A method and design system for a low drag vehicle includes determining a plurality of configurations for at least two different Mach numbers that minimize the rate of change of cross-sectional area of the vehicle in accordance with the Sears-Haack minimum drag body. A user can specify design objectives and constraints to meet in determining optimum configurations for the vehicle, and the configurations are averaged to determine a final configuration. The at least two configurations can be weighted to emphasize optimum performance at particular operating ...
1. A method for designating a low drag vehicle comprising:determining at least two vehicle configurations that minimize the second derivatives along cross-sectional area distributions of the vehicle configurations, wherein at least one of the vehicle configurations is determined at a Mach number and a roll angle that is different than the other of the at least two vehicle configurations;determining second derivative curves of the cross-sectional area distributions of the vehicle configurations;applying weighting factors to the second derivative curves to...
