Standard U.S. Navy fiber optic assemblies require that the fiber be bonded to the connector using an adhesive that is labor intensive and heat controlled (MIL-A-24792). Advanced Material Systems (AMS) proposes a study that could solve this problem through the development of an adhesive system that would cure at room temperature in less that 3 minutes and yet meet all of the in-service req ...

The standard technique for the recording of telemetry data in range operations has been instrumentation tape recording. This has provided the capability for recording data at high data rates for extended periods of time. While convenient for recording, this technique suffers drawbacks in processing and playback of the data. Due to the serial nature of the medium, no capability exists for near-re ...

THIS PROPOSAL IS TO USE OPTICAL FIBER GRADED-INDEX (GRIN) ROD LENSES TO DEVELOP A WEAPONS SIGHT THAT HAS MAGNIFICATION, A BRIGHT IMAGE, REQUIRES THE EYE TO ONLY FOCUS AT ONE DISTANCE, IS RUGGED, IS ACCURATE, IS SIMPLE, IS SMALL, IS USER FRIENDLY, AND IS COMPATABLE TO BE MOUNTED ON EXISTING WEAPONS. THE PROGRAM INCLUDES VALIDATING THE CONCEPT, FABRICATING A TEST UNIT, AND TESTING THE UNIT ON A M16A ...

The objective of the Phase I effort is to demonstrate an experimental/numerical technique for formulating penetration equations and identifying pertinent material parameters to be used in those equations. Although penetration equations for isotropic metals are well developed, such equations are not readily applicable to anisotropic laminated composites, because composite failure is dominated by br ...

Astralux is developing heterobipolar transistors (HBT) using a SiC base. This device operates above 500 C with a current gain in excess of 100. Most of the effort went into design, technology, and characterization of these devices. To make the HBT into a commercial product, the technology of contacts and packaging must be developed. This proposal considers a joint project with NAWCAD and a pac ...

Astralux, having recently made the first transistor structure to operate above 500 C with a current gain exceeding 100, proposes to explore the limitations of the transistor's power handling capability. At room temperature, this transistor carries a current density one order of magnitude higher than commercial silicon power transistors. Also it is proposed to study the maximum frequency at which ...

Digital Wave Corporation proposed to develop a novel nondestructive testing (NDT) system for high speed acquisition and analysis of wide band acoustic emission (AE) waveforms. The system will provide the capability to detect, identify and locate crack growth in loaded steel structures. This system will incorporate the new high fidelity sensor developed by the Federal Highway Administration and a ...
