X-ray computed tomography (CT) is widely used in defense, aerospace, and industrial applications. CT provides flaw detection, density measurement, accurate dimensions, morphology, assembly verification, material property analysis, and other vauable information. However, a major limitation of CT has been the inspection time required for 100% coverage of an object, since a single slice through the o ...

COALITION TECHNOLOGIES, LTD., (CTL) RESEARCH HAD IMPROVED A SIMPLE GAS PHASE TREATMENT (SULFONATION) OF WASTE RUBBER AND PLASTICS. RESULTS FROM LABORATORY SCALE EXPERIMENTS DONE AT MICHIGAN STATE UNIVERSITY HAVE SHOWN THAT CONCRETE MADE FROM SULFONATED RUBBER AND PLASTIC PROVIDED BY CTL HAS IMPROVED IMPACT RESISTANCE AS MEASURED BY ASTM STANDARD TESTS. IN MANY CASES, WASTE PLASTICS AND RUBBER ARE ...

Laser chemical vapor deposition (LCVD) silicon nitride fiber growth is proposed, to make fibers which have the strength and oxidative stability required for advanced high temperature structural applications. This method has been demonstrated to yield continuous, high strength fibers of materials such as boron, silicon, and others, with diameters in the range 10-30 microns, tensile strengths up to ...

The proposed effort analyzes five spectral imaging radiometer concepts with the goal of developing an infrared spectral imaging radiometer (IRSIR) for use in high performance aircraft. The desired performance characteristics for this IRSIR are: high optical throughput, a small physical package, and 0.5 to 1.0 percent spectral resolution over the 0.2 to 12 um range at frame rates of 30-100 frames p ...

The present system of communication between KC-135/KC-10 tanker aircraft and receptacle-equipped receiver aircraft calls for communication based on aircraft lights. The Air Force requires a system for undetectable verbal communication between tanker and receiver from a range of 1500 meters to point blank. This document describes an approach for providing undetectable verbal tanker/receiver communi ...

This program will demonstrate the applicability of the freeze crystallization (FC) process dirctly to U.S. Air Force environmental managers by, in phase I, (1) finding applications that are well served by this technology, (2) demonstrating the capabilities of the FC process by processing wastes in FTCAC's lab pilot plant facilities, and (3) developing a design for a prototype FC plant that will be ...

When loading nitrogen tetroxide before launching the space shuttle, fugitive N2O4 is absorbed into caustic solutions in a two stage scrubber solution. The second stage of the scrubber has sodium sulfite added to the alkaline scrubbing solution to act as an oxidant scavenger, to improve scrubbing efficiency. The N2O4 oxidant reacts with water and with the sulfite to form acids (neutralized by the a ...

To provide the Air Force with the capability of measuring optical wave-front properties around aerodynamic structures in wind tunnels, Innovation Associates proposes to develop a High-Speed, Aero-Optical Wave-frong Characterization System (AWCS) which is capable of recording 64,000 or higher wave-front phase measurements per second. AWCS will consist of three subsystems: (a) an innovative high spe ...
