SRD will develop a miniaturized atmospheric gas sensor array and design a gas analyzer (sensor analyzer module, SAM) capable of accurately detecting and autonomously monitoring critical atmospheric gases in enclosed spaces. In this Phase I effort, SRD will use its current, existing technology (miniaturized sensor platform, proprietary SMO sensor coatings and advanced signal processing algorithms) ...

Positioning and navigation have become a mainstay of everyday life in the U.S.; applications of interest include navigation of vehicles of all kinds, infrastructure mapping, and safety of life systems. Many of these recent applications have become possible through the GPS. With the recognized vulnerabilities of GPS, it is evident that equivalent backup systems must be developed. One possible so ...

MAJOR AIDS TO NAVIGATION (ATON) ARE ESSENTIAL SIGNPOSTS FOR SAFE PASSAGE ALONG COASTAL AND OFFSHORE SEAWAYS. PRESENTLY, THEIR SIGNALS ARE POWERED BY ON-SITE ENGINE GENERATORS REQUIRING CONSIDERABLE AND COSTLY MAINTENANCE. ATON AUTONOMY WILL BE GREATLY INCREASED WITH DEEP DISCHARGE BATTERY TECHNOLOGY PROVIDING THAT ON-SITE CHARGING SOURCES ARE USED. AMONG NATURALLY AVAILABLE SOURCES, THE UNCEASING ...

THE PROPOSED PROGRAM EXAMINES OPPORTUNITIES FOR LIGHTWEIGHT CONTAINMENT STRUCTURES IN AIRCRAFT AND ROTORCRAFT AND SEEKS TO DEVELOP FIBER REINFORCED MATERIALS AS THE ENERGY ABSORBING CORE OF POTENTIAL CONTAINMENT DESIGNS. THE PROGRAM BEGINS FROM BASELINE DESIGNS FOR FAN CONTAINMENT WHICH EMPLOY PLAIN WEAVE KEVLAR LAMINATES TO ABSORB BLADE FRAGMENT ENERGIES. VARIOUS ADVANCED FIBERS INCLUDING POLYETH ...
