Abstract: An inflatable mast couplable to an underwater vehicle includes a flexible material defining an interior volume, a head structure, and a spring coupled to at least one of the flexible material and the head structure. The flexible material is designed to be filled with air to form an inflated mast structure that extends away from the underwater vehicle. The head structure is disposed at a distal end of the inflated mast structure and in some cases has a rigid shape that forms a panel having an outer surface that is flush with an outer surface of the underwater vehicle, when the mast structure is deflated and stowed. The spring is designed to provide a tensile force on at least one of the flexible material and the head structure when the flexible material is inflated to form the mast structure. A system includes the inflatable mast and a pump.

Abstract: A rollable mast system couplable to an undersea vehicle includes a mast made of a bi-stable composite material configured to roll onto itself in a first state and to stiffen into an elongated stable shape in a second state, and a head structure coupled to a distal end of the mast. The rollable mast system further includes a spool configured to support at least a portion of the bi-stable composite material in its first state and a roller in contact with the bi-stable composite material and configured to pay out the bi-stable composite material from the spool in a direction away from a hull of the undersea vehicle. The bi-stable composite material is in the first state as it passes from the spool to the roller, and the bi-stable composite material is in the second state after it passes the roller.

Abstract: A transducer system includes a housing having an opening, an electromechanical transducer within the housing, and an elastomeric boot over the opening. At least a portion of the elastomeric boot includes copper-comprising particles. In some applications, the copper acts as an antifouling agent and/or enhances the thermal conductivity of the elastomeric boot.
