Abstract: A water supply system for an aircraft and a method for draining water from or passing air into or out of a buffer tank of a water supply system in an aircraft. The system includes a water buffer tank having a fluid inlet and outlet, a supply arrangement for selective flow from the fluid outlet to a user equipment, and a relief arrangement for permitting fluid flow from the fluid outlet. The relief arrangement includes a relief conduit having a separation element with a separation element inlet positioned above a separation element outlet and separated therefrom by a separation distance such that water flowing in a forwards direction therethrough flows from the inlet to the outlet across the separation distance, and water flowing in a reverse direction therethrough flows into the separation element outlet and is retained therein, and wherein the separation element is defined by the user equipment.

Abstract: A method for draining a local water distribution system including a buffer, supply lines connecting one or more consumers to the buffer and consumer valves associated with the one or more consumers. The buffer is configured for locally storing water from an aircraft water supply system to be distributed to the one or more consumers. Water from the buffer can be dispensed through a consumer of the one or more consumers by opening the consumer valve associated with the respective consumer. Water is drained from the supply lines by opening the consumer valves. Water is drained from the buffer through one of the supply lines and the consumer valves or through a drain valve connecting the buffer to a wastewater system of an aircraft. A corresponding local water distribution system and an aircraft are disclosed.

Abstract: A drain mast for an aircraft for discharge of water from the aircraft interior with a line which extends in a line direction from a connector end to a discharge end. The connector end can connect to another line in the interior of the aircraft, through which further line water flows into the drain mast. The discharge end can discharge water into a surrounding area of the aircraft. The line includes a plastic, into which a conductive material is embedded, by which the line can be heated electrically, by a heating current being conducted through the conductive material. A proportion of the embedded conductive material in the line increases in the line direction per length unit from the connector end of the line towards the discharge end such that the heating power which is introduced into the line per length unit increases from the connector end towards the discharge end.

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.

Abstract: A method for draining a water supply system onboard an aircraft which supplies water from a central water tank to consumers. Water is supplied by a supply pump from the central water tank through supply lines of a conduit system to consumers. Each consumer is associated with a supply valve for drawing water from the conduit system. The supply lines have a maximum internal diameter of 8 mm or less. The method includes closing the supply valves of all consumers, subjecting the supply lines of the conduit system at the at the supply pump to a draining pressure and sequentially opening the supply valves of all consumers for removing water from the supply lines of the conduit system. A corresponding water supply system and an aircraft are disclosed.

Abstract: A method for operating an on-board water supply and distribution system of an aircraft for supplying water includes a central tank, consumer assemblies with a supply device and a buffer tank, pump operable in a supply mode and reverse mode, filter device, and high-pressure conduit system. The central tank connects to the pump's upstream side. The conduit system connects the downstream side and consumer assemblies. The pump in supply mode delivers water from the downstream side to the buffer tank. In reverse mode, the pump can convey water from the downstream side to the upstream side. The method includes operating the pump in supply mode so water from the central tank goes to a consumer assembly in a first time interval to fill the buffer tank, and operating the pump in reverse mode in a second time interval so water from the buffer tank passes through the filter device.

Abstract: A method for operating an on-board water supply and distribution system of an aircraft for supplying water includes a central water tank, first consumer assemblies with buffer tanks each including a heater to heat up water in the buffer tank to a disinfection temperature, pump having upstream and downstream sides to operate in supply and reverse modes, and high-pressure conduit system. The central water tank connects to the pump's upstream side. The conduit system connects the downstream side with a first consumer assembly. The method includes operating the pump in supply mode where water from the central tank goes to a first consumer assembly to fill a buffer tank, operating a buffer tank heater so water heats to a predetermined disinfection temperature, and operating the pump in reverse mode so heated water passes through a part of the conduit system and the upstream side of the pump.

Abstract: An aircraft with a drinking water supply and distribution system including a water storage tank, a consumer equipment, a pressurizer, a pressure reducer and a conduit system connecting the drinking water storage tank to the consumer equipment via the pressurizer and supplying water from the at least one water storage tank to the at least one consumer equipment. The pressurizer pressurizes water in the conduit system with a peak pressure exceeding a supply water pressure threshold. The conduit system includes flexible conduits having a maximum internal diameter of less than 8 mm. The pressure reducer is provided for reducing the pressure of water supplied to the consumer equipment below a consumer water pressure threshold. The supply water pressure threshold exceeds the consumer water pressure threshold.
