  • Water supply system for an aircraft
    Patent number: 12105541
    Abstract: A water supply system for an aircraft having consumers with buffer stores connected to a water tank by lines and a pressure source. Each consumer has a filling valve between the buffer store and the pressure source. The buffer store can be filled by opening the filling valve. In each consumer, water can be removed from the buffer store by opening a consumer valve. Each consumer transmits at least one state parameter describing a state of the buffer store of the respective consumer to a control system. The control system controls opening and closing of the filling valves of the consumers taking into account the transmitted state parameters such that removal of water from the water tank by the pressure source does not exceed a threshold value at any point in time. An aircraft having a water supply system and method for controlling a water supply system are disclosed.
