We propose a Yb:SFAP laser system, using a novel resonator scheme, that will provide over 1 J per pulse output at 100 Hz at high efficiency, in a package far more compact, lower mass and efficient that conventional systems. The high-pulse-energy poweroscillator architecture is especially suited to space platforms where weight, volume, cooling and efficiency are particularly important. The propos ...

Advanced IRCM lasers and systems, currently in development, require mid-infrared semiconductor lasers with very non-standard design parameters. The proposed effort will investigate the performance of commercially grown GaSb based materials and optimizetheir performance for use in unique laser transmitter designs, which will be directly traceable to future IRCM systems. The proposed mid-infrare ...

The objective of this proposal is to demonstrate methods for extending the Battlespace Infosphere to mobile platforms using optimized COTS technologies. The 1999 USAF Scientific Advisory Board report titled Building the Joint Battlespace Infosphereidentifies the eXtensible Markup Language (XML) as one of the most promising technologies for representing JBI information objects. Indeed, many DoD use ...

Ascension Technology proposes to develop a fast, new six degrees-of-freedom tracker, phasorBIRDTM, immune to cockpit and helmet scatterers of magnetic/electrical field energy. It will integrate seamlessly with training simulators, aircraft, tanks, andcombat air operations centers (CAOCs). Design features will enable it to exceed static accuracy and repeatability of the best magnetic trackers while ...

Moore's law states that computing performance doubles every 18 months. While this has held true for 40 years, it is widely believed that this will soon come to an end. Increases in performance coincide with decreases in scale on the computer platform. Dueto the small scale of computer components, both interference effects are starting to play a role in the development of new components. This impli ...

This proposal describes the design and creation of an interface for controlling multiple UAVs in a real-time situation. Named the Uninhabited Air Vehicle Management Interface (UAVMI), it is centered on a 3-dimensional graphical representation of theoperational geographic area. The operator is able to move a 3D cursor around within this geographic volume, selecting groups, paths, and targets in 3D ...

There is a significant opportunity to meet higher upper stage engine performance levels by combining a much higher chamber pressure expander cycle engine with advanced technology turbomachinery. The Phase II SBIR goal is to provide a solid foundation foran upper stage engine design focused on IHPRPT goals. Three main Phase II technical objectives must be met to achieve this goal: 1) finalize th ...

Lateral analysis of multi-level or multi-spool turbofan and turbojet engines has been regularly performed for more than 30 years by commercial engine manufacturers. Similarly, engine bearing designers also possess the ability to perform detailed analysisof bearing for the purpose of calculating operating characteristics (e.g., component operating temperatures) and determine statistical distribut ...

Developing new techniques for combustion chamber cooling are critical to increasing engine life to 60 missions or greater. Concepts NREC will explore several chamber cooling options that minimize or eliminate coking increasing engine chamber life withoutsacrificing performance or adding cost. The proposed Phase I study will investigate methane as the hydrocarbon propellant for cooling along with ...

Evaporative spray cooling systems are perhaps the only systems capable of the high power density thermal control anticipated for future spacecraft. However, evaporative spray cooling in the micro-gravity environment poses particular challenges foreffective system design because of the complications imposed by the
