Future gas turbine propulsion designs, in addition to incorporating variable geometrical engine features, will require controlling and integrating large power generation/extraction, as well as, managing thermal limits of the components. The engine contro...

Next-generation intelligent engines will operate at higher temperatures for increased efficiency and will migrate from centralized to distributed control. There is critical need for sensors for operation at ultra-high temperatures (3000F). Conven...

ABSTRACT: A range segment upgrade for Air Force satellite control network (AFSCN) will significantly improve system effectiveness via spectrum sharing and seamless interoperation. However, the upgraded system requires new capabilities such as real-time and accurate RF interference detection and mitigation, array antenna backlobe/sidelobe suppressions, accurate performance degradation prediction, ...

The U.S. Air Force is interested in developing hypersonic vehicles including reusable transport aircraft, cruise missiles, and unmanned systems. Hypersonic flight regimes result in multifaceted and very difficult design challenges that can be encapsulated into an aerothermoelastic problem, which is a complex interaction of structural, thermal, and aerodynamic mechanisms. When a flexible structural ...

The Air Force is interested in developing technology that would enable long duration hypersonic flight with reusable aircraft. Hypersonic flow presents many design challenges that can be encapsulated into an aerothermoelastic problem, i.e., a complex dyn...

ABSTRACT: We propose here a robust production-level high-order mesh generation software for complex geometries. High order accurate numerical methods are becoming increasingly popular in the present time and have demonstrated a great measure of success in efficient error-controlled simulations for a wide variety of important problems. A curved geometry and mesh generation system is essential in m ...

In this program, HyPerComp and University of Michigan have teamedtogether to develop a high-order grid generator for Euler and viscousmeshes. The grid generator is based on HyPerComps successful generalpurpose CAD2Mesh software and is being integrated with HyPerCompsHDphysics and U. Michigans XFlow DG high-order solvers. High-order gridgeneration methods are being implemented to accurately capture ...

The Air Force is seeking solutions for a sun-tracking millimeter wave radiometer to measure atmospheric attenuation over a high dynamic range. The V- and W- bands have rarely been used for space communications and telemetry applications, but rapidly increasing government and commercial bandwidth needs will require future solutions within these bands. Our team, comprised of experienced scientists, ...

ABSTRACT: Spectral Sciences, Inc. and Sandia National Laboratories propose a Metal Vapor Ionospheric Control System (MVICS) for on-demand turbulence suppression and control of ionospheric RF propagation. The system uses a lightweight, throttleable directional mechanism for controlled production and dispersal of artificial plasma into the space environment. MVICS relies on three innovations: a nove ...

ABSTRACT: Electro-optic/infrared (EO/IR) sensors are key to the mission success of future hypersonic vehicles. Although EO/IR sensors have been extensively used for subsonic flight regimes, the hypersonic flight regime creates new conditions and complexities with significant impact on optical sensors. These complexities include turbulent, high temperature gas that is in Non-Local Thermodynamic Equ ...
