Abstract:
A humidity control system including a heat pump with desiccant coated passive heat transfer devices on both sides of the heat pump and an air circulation system for alternately directing a process air stream to be humidity controlled and a separate regenerative air stream past each side. As desiccant on one side becomes laden with moisture, the air streams are redirected to the opposite sides of the heat pump so the regenerative stream can remove moisture from the first side. Simultaneously, the air stream to be humidity controlled uses the previously regenerated desiccant on the second side.
Abstract:
An exemplary elongated elevator load bearing member includes a plurality of tension elements that extend along a length of the load bearing member. A plurality of weave fibers transverse to the tension elements are woven with the tension elements such that the weave fibers maintain a desired spacing and alignment of the tension elements relative to each other. The weave fibers at least partially cover the tension elements. The weave fibers are exposed and establish an exterior, traction surface of the load bearing member.

Abstract:
A system for the management of thermal transfer in a gas turbine engine includes a heat generating sub-system in operable communication with the engine, a fuel source to supply a fuel, a fuel stabilization unit to receive the fuel from the fuel source and to provide the fuel to the engine, and a heat exchanger in thermal communication with the fuel to transfer heat from the heat generating sub-system to the fuel. A method of managing thermal transfer in an aircraft includes removing oxygen from a stream of a fuel fed to an engine used to drive the aircraft, transferring heat from a heat generating sub-system of the aircraft to the fuel, and combusting the fuel. A system for the thermal management of an aircraft provides for powering the aircraft, supplying a fuel deoxygenating the fuel, and transferring heat between a heat generating sub-system of the aircraft and the fuel.
