A liquid delivery system is configured to pump a liquid (e.g., a cryogenic liquid) without a mechanical pump. The system includes a storage tank to store the liquid at low pressure; a transition tank configured to transition the low pressure liquid to a high pressure gas; and a pumping tank configured to first receive part of the low pressure liquid from the source tank and then to receive the pressurized gas from the transition tank to expel the low pressure liquid from the pumping tank. The liquid delivery system can be used to deliver fuel to an engine (e.g., on an aircraft).

Liquid delivery system

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.
