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 ...

Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

A novel tertiary recycling process is proposed for investigation as an economical means for recycling shipboard plastic waste. 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. Metal, glass, and fil ...

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 ...

Future battlefields will require independent operations and increased operational tempo, placing severe burdens on weapons platform crewmembers in the areas of information flow management, data fusion, and assessment of data to arrive at the most tactically acceptable decisions. Work continues in the development of decision aids to assist direct/indirect fire weapon platform commanders in accompl ...

The field training of Reserve Component units is difficult because of limited training time and facilities and the difficulty in assembling all necessary player personnel. Computer wargames which allow interactive play of player personnel are a relatively inexpensive alternative and supplement to field exercises. Unfortunately, most existing simulations are designed to exercise maneuver command an ...

A METHOD FOR DETECTING BURIED PLASTIC MINE IN PRESENTED WHICH EMPLOYS THE ACTIVATION OF NITROGEN BY 14 MEV NEUTRONS AND THE SUBSEQUENT DETECTION OF EMITTED 7 MEV GAMMA RAYS. THE DETECTION SYSTEM IS TRANSPORTED BY A REMOTELY PILOTED VEHICLE WHICH PROVIDES THE REQUIRED STANDOFF DISTANCES.
