APAS is an interactive computer program that allows a user to quickly estimate the aerodynamic characteristics of aerospace and aeronautical vehicles throughout the speed range using a single geometry definition. This report documents the major differences between the high speed analysis portion of the APAS and the Mark III version of the hypersonic arbitrary-body program from which it has evolved and compares convective heating and viscous drag results from the APAS with CFD results, experimental data, and flight data.
