Abstract: A system for cooling individual integrated actuator packages (IAPs) positioned throughout the aircraft in a power-by-wire actuation system is disclosed. A low-pressure hydraulic fluid circulates throughout the aircraft to control the temperature of the individual IAPs and to maintain and replenish the hydraulic fluid within the individual IAPs. A thermo-control loop containing low-pressure hydraulic fluid includes a pump, low-pressure hydraulic lines, a heat exchanger, a reservoir and a filter. The entire system provides heat transfer for a high- or low-temperature environment, as may be present on an aircraft. The individual IAPs may be coupled together in series or, alternatively, in parallel, depending upon the design constraints of the system. Compared with distributed hydraulic systems, energy consumption, weight, and cost are significantly reduced by using a low hydraulic pressure for the circulating fluid. Survivability is significantly increased over that provided by a distributed hydraulic system.

Abstract: Thermal energy radiation is converted into another energy form by setting up a temperature differential between two heat sinks forming part of a conventional converter or heat engine, but the warmer heat sink derives its input energy by collecting optically-focused thermal radiation from a primary heat sink within the converter structure. Heat rejected by the cooler heat sink is recycled to the primary heat sink to enhance the thermal efficiency above the Carnot level set by the base temperature conditions. The power rating of the converter is enchanced by combination with a reverse heat engine which elevates the temperature of heat input to the primary heat sink and so the temperature of the radiating surface.
