New Three-Dimensional Inverse Method for High-Speed Vehicle Design

摘要

An inverse design method for fully three-dimensional supersonic and hypersonic bodies was developed for computer codes based on the Euler equations. The method is designed to be easily incorporated into existing analysis codes. The aim of the method is to provide the aerodynamic designer with a powerful tool for design of aerodynamic shapes of arbitrary cross section. Convergence acceleration techniques were developed and applied successfully to three-dimensional test cases. A three-dimensional body geometry modification method was developed with a new concept for the three-dimensional body slope angle. Examples are presented applying the method to a nonaxisymmetric fuselage-type pressure distribution and a cambered wing-type application. The method performs equally well for both nonlifting and lifting cases.
