Abstract

A model was designed and built using The Mathworks’ SIMULINK to simulate the aerodynamic heating of gun-launched projectiles ballistically flying at hypersonic velocities in the lower and upper atmosphere. The model is based on NASA Ames real-time aerodynamic heating and surface temperature calculations for hypersonic flight simulation. Developed model was used to predict the stagnation and surface temperatures of three conceptual projectiles intended for use as Navy Area Theater Ballistic Missile Defense (NATBMD) training targets.
