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 ...

The enabling solid state semiconductor technology in radar systems supporting the U. S. Army's ballistic missile defense program increases its vulnerability to the effects of high power, fast rise-time EMP, HPM, and UWB pulses. In recent years, significant advances in the technology used to produce these pulses have been made in the United States and abroad, increasing the need for effective prot ...

Thrust Vector Control (TVC) systems offer advantages such as reduced complexity and fewer thrusters relative to many other divert and attitude control (DAC) systems. Proposed is the development of a novel TVC system to provide miniature DAC capabilities for a wide range of mono-prop and bi-prop missile propulsion systems. A primary benefit that the proposed TVC concept offers relative to systems ...

BIPOLAR BATTERIES CAN, IN PRINCIPLE, YIELD ORDERS OF MAGNITUDE HIGHER SPECIFIC POWER THAN CONVENTIONAL, PARALLEL PLATE BATTERIES. SUCH BATTERIES BEGIN TO HAVE PERFORMANCE CHARACTERISTICS SIMILAR TO CAPACITORS AND COULD POSSIBLY BE USED TO REPLACE CAPACITOR FOR SOME APPLICATIONS. BATTERY PERFORMANCE OF BETWEEN 5 AND 2 A/CM2 AT 1.0 V CELL POTENTIAL FOR A TIME PERIOD OF 500 MICROSECONDS WITH ELECTROD ...

THE DETECTION OF NEUTRONS NORMALLY IS A PROBLEM BECAUSE OF THEIR LACK OF CHARGE AND THEREFORE WEAK INTERACTION WITH MATTER. NEUTRON INDUCEDCONDUCTIVITY CHANGES OFFER THE OPPORTUNITY FOR THE DEVELOPMENT OF A DIRECT MEANS OF MEASURING NEUTRON FLUENCES. DEVELOPMENT OF ORGANIC POLYMER-BASED FAST AND THERMAL NEUTRON IS BEING INVESTIGATED AND IS ANTICIPATED TO BE CAPABLE OF DIRECTLY MEASURING NEUTRON FL ...
