An experimental investigation has been made at a Mach number of 10.03 to determine the longitudinal aerodynamic characteristics of a series of power-law bodies having values of the exponent of 0.25, 0.50, 0.66, 0.75, and 1.00, and a theoretical hypersonic minimum-wave-drag body. The bodies had the same length and volume, and the theoretical body shape was determined under the geometric constraints of prescribed length and volume. For each body, cross-sectional shape was altered from circular to elliptic, while maintaining a constant longitudinal distribution of cross-sectional area. Results of the investigation may be summarized in the following observations. For the series of power-law bodies tested, a minimum in the variation of zero-lift drag with body exponent occurs for an exponent of 0.66 for ellipse ratios of 1.0 or 2.0; a resultant maximum in the variation of maximum lift-drag ratio with body exponent was also found for an exponent of 0.66 for ellipse ratios of either 1.0 or 2.0. The zero-lift drag characteristics of the theoretical minimum-wave-drag body are slightly lower than those noted for the 0.66-power body, and the resultant maximum lift-drag-ratio characteristics are somewhat higher for ellipse ratios of either 1.0 or 2.0. The effects of increasing ellipticity, for a given power body or the theoretical body, resulted in an almost constant incremental increase in maximum lift-drag ratio, independent of body longitudinal contour; these increases were primarily a result of the improved lift characteristics.
