A panel assembly (such as for an internal cabin of an aircraft) includes at least one liquid flow path formed on at least one surface through surface treatment. The at least one liquid flow path is formed in relation to at least one bank on the at least one surface. The at least one liquid flow path is configured to divert liquid to a desired location.

A method includes providing a structure having a surface, treating a portion of the surface to modify a wettability of the portion of the structure, and forming at least one liquid flow path on the surface through said treating.

A moisture management system for use in an aircraft incorporates a bladder supported between adjacent structural members between a skin and a sidewall panel. The bladder is configured to passively expand to contact at least one of the structural members as a pressure decreases during an ascent of the aircraft and to collapse as the pressure increases during a descent of the aircraft.

A moisture control assembly for use with a support beam extending through an insulation layer is provided. The insulation layer is positioned between an outer wall and an inner wall. The assembly includes: a moisture path close-out structure coupled to the insulation layer at an aperture defined through the insulation layer, the moisture path close-out structure including an opening substantially aligned with the aperture and configured to receive the support beam therethrough; and a coupling mechanism configured to secure the moisture path close-out structure to the support beam such that the moisture path close-out structure is partially pulled away from the insulation layer, the coupling mechanism and the moisture path close-out structure configured to direct liquid flow down and away from the support beam and along the insulation layer.

An insulation system comprises a first insulation blanket and a second insulation blanket. The first insulation blanket extends circumferentially within a curved body. The second insulation blanket extends circumferentially within the curved body and covers a zero position of the curved body. A portion of the second insulation blanket covers a portion of the first insulation blanket so that the portion of the second insulation blanket is between the portion of the first insulation blanket and the curved body to form an overlap. The overlap is positioned within a range having an absolute value of 5 to 40 degrees from the zero position of the curved body.

An internal cladding part for cladding a fuselage structure of an aircraft is disclosed having a first cover layer that extends in a planar manner, a second cover layer that extends in a planar manner, a core layer which is disposed between the first and the second cover layer and is connected to the first and the second cover layer and defines a receptacle cavity, and an insulation structure having a porous insulation core and an evacuated film sheath that encases the insulation core in a gas-tight manner. The insulation structure is disposed in the receptacle cavity between the first and the second cover layer.

Devices and methods to capture moisture at a structural member in a vehicle. The devices include a flexible tray that can snap-fit onto an exterior of the structural member. Once attached, the flexible tray can collect moisture from the structural member. A diverter is coupled to the flexible tray. The diverter diverts the collected moisture away from the structural member.

A moisture control system includes an anode coupled to an insulation blanket that is positioned between an inner wall and an outer wall of an aircraft fuselage, a cathode coupled to an interior surface of the outer wall, and a power control unit coupled to the anode and the cathode to apply voltage across the anode and the cathode. When the voltage is applied across the anode and the cathode, moisture is drawn away from the anode and toward the cathode on the interior surface of the outer wall and guided along a drainage path provided via structural members disposed between the inner wall and the outer wall toward a drainage port.

An air drying system including a compressor coupled to a first air inlet through which moist air is received, a first turbine in fluid communication with the compressor and coupled to a first air outlet through which dry air is expelled, and a second turbine coupled to a second air inlet and a second air outlet and being driven, at least in part, by an air flow caused by a pressure differential between the second air inlet and the second air outlet, where the second turbine is operably coupled to the compressor and the first turbine by a drive mechanism so that rotation of the second turbine drives rotation of the compressor and the first turbine.

A moisture control apparatus for use with a structure within an aircraft fuselage, the structure including an upper surface, the apparatus comprising: a moisture absorbing layer including a moisture absorbing material, the layer including a leading edge, a trailing edge, side edges, an upper surface, and, a lower surface; and, a wicking layer disposed in fluid communication with the lower surface of the moisture absorbing layer, the wicking layer including a wicking layer leading edge, a wicking layer trailing edge and a wicking layer upper surface configured for capillary action of moisture from the wicking layer trailing edge towards the wicking layer leading edge, wherein the wicking layer leading edge is offset from the leading edge of the moisture absorbing layer such that an offset portion of the wicking layer is exposed to air to facilitate evaporation of the moisture.
