Abstract: A process for coating a metallic surface of an aircraft. The process includes applying to the metallic surface a composition that polymerizes to form a polyurea having a tensile strength of more than 3500 psi and at least 700% elongation. The polyurea can be formed from an A-side and a B-side, where the weight percents of components for the A-side are: from about 30 to about 65 percent of polyisocyanate; from about 15 to about 70 percent of a polytetramethylene ether glycol; diluent, from 0 to about 20 percent; where the weight percents of components for the B-side are: from 35 to about 40 percent of one or more aromatic diamines; from about 20 to about 70 percent of one or more amine terminated polyether polyols.

Abstract: A shipping container interrogation apparatus and method that utilizes the tubular frame members of the container to deliver input air to the interior of the container, and to receive sample air from the interior of the container. A detection apparatus may be used to detect an unauthorized material in the sample air that is received from the interior of the container. Sample air from the detection apparatus may be recycled back into the container by use of a tubular frame member of the container. Input air may be delivered to the interior of the container with turbulence and in any desired direction or pattern for better interrogation of the interior of the container.

Abstract: A polysilazane composition, formulated from a vinyl silazane and an organometallic accelerator, and associated methods thereof.

Abstract: Extraction devices are disclosed for extracting liquid particulates from a gaseous stream. The extraction devices may have a powered or free spinning rotating extractor that may be mounted in the extraction device's source or extraction duct. During operation, liquid particulates impinging on the rotating extractor form a thin film of extracted liquid that travels due to centrifugal force to the periphery of the extractor's exterior surface where the extracted liquid may be flung to the inner surface of the extraction duct and collected.
