)ENTIAL NATIONAL ADVISORY COMMITTEE FOR AERONAUTICSRESEARCH MEMORANDUM ADDITIONAL EXPERIMENTS WITH FLAT-TOP WING-BODYCOMBINATIONS AT HIGH SUPERSONIC SPEEDS By Clarence A. Syvertson, Thomas J. Wong,and Hermilo R. Gloria SUMMARY An experimental study is made of the effects of several variations in configuration geometry on the aerodynamic characteristics of flat-top wing-body combinations. In general, these configurations consist of one half of a body of revolution mounted beneath a wing of essentially arrow plan form. At the root, the wing leading edge coincides with the nose of the fuselage and the trailing edge coincides with the fuselage base. Variations in model geometry studied include wing trailing-edge sweep, the addition of auxiliary bodies, downward deflection of wing tips to simulate vertical fins, wing dihedral, wing leading-edge sweep, fuselage fineness ratio, and fuselage profile shape. Lift, drag, and pitching-moment characteristics were obtained at Mach numbers from 3.00 to
