    Abstract

    This paper deals with an experimental investigation of a family of cone-cylinder bodies having circular and equivalent elliptical (a/b = 2.0) cross sections with variation in nose and afterbody fineness ratios at Mach number 2.0. All elliptical bodies are tested at roll orientations of 0 deg (semimajor axis normal to cross flow velocity) and 90 deg (semiminor axis normal to crossflow velocity). The nose fineness ratios for these bodies are 1.0, 2.0, and 3.0, and the afterbody fineness ratios are 5.0 and 7.0. The effect of changing the cross section shape from circular to elliptical, the roll orientation, and the variation in nose and afterbody fineness ratios on aerodynamic characteristics are discussed.
