Recent advances in electromagnetic technology clearly lend themselves to application in space-based data storage/retrieval systems. Commercial data storage systems provide low cost, long-life operation and strong logic/control systems, but employmechanical bearings that limit their resistance to shock and life expectancy. A similar system ruggedized for space via integrated magnetic motor-bearing ...

Mitigation of Single Event Upset (SEU) to electronic devices and components has traditionally been and expensive problem to overcome. Dramatic improvements in electronics technology have rendered many prior SEU solutions ineffective and have created theneed for more advanced and innovative design tools. One of the more promising SEU solutions has been triple modular redundancy (TMR), where each ...

This project is directed towards the refinement and demonstrationof a robust high-temperature nonskid coating that can withstandrepeated flight operations associated with the AV-8B Harrieraircraft on the decks of Wasp-class Amphibious Assault Ships(LHDs). The Fleet has filed a series of Quality DeficiencyReports, Hazardous Material Reports, and Casualty Reports, whichdocument nonskid failures rel ...

The goal of this project is development of an acoustic system for imaging buried objects and underground geological features like bedrock layers, underground stream channels, and fracture zones. Current technology for imaging these features relies on theuse of electromagnetic radiation and suffers from limited spatial resolution and limited penetration depth in areas of high soil conductivity. Dur ...

Future DoD cryogenic cooling applications include space missions with relatively large cooling demands. These include space-based lasers, orbital transfer vehicles requiring cooling of stored fuels, and space-based platforms using large arrays of infrareddetectors. Loads for these applications will range from several watts to tens of watts. Temperatures of interest are between 10 and 100 K. Cu ...

In Phase-I, a Fast Pattern Recognizer (FPR) System was evaluated as a future processor candidate for Navy fast-reaction, supersonic, stand-off weapons. The FPR will autonomously detect, identify, correlate, and track complex ship and land targets inhostile, high-clutter environments in real time. Because image correlation is computationally intensive, real-time processing must be accomplished by m ...

Imaging LADAR systems are critical to autonomous guided munitions. The objective of this program is to demonstrate a solid-state, eye-safe, 3-D staring imaging LADAR receiver. This state-of-the-art focal plan array LADAR receiver will combine a 1.55micron photodetector and an internal gain photodetector with a 3-D imaging readout circuit using an innovative manufacturing process. The resulting ...

LOW SPEED, TWO PHASE (VAPOR-LIQUID) FLOW REGIMES ARE IMPORTANT TO SEVERAL SIGNIFICANT HEAT TRANSFER PROBLEMS IN SPACECRAFT. LOW SPEED FLOW RATES ALSO CREATE THE MOST GRAVITY-AFFECTED FLOW REGIMES. HIGH SPEED FLOW RATES CREATE FLOW REGIMES THAT ARE AFFECTED LITTLE BY GRAVITY. FEW STUDIES EXIST WHICH GIVE AN OVERVIEW OF FLOW REGIMES IN ZERO GRAVITY. IN PARTICULAR, FEW STUDIES HAVE ATTEMPTED TO USE R ...

IN THE PROPOSED RESEARCH THE FEASABILITY WILL BE ESTABLISHEDFOR DEVELOPING A LOW-COST EXPENDABLE TRANSDUCER MOUNTED IN ANATIONAL WEATHER SERVICE TYPE RADIOSONDE TO MEASURE VERTICALPROFILES OF SUPERCOOLED LIQUID WATER. THE TRANSDUCER IS BASED UPON A WIRE WHOSE NATURAL VIBRATION FREQUENCY VARIES ACCORDING TO THE AMOUNT OF ICE COLLECTED ON THE WIRE. THE RESEARCH WILL EXAMINE THE EFFECTS ON THE THE RE ...

THERE ARE NUMEROUS APPLICATIONS WHERE THE THERMAL AND ELECTROMAGNETIC PERFORMANCE OF PURE METAL CONDUCTORS CAN BE APPRECIABLY ENHANCED BY COOLING WITH LIQUID HYDROGEN. ONE SUCH APPLICATION INVOLVES COOPER AND TUNGSTEN CONDUCTORS OF ELECTROMAGNETIC LAUNCH SYSTEMS COMMONLY KNOWN AS RAIL GUNS. THIS PROPOSAL ADDRESSES A NOVEL CONCEPT TO ENHANCE THE PERFORMANCE OF RAIL GUNS BY INCREASIG THEIR EFFICIENC ...
