A Transonic Wind-tunnel Investigation of the Effects of Body Indentation, as Specified by the Transonic Drag-rise Rule, on the Aerodynamic Characteristics and Flow Phenomena of an Unswept-wing-body Combination

Claude V. Williams

Abstract

Report presenting comparisons of the aerodynamic characteristics and flow phenomena at transonic speeds for two unswept zero-taper-ratio wing-body combinations. The first had a cylindrical afterbody, while the second had an indented afterbody in the region of the wing-body juncture. Results regarding force characteristics, flow surveys, and an interpretation of the results are provided.
