Abstract: A fuel boost pump assembly for an aircraft includes a first inlet for receiving a first pressurized fuel flow, a second inlet, an assembly outlet, a pump for transferring fuel between the second inlet and the assembly outlet, and a hydraulic motor adapted to drive the pump. The hydraulic motor is fluidly connected between the first inlet and the assembly outlet, and is mechanically coupled to the pump. Further, in use, the hydraulic motor converts hydraulic energy of the first pressurized fuel flow into driving energy of the pump such that the pump generates a second pressurized fuel flow between the second inlet and the assembly outlet.

Abstract: One or more boost pumps for a liquid hydrogen fuel system are disposed within the fuel tank and fully flooded. An electrical connector of each boost pump is sealed from the fuel tank and accessible from an exterior of the fuel tank while the boost pump is installed. Each boost pump can be independently replaced using a toolbox. Each boost pump is purged of fuel before being replaced by introducing a gas at a center region of the boost pump. The toolbox and new boost pump are purged prior to removal of the old boost pump. Each boost pump can be formed from modular components.

Abstract: The present disclosure relates generally to a system for removing fuel from a mixture of air and fuel vapor in an ullage space of an aircraft fuel tank. The system includes a compressor for drawing the mixture of air and fuel vapor from the ullage space and directing the mixture of air and fuel vapor through a heat exchanger where the mixture of air and fuel vapor is cooled. The system also includes a turbine configured to be driven by the mixture of air and fuel from the heat exchanger. Power from the turbine can be transferred back toward the compressor to assist in driving rotation of the compressor. The system further includes a separator for receiving the mixture of air and fuel vapor from the turbine and separating at least some liquid fuel from the mixture of air and fuel vapor. From the separator, a separated liquid fuel and a mixture of air and fuel vapor with reduced concentration of fuel vapor are returned to the aircraft fuel tank.

Abstract: An aircraft fuel tank inerting system includes an inlet, an oxygen absorption unit, and a vent to discharge oxygen from the system. The inlet may be configured to be in fluid communication with a ullage of a fuel tank. In embodiments, the oxygen absorption unit is in communication with the inlet and includes a chamber, a temperature reversible oxygen absorption medium within said chamber, and a temperature controller for selectively heating or cooling the medium. The reversible oxygen absorption medium may be a medium which absorbs oxygen by chemisorption.

Abstract: A hydrogen fuel system for an aircraft is configured to provide hydrogen fuel to the engines for propulsion. The fuel system also may provide hydrogen fuel to a fuel cell arrangement to generate electricity for use on the aircraft. The fuel cell arrangement may be selectively coupled to the feed lines for the engines. A ventilation system regulates the pressure within the one or more fuel tanks and the feed lines. The ventilation system can vent hydrogen vapor to atmosphere or can transfer hydrogen vapor between the fuel tanks and the fuel cell arrangement. A jet pump and accumulator may pull vapor from the feed lines as needed.

Abstract: A fluid conduit includes, a body, a first conduit portion connected to the body, a second conduit portion connected to the body, and a base connected to the second conduit portion. The body, the first conduit portion, the second conduit portion, and the base may be formed as a monolithic component via additive manufacturing. A method of making a fluid conduit may include forming sets of layers. The set of layers may include parts or portions of the fluid conduit and/or supports.
