Abstract: A sandwich panel includes a honeycomb core of a plurality of cells. A first skin is adhered to a first surface of the honeycomb core with an adhesive. A second skin is adhered to a second surface of the honeycomb core with the adhesive. The plurality of cells extend longitudinally between the first and second skins. The first and second skins adhere to the honeycomb core to form a sandwich panel having a surface area of at least 2.25 square feet. A foam fill is disposed within the cells of the honeycomb core. The foam fill and the honeycomb core define a first gap region proximate to the first skin and a second gap region proximate to the second skin.

Abstract: A pressure regulated structure includes a first layer, a second layer, a non-metallic honeycomb assembly, and a vent. The honeycomb assembly is between the first layer and the second layer and includes a plurality of walls forming cells, at least some of the walls including laser-formed apertures to allow fluid communication between cells. The vent is fluidly coupled to the honeycomb assembly, wherein fluid in the cells of the honeycomb assembly may be removed through the vent to decrease pressure in the structure.

Abstract: A drying tool for drying moisture present in cells of a honeycomb core. The tool includes an inflatable bladder compartment having a bendable exterior surface and a plurality of open-ended nozzles protruding from this exterior surface, with each nozzle having a passage in fluid communication with the bladder compartment. A connector element is connectible with a hot air source for delivering hot air into the bladder compartment for subsequent dispatch through the plurality of nozzles. Preferably, the nozzles are situated in a grid formation and are of a generally conical configuration. In use, the bendable exterior surface with the protruding nozzles is bowed or curved to generally configure to the exterior shape of the honeycomb core such that hot air is pinpointed in a grid pattern to drive heated air into the core and thereby cause circulation through the core cells for moisture evaporation.

Abstract: A pressure application device for applying pressure to a repair patch of a variable contoured aircraft surface, the pressure applicator device is provided with an inflatable pressure bladder. The bladder is configured for applying pressure to the repair patch and is formed of a generally fluid tight elastic material. The pressure applicator device is further provided with at least one variable direction adjustable arm. The arm is disposed in mechanical communication with the bladder for facilitating the application of pressure by the bladder to the repair path upon inflation of the bladder. The bladder is further provided with at least one suction device for providing suction attachment to the aircraft surface. The bladder is attachable to a respective one of the at least one variable direction adjustable arm. The arm facilitates selective attachment of the respective suction device to the variable contoured aircraft surface while maintaining the position of the bladder with respect to the repair path.

Abstract: The present invention is a hand held tool for removing coatings from a substrate. The hand held tool includes a housing having a front section with an outlet, a mid section with an inlet, and a rear section, a heat source disposed within the front section of the housing for emitting heat through the outlet, and a vacuum source disposed within the mid section of the housing for providing suction through the inlet. The hand held coating remover further includes a power source disposed within the rear section for supplying power to the heat source and the vacuum source, a control panel having a heat controller for adjusting and controlling the heat emitted from the heat source through the outlet and a vacuum controller for adjusting and controlling the suction provided by the vacuum through the inlet, and a blade located adjacent to the inlet and resiliently coupled to the housing.
