Preliminary Development of an Approximation Procedure for Supercritical Wing Design Optimization Applications.
Abstract
An investigation was carried out involving the preliminary development of an approximation procedure and associated computational codes for rapidly determining approximations to nonlinear, three-dimensional flow solutions, with the purpose of establishing a method for minimizing the computational work requirements associated with design optimization studies of supercritical wings. The results here concern the extension of a previously-developed successful approximation method for determining accurate approximations to two-dimensional nonlinear transonic flows involving the simultaneous change of multiple geometric and/or aerodynamic parameters. The specific development involves combination of the nonlinear approximation procedure with the FLO22 three-dimensional wing transonic flow solver together with the CONMIN optimization program in a configuration suitable for supercritical wing design/optimization studies. Keywords include: Coordinate straining, Supercritical flows, and Optimization design.
