Abstract:
A conformable tank includes a body with a plurality of composite walls formed around a cavity, and an internal support connected to one of the plurality of composite walls and positioned in the cavity. The plurality of composite walls includes a flat side wall disposed opposite a curved side wall. A first section of one of the plurality of composite walls includes an exterior facing, an interior facing, and a core positioned between the exterior facing and the interior facing.
Abstract:
A heating element is provided with a conductive path pattern which can be printed in a mask-free manner (e.g., drop-on-demand) with existing printing technology. The printing step can be performed, for example, with a thermal inkjet printer, a piezoelectric inkjet printer, an aerosol jet printer, or an ultrasound printer. The ink solution can be formulated so that it establishes an electrically conductive path which is free of polymer binders.
Abstract:
A pneumatic deicer includes a base layer, a forming layer, a first chamber, and a first sensor. The base layer has an inlet, a first side, and a second side. The forming layer is connected to the base layer along at least two seams and has inner side and an outer side with the outer side being distant from the base layer. The first chamber is formed between the base layer and the forming layer and configured to be inflated by air passing into the first chamber through the inlet in the base layer. The first sensor is situated within the first chamber.
