The current development of an electric power generation system for the More Electric Aircraft (MEA) is based on a low-risk extension of existing three-phase, switched reluctance machine (SRM) technology. This research program proposes to study an alternate two-phase SRM and its associated power-conditioning converter. By the nature of the proposed machine, it has 50% of its stator coils active at ...

Complex engineered systems involve a broad spectrum of technologies and interactive subsystems that must work synergistically in order to achieve the mission goals. The design of such complex and large-scale systems necessarily involves the collaborativeefforts of numerous geographically dispersed groups and design teams associated with private companies, government laboratories, and/or universiti ...

This research will determine extent and nature of the neutralization of bacterial spores when they are exposed, for very short times to high temperatures, pressures, and chemicals important in Agent Defeat weapons.. An exposure system will be constructedcapable of providing the ultra-short exposure times (on the order of ms) that are characteristic of bomb explosions and will be capable of exposi ...

CFDRC proposes to develop a numerical simulation tool uniquely capable of modeling spray cooling concepts for micro-gravity applications. The tool will include effects that are critical in microgravity and cannot be thoroughly investigated using gravitydominated ground-based experiments. The research will rely heavily on the tool to better understand the physics of spray cooling under micro-gravi ...

Development of combined Air-Turbo-Rocket(ATC/Scramjet component technology suitable for numerous USAF propulsion missions is proposed. Preliminary component design will focus on attaining fully throttleable boost and sustain thrust, vehicle speeds from Mach 0 to 8, and range as required. Activities during Phase I include: (1) Generator of an ATR/Scramjet system and component analysis methodology b ...

Reducing the cost of launching payloads into low earth orbit by a factor of 10 or 100 requires revolutionary changes in launching architectures. The Laser Lightcraft holds the potential for such savings by placing the bulk of the propulsion system on theground by using a ground-based laser to provide the impulse for lifting the payload. Attitude control for the Lightcraft is critical. This Phas ...

Given two closely related pieces of software X and Y, where Y differs from X through a number of small but important (from a security point of view) modifications that were done to Y, the

The goal of this program will be to investigate the issues associated with the development of a cognitive nuclear, biological and chemical threat data correlation and munitions effects analysis support system that is capable of supporting both training andoperational deployments. BRC is a major support contractor for the Army Corps of Engineers Engineer Research & Development Center (ERDC). ...

This Research and Development (R&D) effort will produce an architecture and prototype for performing quick-look analysis of Electromagnetic (EM) Compatibility (EMC) using Modeling and Simulation (M&S) technologies. The target domain will be aircraftsustainment and will focus on the insertion of commercial-off-the-shelf (COTS) technologies into existing aircraft. COTS technologies provide a cost- ...
