An effective process for recycling plastics and composites used in aircraft does not currently exist. As a result, scrap and used materials are disposed of in landfills. A chemical recycling process is proposed that will allow the components of these waste materials to be converted to valuable hydrocarbons, fillers and fibers that can then be reused or sold. The proposed chemical recycling process ...

A novel tertiary recycling process is proposed for investigation as an economical means for reclaiming scrap aircraft transparency materials. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at temperatures below 200 C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Met ...

Functionally smart materials, which have to ability to perform both sensing and actuating operations, are being developed to perform many aircraft type of control events. Smart materials, fabricated suing "continuous ferroelectric fibers," are being consider for full flight control of subsonic missiles, as the servoactuator system, specifically, and for active aerodynamic surface cont ...

The proposed research combines an innovative eigenvector method with other electromagnetic techniques to produce a hybrid approach towards solving the EM coupling to satellite cavity problem. The physical structure is divided into an exterior region and one or more interior regions. The exterior region is modeled with method of moments (MOM) and or hybrids of MOM with the uniform theory of diffr ...

STANDARD TOADS CRYSTALS DO NOT PERFORM CONSISTENTLY AT LOW OVERPRESSURES DUE IN PART TO LOW SIGNAL OUTPUT OF THE PZT CRYSTAL AND ALSO DUE TO ELECTRICAL CROSSTALK. WE PROPOSE TO INVESTIGATE TWO TOA TRANSDUCER TYPES THAT ARE PROVEN CONCEPTS IN OTHER APPLICATIONS. WE WILL DESIGN TECHNICIAN FRIENDLY INTERFACES FOR THESE MEASUREMENT SYSTEMS. THE PHASE I DESIGN WILL INTERFACE WITH STANDARD TOADS III REC ...

A METHOD FOR THE EVALUATION AND OPTIMIZATION OF EXPLOSIVE MATERIAL CHARACTERIZATION IS PROPOSED. DAMAGE OF A RIGID RUNWAY CONCRETE SLAB WILL BE OPTIMIZED FOR VARIOUS EXPLOSIVE ENERGY RELEASE RATES. THE STEPS FOR THE PROGRAM ARE: 1) COLLECTION AND EVALUATION OF RUNWAY TEST DAMAGE RESULTS, 2) PRELIMINARY LITERATURE SEARCH FOR APPROPRIATE HYPERGOLIC ENERGY RELEASE RATE, 3) NUMERICAL SIMULATION OF EXP ...

This proposal discusses the development of a Graphical Vulnerability Assessment (GVA) system for setting up, executing, and visualizing the results of vulnerability assessments. The vulnerability assessments might be for hardened concrete targets, mobile ground targets, or mobile air targets. This graphical tool will allow users to link together modules from various vulnerability analyses by using ...
