An aircraft cabin portion having a cabin device module which has an upper face, a fluid-guiding element located on the upper face of the cabin device module, and a fluid collector located at a lower end of the fluid-guiding element. The fluid collector may consist substantially of a flexible material which forms a lumen for draining a fluid, wherein the lumen has an entry opening located at the lower end of the fluid-guiding element so that the fluid flows from the at least one fluid-guiding element into the lumen. Also an aircraft having such an aircraft cabin portion.

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.

Devices and methods to control moisture at a support member in a vehicle. The devices are configured to be attached to the support member and include a moisture absorbing portion and an evaporative portion. Methods of assembling the support member in the vehicle include prefabricating the device and preassembling the device onto the support member prior to the support member being installed in the vehicle.

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.

Embodiments of the present invention provide a water management system for use on board a passenger transport vehicle. The water management system may be used to address and manage excess humidity, water leaks, or any other instance when water or other liquid may collect at a certain location. The disclosure provides a system for managing excess water and for optionally delivering the water to another location. The removal location may be a disposal outlet or it may be a beneficial use of the collected water on-board the vehicle.

A moisture wicking heat shrink sleeve for aircraft cabin moisture control incorporates a heat shrinkable tube of predetermined length receivable over a structural member. A moisture absorbing layer is adhered to a surface of the heat shrinkable tube with the heat shrinkable tube and adhered moisture absorbing layer configured for radial contraction from a first expanded condition to a second contracted condition upon application of heat.

Systems and methods are provided for insulation and moisture drainage. One exemplary embodiment is an apparatus comprising a bay blanket configured to insulate an aircraft. The bay blanket includes insulation, and a first waterproof lip that protrudes from the insulation in an outboard direction towards a frame of the aircraft and extends along a length of a leftward side of the bay blanket. The bay blanket also includes a second waterproof lip that protrudes from the insulation in an outboard direction towards the frame of the aircraft along a length of a rightward side of the bay blanket.

Systems and methods are provided for enhanced water capture systems for aircraft interiors. One embodiment is a strip that is formed from a water-absorbent material for retaining moisture. The strip is adhered to an interior surface of an aircraft at a location proximate to an entry point for water into a cabin of the aircraft, and the strip comprises holes within the water-absorbent material that are staggered with respect to each other.

A honeycomb thermal insulation structure may comprise a first facesheet, a second facesheet, and a honeycomb core between the first facesheet and the second facesheet. The honeycomb core may include a plurality of honeycomb unit cells each composed of walls having a height and spaced by a distance. The walls of the honeycomb cells may have perforations. The honeycomb thermal insulation structure may further comprise a non-convective gas loaded in the honeycomb unit cells between the walls. A flow of the gas through the perforations may be substantially absent.

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.
