Aerospace Vehicle Signature Modeling Technologies

TECHNOLOGY AREA(S): Air Platform, Information Systems, Sensors OBJECTIVE: Develop computational fluid dynamics (CFD) software tools to extend modeling capabilities, including turbulence, chemically reactive flow, radiative heat transfer and acoustics, for the prediction of aerospace vehicle signature phenomenology beyond the current state of the art. DESCRIPTION: Seek CFD software tools that accurately model flight and environment conditions encountered by vehicles operating in the Mach 10 to Mach 20-plus regimes at upper stratospheric altitudes. Novel advanced computational technologies are required to extend current models and simulations of aerospace vehicles to support these high-Mach-number flight regimes. Modeling should include aero-thermal flow and associated atmospheric phenomena (heating, plasma, shock waves, etc.) to yield cross sections and signature predictions. Model output should support including radar (HF through SHF radio frequency) electro-optic/infrared, and acoustic sensors. Model documentation should include relevant physics and credible validation. PHASE I: Develop concepts for enhancing existing CFD tools to model aero-thermal effects on aerospace vehicles in the extended performance envelope for signature prediction. Demonstrate credibility of proposed models and validation approaches. The contractor should identify the strengths/weaknesses associated with alternative solutions, methods, and concepts. PHASE II: Develop and validate CFD tools to support aerospace vehicle signature predictions. Provide a performance analysis of the planned CFD capability, complete executable code for the developed modeling and/or signature prediction toolset, and an operator manual. Develop and implement verification and validation of the toolset. Coordinate development efforts with the government to ensure product relevance and compatibility with missile defense projects and government-owned-and-operated information technology. PHASE III DUAL USE APPLICATIONS: Collaborate with existing CFD and signature tool developer/users on integration of product(s) into a missile defense application. Update toolset to accommodate new technology advances in aerospace vehicle design modeling. Transition the technology to the appropriate customer for integration and testing. KEYWORDS: Flight, Computational Fluid Dynamics, Modeling, Signature, Aerospace Vehicle, Midcourse, Tracking, Prediction POINT OF CONTACT: Dr. Ashley Lindley, Phone: 256-450-4368, Email: ashley.lindley@mda.mil
