GoGames will be a tablet-based multiplayer role-play game for middle school social studies classrooms and will focus on topics in civics. GoGames is intended to enable more efficient and effective implementation of traditional civics interventions by replacing static paper content and training manuals with dynamic interactive content and key information for gameplay. Modules will include LawMaker, ...

ABSTRACT: This proposal addresses the need for solutions that enable higher levels of spacecraft autonomy to reliably maintain operational capabilities. Random hardware faults and hostile threats necessitate autonomous systems capable of responding quickly and effectively to these threats and unexpected events. The proposed research will develop an autonomy software architecture that enables evol ...

ABSTRACT: The objective of this proposal is to achieve an operational capability to produce daily forecasts of the extended extreme ultraviolet solar spectral irradiance (XUV/EUV/FUV SSI, hereafter EUV SSI) by delivering quantitative expectations of the EUV SSI at high-spectral resolution for every day in the period of at least a week after the day the forecast is issued. The forecasted EUV SSI i ...

ABSTRACT: Modern military space systems use high specific impulse (Isp) propulsion systems to provide efficient station keeping and large delta-V orbital maneuvers. A multi-mode propulsion system utilizes a single propellant such as AF-M315E to provide high thrust as well as a 1000-4000 s Isp. By utilizing the same propellant in multiple thrusters an entire new range of mission operations are pos ...

ABSTRACT: Residual stresses can be created in engineered components by most common fabrication processes (e.g., welding, joining, machining, casting, heat treating, press fitting, etc.). They are of particular concern to the aerospace industry because they are difficult to measure and can lead to premature failure of flight-critical components. There are several established methodologies for ch ...

ABSTRACT: Flow Modeling and Simulation, LLC (FMS), proposes to develop a computational software tool, herein designated AUG3D, that is intended to provide physics-based, multi-level, validated computational simulations of turbine engine component flow fields, particularly those associated with thrust augmentors, i.e., afterburners. This tool will be ideally suited for closely integrating physica ...

ABSTRACT: We propose to develop for the Air Force a high-efficiency Waste Heat Removal System (WHRS) that removes large amounts of waste heat from aircraft with negligible impacts on signature and aerodynamic performance. Our WHRS absorbs heat from aircraft thermal loads, including a Thermal Energy Storage (TES) system that absorbs and stores heat from the cooling system of a High Energy Laser ( ...

ABSTRACT: The efficient coherent beam combination of a master oscillator power amplifier (MOPA) system requires a reduction in non-linearities of the power amplifier sections. Fiber non-linearities, such as stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS), provide an upper limit on the operating power of kW-class fiber laser systems. These non-linear effects can be redu ...

ABSTRACT: Coordinate Registration (CR) of OTHR targets requires accurate real-time ionospheric modeling coupled with HF propagation calculations to convert radar-measured target signal delays and beam steers to geographical position. Our team is the developer of one of the most sophisticated ionospheric data assimilation capabilities currently in existence, GPSII (GPS Ionospheric Inversion; pron ...

ABSTRACT: nLIGHT proposes the development of of an all-fiber, master oscillator power amplifier (MOPA) configuration that will meet the Air Force requirements for a 10 mJ, 300 ns pulsed laser source. With the exception of the output power amplifier fiber, this device will be based on commercial off the shelf (COTS) components. This proposal is based on an Er-doped fiber amplifier that is res ...
