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: A solenoid for a bleed valve includes a solenoid body with an actuation fluid passage, a bleed valve passage, and a drive fluid chamber. A main armature is disposed within the solenoid body and is movable between open and closed positions, the actuation fluid passage being in fluid communication with the control outlet in the open position, the actuation fluid passage being fluidly isolated from the bleed valve passage in the second position. A pilot armature is disposed within the solenoid body, is movable relative to the main armature, and is operably coupled to the main armature by the drive fluid chamber to move the main armature between the open and closed positions by controlling issue of a drive fluid into and out of the drive fluid chamber.

Abstract: A shut-off valve system includes a tank having an inlet and an outlet with a flow path defined therebetween. A float within the tank occludes the tank outlet at a first fluid level under positive G forces and unoccludes the tank outlet at a second fluid level under positive G forces. A flow restricting orifice and/or a hydraulic fuse is downstream of float and tank outlet to restrict fluid communication between tank outlet and an ejector pump. A method for restricting flow in an ecology fuel return system includes recovering fuel from engine components, communicating the fuel to an inlet of a fuel tank, pumping the fuel from an outlet of fuel tank to an inlet of an engine when a float within tank unoccludes the outlet of the fuel tank, and restricting fluid flow from tank outlet to an ejector pump with a flow restricting orifice and/or a hydraulic fuse.
