A Transonic Wind-tunnel Investigation of the Effects of Nacelle Shape and Position on the Aerodynamic Characteristics of Two 47 Degree Sweptback Wing-body Configurations

Report presenting an investigation in the 8-foot transonic tunnel to determine the effect of nacelle shape and position on the aerodynamic characteristics of two wing-body configurations at a range of Mach numbers. Some of the nacelles investigated included underslung and pylon-suspended nacelles located at the 40 percent-semispan station, submerged nacelles, and wing-tip nacelles. Results regarding the drag characteristics, mass-flow characteristics, schileren photographs, lift characteristics, and longitudinal stability characteristics are provided.
