DCS has extensive experience in model verification and validation through our support to various weapons programs, on the ground and in the air. We specialize in model development (e.g. aerodynamic databases and autopilot and/or ground control equipment). For subsonic through hypersonic flight regimes, we plan and conduct aerodynamic and propulsion testing (full-size and subscale wind tunnel testing), ground testing (Hardware-in-the-Loop [HIL]/Software-in-the-Loop [SIL]), and support flight testing. We analyze system performance in the areas of aerodynamics, propulsion, guidance, navigation, and control. As a result, numerous weapons models, used for mission planning, flight certification, airworthiness analysis, and performance specification compliance analyses have been improved and accepted for use by the Air Force, Navy, and other government agencies. As more and more reliance is made on simulations in lieu of open air testing, rigorous V&V efforts save time and money. DCS has been used as a trusted agent for modeling and simulation and V&V of weapons such as small diameter bombs, joint air-to-surface standoff missiles, long range anti-ship missiles, arrows/bolts, joint standoff weapons, high-speed antiradiation missiles, and many others.
