Power electronic converters are essential in every MDA vehicle, with use in critical systems ranging from electric power management applications, to power distribution, to on-board servo motor/actuator drivers. Advancing state-of-the-art power electronics technologies through the use of SiC semiconductors will produce significant savings across the board in almost all areas of MDA power management ...

WORKERS AT BRIGHAM YOUNG UNIVERSITY, BIPOLAR TECHNOLOGIES, HAVE DEVELOPED A MATERIAL FOR USE AS A BIPOLAR ELECTRODE SUPPORT WHICH WILL RESULT IN MORE LIGHTWEIGHT, LONGER LIFE BATTERIES. THE ELECTRODE SUPPORT IS A COMPOSITE MATERIAL COMPOSED OF LOW SURFACE AREA CARBON/POLYMER COMPOSITE MATERIAL WHICH HAS LOW ELECTRICAL RESISTANCE, CHEMICALLY STABLE, AND HAS LOW ACTIVITY FOR OXYGEN EVOLUTION, AN UND ...

INTEGRATED SYSTEMS INC. (ISI) AND INDUSTRIAL SOLID PROPULSION INC. (ISP) HAVE JOINTLY DEFINED A CONCEPT FOR A VALVELESS SOLID PROPELLANT DIVERT CONTROL OF KINETIC ENERGY PROJECTILES. ISP AND CONSULTANT DR. BOB GEISLER EVOLVED THE MULTIPULSE PROPELLANT GRAIN AND DUAL-ENDED IGNITER DESIGN OUT OF ISP'S SMALL ROCKET MOTOR TECHNOLOGY. ISI PROVIDED THE GUIDANCE AND CONTROL KNOWLEDGE NECESSARY TO DETERMI ...

A compact x-ray laser driver with a high repetition rate is the subject of this phase I project. Most existing x-ray laser drivers are huge (1000s of square feet of floor space), expensive ($10,000,000+), have a low repetition rate (1/hr), are complex and require several PhDs to keep them working. Thus applications of present x-ray lasers are limited. In contrast, the proposed laser will occupy on ...

Miniature adsorption refrigeration systems capable of cooling as low as -60 degrees Fahrenheit without fans for heat rejection are being developed. When used with computers and electronics packages, advantages include 40% higher processing speed with key chips operating at low temperature, better reliability with hermitically sealed chassis and no hot spots, and low noise by elimination of fans. O ...

Sarcos is currently developing a technology that can lead to low-cost millimeter-scale gyroscopes, multi axis inertial sensors, and very compact laser scanning devices. This technology, called Micro Disk Systems (MDS), is based on levitating a small disk above a VLSI substrate using electrostatic fields. AC stabilization of the fields ensures that the disk position remains suitable, and field-base ...

THE COOLING REQUIRED FOR THE PROPER OPERATION OF VARIOUS SENSORS AND INSTRUMENTS IS A KEY PROBLEM IN SPACE-BASED FACILITIES. A NOVEL CONCEPT HAS BEEN DEVELOPED AT LONE PEAK ENGINEERING BASED ON THE COMPRESSION OF A GAS TO HIGH PRESSURES USING A SOLID ELECTROLYTE COMPRESSOR. RAPID EXPANSION OF THE COMPRESSED GAS (JOULE-THOMSON EFFECT) CAN BE USED TO COOL SPACECRAFT INSTRUMENTS AND EQUIPMENT. SOME O ...
