The objective of this project is to extend the existing Message Translator and Validator (MTV) model's range of applicability for a variety of application areas and platforms. The MTV model is a scalable set of Ada code templates and generics that convert between external communication formats and application-specific data formats. In Phase I we will apply the Object-Connection-Update (OCU) model ...

During launching of regenerative liquid propellant guns, the projectiles and their components experience potentially damaging high pressure/high frequency oscillations. The purpose of this program is to develop the experimental and computational facilities to simulate these effects. The three major objectives to be accomplished in Phase I are: (1) To develop a method of inducing forced vibrations ...

Functional gradient materials (FGMs) have a microstructurally graded transition in composition (e.g. zirconia to a nickel based superalloy). The graded transition eliminates problems associated with a discrete interface such as poor mechanical strength and transport losses. They are being actively pursued by the engineering community, particularly in Japan, as a means of taking advantage of two di ...

The proposed program is to develop the use of aqueous biopolymers for the solid freeform fabrication of ceramic components. It will be a collaborative effort between ACR and Battelle PNL. PNL has expertise in colloidal ceramic processing and experience on utilizing biopolymers in ceramic slurries. ACR has already developed extensive software and hardware capability for solid freeform fabricatio ...

We propose development of a 'smart' optical preprocessor that installs as an integral part of the light gathering optics of first- or second-generation forward looking infrared imaging systems (FLIRs). This optical preprocessor is based on an advanced-art imaging acousto-optic tunable filter (aka, A-O filter). These newly-configured A-O filters are programmable to seek out specific spectral featur ...

The theoretical maximum energy product of intermetallic compounds Nd2Fe14B and Pr2Fe14B is as high as 64 M Oe at room temperature. However, the actual energy product achieved in the laboratory is ~50 M Oe and the best commercial magnets exhibit only ~45 MG Oe. The inability to fabricate magnets with energy products close to 64 MG Oe is caused in part by 1) an imperfect grain alignment and 2) the p ...

THE CURRENT FIVE-POINT MILITARY AVIATION RESTRAINT SYSTEM (FOR NON-EJECTION CREW SEATS) WHEN PROPERLY USED (I.E., TIGHTLY ADJUSTED), CAN PROVIDE GOOD OCCUPANT CRASH PROTECTION. THE RESTRAINT SYSTEMS ALSO INCLUDE AN INERTIAL REEL ON THE SEAT BACK WHICH IS DESIGNED TO LOCK THE SHOULD STRAPS AT THE ONSET OF A CRASH, IN THE SAME MANNER THAT THE COMMON AUTOMOBILE SEAT BELT INERTIAL REEL LOCKS WHEN JERK ...
