Abstract: An engine fuel system is disclosed for managing drainage of fuel in response to an engine shut-down condition. For normal operation, a piston of a piston assembly is maintained in a first position by pressurized fuel in a volume on a first side of the piston. In response to engine shut-down, pressure is removed from the first side of the piston and fuel in the volume on the first side of the piston is drained into a return conduit that is part of the fuel system's thermal management system. Displacement of the piston in response to removal of pressure on the first side of the piston creates a volume on a second side of the piston for drainage of fuel from a fuel manifold.

Abstract: A heat exchanger is disclosed including an array of interlaced conduits. The conduit array includes a first plurality of conduits connected to a first inlet header at one end of the first plurality of conduits and to a first outlet header at an opposite end of the first plurality of conduits. This first plurality of conduits provides a first fluid flow path from the first inlet header through the first plurality of conduits to the first outlet header. The conduit array also includes a second plurality of conduits crossing and interlaced with the first plurality of conduits. First and second fluid flow paths are provided through the first and second pluralities of conduits, and a third fluid flow path is through open spaces between the crossed interlaced first and second pluralities of conduits.

Abstract: A compact heat exchanger is provided and includes a first manifold defining an inlet for receiving from a component a fluid to be cooled and an outlet for returning the cooled fluid to the component to cool the component. A second manifold is disposed spaced from the first manifold. A core extends between and fluidly communicates with the manifolds and includes hexagonal channels. Each channel is formed by mini-tubes defining respective triangular passages. A cross-section of the core defines an irregular-cross structure. The fluid enters the inlet of the first manifold, makes a first pass through the mini-tubes to the second manifold, makes a second pass through the mini-tubes to the first manifold such that the fluid is cooled across the mini-tubes, exits the first manifold through the outlet, and returns to the component to cool the component. A method of manufacturing the heat exchanger is provided also.

Abstract: An electrical chassis for use in high temperature environments is disclosed. The electrical chassis may be employed, for example, in close proximity to the combustion chamber of a jet engine. The electrical chassis is constructed with a substrate formed from a material with low thermal conductivity and low electrical conductivity, such as polyetheretherketone. A reflective surface may be disposed on a housing containing the substrate to reduce the absorption of radiation. A heat sink and fluid inlet and outlet may also be arranged to remove heat generated by the electrical components.
