Applications of and recent improvements to the AIRPLANE program (developed by Jameson and Baker) are presented. This unstructured-mesh Euler method is capable of solving the inviscid transonic flow about complex three-dimensional aircraft configurations. Preliminary validations for the ONERA-M6 wing are made with comparisons to test data and a structured-mesh Euler code. Geometric capabilities of the present method are illustrated with solutions about simple, semi-complex and extremely complex aerodynamic configurations. Post-processing techniques for unstructured-mesh solutions are also presented. Computational resources and manpower requirements are benchmarked for the ONERA-M6 wing and a generic MDC Tri-Jet transport; the computers utilized for this survey include CONVEX, CRAY, Hitachi and IBM.
