Abstract
A high pressure water supply system for an aircraft includes a main water supply tank, water consumers, pressurization units configured to convey water from the main water supply tank to the water consumers, and a controller. One pressurization unit of the pressurization units conveys water to a first subset of water consumers of the water consumers via a corresponding high pressure water supply line, and the controller is configured to control an output pressure of the one pressurization unit depending on a hydraulic resistance length of the high pressure water supply line.
Claims15
A high pressure water supply system for an aircraft, the water supply system comprising:
- a main water supply tank;
- a plurality of water consumers;
- a plurality of pressurization units that are each connected to the main water supply tank in parallel and each of which is configured to convey water from the main water supply tank to one or more of the plurality of water consumers via a high pressure water supply line that is supplied with water by a corresponding one of the plurality of pressurization units;
- and a controller;
- wherein one pressurization unit of the plurality of pressurization units is configured to convey water to a first subset of water consumers of the plurality of water consumers;
- wherein the controller is configured to control an output pressure of the one pressurization unit depending on a hydraulic resistance of the high pressure water supply line that is supplied with water by the one pressurization unit;
- wherein a further pressurization unit is configured to convey water to the first subset of water consumers via the high pressure water supply line that is fluidly connected to the first subset of water consumers;
- the further pressurization unit is fluidly connected to the one pressurization unit in parallel;
- and the controller is configured to control the one pressurization unit and the further pressurization unit on a required flow rate of water at the first subset of water consumers.
