We will demonstrate the feasibility of a new type of airblast pressure sensor which will provide valid overpressure histories for airblast waves travelling in directions up to 90 degrees or more to the direction with which the sensor is aligned. Our specific technical objectives for Phase I are: 1) to develop a quantitative sensor design for assessment of feasibility, 2) to predict the expected p ...

THE OBJECTIVE OF THE PROPOSED WORK IS TO USE ADVANCED THEORETICAL AND COMPUTATIONAL TECHNIQUES FOR STUDIES OF HYPERSONIC BOUNDARY LAYER STABILITY AND TRANSITION TO TURBULENCE. THESE STUDIES WILL ENHANCE OUR UNDERSTANDING OF THE TRANSITION PHENOMENA AND THUS HELP PREDICT AND CONTROL TRANSITION WITH A HIGH DEGREE OF CONFIDENCE. TO ACHIEVE OUR GOAL, WE USE LINEAR STABILITY THEORY, SECONDARY INSTABILI ...

A NEW APPROACH TO ALKALI BATTERY DEVELOPMENT, WHICH CAN SATISFY THE DEMANDING HIGH RATE, HIGH SPECIFIC ENERGY SPACE MISSION REQUIREMENTS, IS PROPOSED. THE PROPOSED APPROACH OFFERS SPEPCIFIC ENERGY PERFORMANCE COMPARABLE TO THE BEST RECHARGEABLE LITHIUM BATTERY CHEMISTRIES CURRENTLY UNDER DEVELOPMENT, WITH SUBSTANTIAL INCREASES IN SPECIFIC POWER. THIS PROPOSAL DESCRIBES A PHASE I BATTERY CONCEPT FE ...

The Government needs a process that develop Form, Fit, Function, and Interface (F3I) specifications for legacy electronics, even when no or almost no design information is present. The process must succeed even when only hardware samples and test information are available. The proposed effort will develop a process by which F3I test requirements can be successfully re-engineering from legacy dat ...

Most E-O sensors operate in the visible and the near infrared. These sensors such as silicon and CCD arrays are very well developed resulting in high resolution and low cost. However, these sensors are limited to a spectral response of 900 to 1000nm. The mixing laser (MIXL) uses a non-linear material doped with lasing ions to create a self frequency summing or difference frequency mix ...

We propose to design and fabricate an optical filter that can be tuned continuously from 1.5 um to 2.5 um with a linewidth less than 1 nm. Our system consists of 2 separate filters that can each be electronically tuned. One provides a large free spectral range, and the other provides a narrow linewidth.

THIS OBJECTIVE OF THIS PROJECT IS TO DEVELOP AND BUILD A PROTOTYPE OF A DC TO DC VOLTAGE CONVERTER TO BE USED IN ELECTRONIC FOIL INITIATOR APPLICATIONS. THE DC TO DC CONVERTER WILL WORK AT 80% EFFICIENCY USING CURRENT MODE CHARGING. THE WORKING VOLTAGE WILL BE 2.5 KV WITH AN OVERALL POWER DENSITY OF 25 WATTS PER CUBIC INCH. THE DC TO DC REQUIRES AN DYNAMIC ENVIRONMENTAL INPUT FOR CHARGING. THIS UN ...
