    Lockheed Martin Astronautics has developed the Multifunctional Structure (MFS) concept as a new system for spacecraft design that eliminates chassis, cables, connectors and folds the electronics into the walls of the spacecraft. Concurrent engineering will be essential to integrate the electronic, structure, and thermal design. Design methodologies are in work to manage all power, grounding and sh... View full abstract»

    Starting and reversing times of less than 40 ms, torque ripple below ten percent and operational speeds over 5000 1/min. (rpm) can be achieved with our 6/4 prototype switched reluctance motor drive. The drive efficiency approaches 80 percent but it is currently limited by high switching frequency. Peak currents of 50 A are needed in the 4.2 kW machine. Experimental results of the prototype switche... View full abstract»

    In this paper we analyze the potential for CHP in US manufacturing. We use typical efficiencies of today's available CHP technologies to estimate the technical potential for the frozen technology case. We find that if manufacturers in 1994 had self-generated all their steam and electric needs with existing cost-effective CHP technologies, they could have reduced carbon equivalent (=12/44 carbon di...

    This paper describes the application of a simulation software and the comparison of its results with actual data recorded from operating ATC radars in S and L bands. Results obtained in an application on actual signals (relative to commercial aircraft echoes) collected from observations on the echo received at an ATC radar system are presented. These signals were recorded along many field experime... View full abstract»

    The Integrated Sensor System (ISS) program is defining an Open System Architecture (OSA) for Radio Frequency (RF) electronics, which represent the largest portion of an advanced aircraft's avionics flyaway cost. An integrated architecture is used to reduce costs in a number of ways, including time-sharing, centralization of resources, and reduction of the number of unique module types. The OSA app...

    The leading cause of worldwide aviation fatalities comes from inadvertently flying a perfectly operating aircraft into the ground or water. This type of accident is referred to as Controlled Flight Into Terrain (CFIT). Statistics show that introduction of the Ground Proximity Warning System (GPWS) into the scheduled air carrier turbojet fleet has been accompanied by a dramatic drop in the frequenc...
