Award Data

The integrity of rubber-to-metal bonds is an area of reliability concern, particularly in systems that are exposed to the harsh conditions of the marine environment. Accelerated life testing (ALT) is a technique used to obtain reliability data in a compressed time frame, allowing lifetime performance predictions and failure mode analyses to be made prior to equipment installation. By performing ac ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

LOW VULNERABILITY AMMUNITION (LOVA) PROPELLANTS ARE FORMULATED TO RESIST IGNITION BY VARIOUS THERMAL THREATS AND TO BURN POORLY AT ATMOSPHERIC PRESSURE. THESE FEATURES ALSO MAKE RELIABLE IGNITION IN GUN SYSTEMS A DIFFICULT PROBLEM. THE PROPOSED PROGRAM IS DESIGNED TO PROVIDE EXPERIMENTAL AND ANALYTICAL PROCEDURES BY WHICH THE PHYSICAL AND CHEMICAL ENVIRONMENTS THAT FOSTER IGNITION MIGHT BE IDENTIF ...

Microbiologically influenced corrosion (MIC) of most industrially utilized alloys, including those used in many Naval installations, is well established. However, the diagnosis of MIC type corrosion is often difficult to make using the techniques commonly employed requiring large amounts of tiem and money and "expert opinion". Ther is a need for a less subjective indicator of MIC. The work of seve ...
