AbstractSoftware for aerospace vehicle surfaces is applied and further developed as a Parameterized Geometry Preprocessor suitable for aerodynamic design and optimization. Airfoil families are designed with knowledge based parameters and their variations are used for optimization strategies, as well as with spanwise parameter variations to shape arbitrary lifting wings. Integration with fuselage results in a one-block surface grid for wing-body configurations which is found practical for rapid prototype design. Generation of scalar distributions along surface gives target pressure functions to support the input of inverse design codes. Case studies derived from the NEXST (National EXperimental Supersonic Transport) supersonic transport project and other concepts illustrate the value of this approach.
