It was found that CFD++ produced the lowest errors of all the tools tested, highlighting the applicability of the tool to all tested flow regimes, and is recommended for use where the highest fidelity solution is desired and the result is not highly time critical. The results for Cart3D showed that it may be used to obtain a solution for supersonic cases where a small margin for error in the results is acceptable. However, the accuracy was lower for other flow regimes, especially the transonic regime where Cart3D produced erroneous results. Missile Datcom produced erroneous results for the non-conventional geometry tested, however it was able to produce medium fidelity results for conventional air to air missile shapes. The ability of Missile Datcom to produce results very quickly highlights its utility for quick-look analysis of conventional air to air systems.
