The design of Unmanned Aerial Vehicles (UAV’s) is a complex process of creating a reliable system of reasonable cost that can survive in hostile environments. Although UAV’s have unique aspects to them, similar goals can be found in almost any complex, competitive product. One aspect of the design of these systems that tends to be both difficult and poorly supported with available computer ...

75353-Low cost, self-powered wireless sensors that never require battery changing or other maintenance are needed for U.S. industrial production lines, in cars and buildings, and power generation systems. Systems of these sensors will enable a revolution in industrial efficiency, safety, and reduced maintenance costs. This project will develop a wireless sensor with an integrated vibration-power ...

The use of coated HT superconductors in the ac windings of electrical machines offers the possibility of much lighter electrical devices. To use these conductors at proposed high frequencies, present “as-manufactured” conductor geometries must be modified to reduce their ac loss by using fine filaments and other topologies). Equally important are more global winding losses requiring suitable ...

The main objective of this program is to develop a new class of high performance hard magnetic materials that will maintain an energy product of 30 MGOe or greater at temperatures up to 450 °C. These novel magnetic materials are greatly needed for the "more electric" airplanes and space vehicle applications where a high operating temperature is a strict requirement. The approaches to be used for ...

73189B03 I Upon transmitting or receiving messages, the classical network interface card (NIC) generates an interrupt to the operating system kernel and thus to the host processor, which must service the interrupt. As network speed increases towards 10 Gigabit Ethernet, the host can be tied down with interrupt latency. New Operating Systems (OS) Bypass systems (hardware and software) are needed ...

70558B02-II The control and dynamic operation of Fuel Cell/Turbine Hybrid power plants will require a synergy of operation between subsystems, increased reliability of operation, and reduction in maintenance and downtime. Furthermore, the control strategy of the power plant will play a significant role in system stability and in ensuring the protection of equipment to promote maximum life. Thi ...

Boron has significant potential as a high energy density ingredient in ramjet propellants and fuels. This is due to boron's high heat of combustion and low atomic weight. For a ramjet ducted rocket, theoretical volume specific impulses of 1600- 1800 sec g cm-3 have been reported for a fuel rich boron solid propellant, 45 % greater than the best hydrocarbon composition. Boron's high ignition tem ...
