High-Performance Computing and Test and Experimentation
Abstract
Today, scientists and engineers are just beginning to use science-based simulation to virtually design, test, and evaluate new ideas and systems. Organizations all across the Department of Defense (DoD) are changing their business processes to take advantage of simulation-based processes enabled by supercomputers and parallel software. Many members of the T&E community saw the potential benefits nearly a decade ago, and today these T&E leaders are working with improved capabilities. For example, the use of supercomputers and science-based software has transformed the stores certification process. Air Force and Navy test engineers are using supercomputers to augment current ground testing techniques and to reduce open-air flight-testing, resulting in faster stores certifications and reduced certification costs. Computational science, specifically computational fluid dynamics (CFD) running on supercomputers, is used to predict aerodynamic loads for aircraft stores before, during and after release. This capability has been used extensively in certifying new aircraft-weapons combinations prior to deployment in Afghanistan and Iraq. The Arnold Engineering Development Center used its high-performance computing (HPC) resources to assist in the design of the Joint Strike Fighter (JSF) engine inlet. Using CFD, Lockheed-Martin was able to model and analyze the complex flows at the inlet, thus supporting a quick design and test cycle. HPC also has been used to assist in the development of the JSF Key Performance Parameters for the Operational Requirements Document. Using supercomputers at the ARL Major Shared Resource Center, simulations were run to evaluate add-on blast protection for the Stryker wheeled vehicle to lessen the danger from improvised explosive device blasts and fragmentation. The Javelin Integrated Test and Simulation Network (JITSN) is a hardware-in-the-loop test facility, made possible through the use of supercomputers.
