base-pressure characteristics are provided.
