Numerical Simulation of Hypersonic Aerodynamics and the Computational Needs for the Design of an Aerospace Plane.

摘要

This Note records the results of a review and analysis of the status of the computational fluid dynamic (CFD) modeling techniques related to the National Aerospace Plane (NASP) operation. It was undertaken as a task in the study, The National Aerospace Plane (NASP): Development Issues for Follow-on Systems, performed within the Technology Applications Program of Project AIR FORCE. The research sought to evaluate independently the degree of uncertainty and the technical risk involved in predicting the NASP performance using numerical simulation of aerothermal and chemical/combustion processes. This Note covers the technical review portion and identifies the areas for research emphasis so that the predictive reliability of the NASP's potential performance parameters can be improved. This study should interest those concerned with the aerospace plane development in general, and hypersonic CFD modeling in particular.
