Overview of the DoD HPCMP Hypersonic Vehicle Simulation Initiative

摘要

Simulation of hypersonic vehicles requires the inclusion of multiple scientific aspects that are not currently modeled appropriately, or are not included at all, in most simulation codes. These aspects include: combustion physics, turbulence and transition, fluid-thermal-structural interactions, non-equilibrium chemistry, shock-boundary layer interactions, and ablation. Without the inclusion of these aspects of hypersonic flight (either through physics-based prediction or appropriate modeling), simulation of hypersonic vehicles is deficient and cannot properly provide support to the development and acquisition of hypersonic vehicles. In order to improve the national capability in hypersonic vehicle RDT&E, a Hypersonic Vehicle Simulation Institute is being established by the DoD High Performance Computing Modernization Program. The institute will follow a multi-pronged, multi-year approach to address these shortcomings in hypersonic vehicle simulation.
