DOWNLOAD EBOOKAn investigation was conducted in the Langley 4- by 4-foot supersonic pressure tunnel at a Mach number of 2.2 to determine the aerodynamic characteristics of several ring-wing--body configurations. This investigation included tests for the bodies alone and for the ring-wing--body combinations; these tests were conducted through an angle-of-attack range from about -4 to 11 degrees. The data indicated that sizable reductions in body wave drag were obtained for the concaveafterbody configuration as a result of the favorable interference produced by the ring wing. However, a large percentage of the total drag was produced by the ring wing and struts, and thus the ring-wing configurations of these tests appear to offer no drag advantage over a conventional wing-body configuration. Of the three configurations tested, the half-ring wing in combination with a body having a parabolic afterbody had the lowest drag (0.35) and the highest maximum liftdrag ratio (4.9).

DOWNLOAD EBOOKAbstract: An experimental investigation has been performed to determine the effect of changes in body cross-section shape on the aerodynamic characteristics of bodies and wing-body combinations. A series of 13 bodies having a given length and given longitudinal distribution of cross-sectional area but various cross-section shapes were tested at a Mach number of 2.01. The bodies were tested alone and in combination with a 47° sweptback wing having a 6-percent-thick hexagonal section.
