Apparatus for obtaining water onboard an aircraft

turbojet engine designed to generate water on board an aircraft using one or more cabins fuel; where the turbojet engine comprising: a turbine (33, 34) a separation means (7) a production unit of water as one or more cabins high temperature fuel (1); where there is provided a partial or full integration of the production unit of water in the turbojet engine so that the combustion chamber of the turbojet engine are replaced wholly or partially by booths high temperature fuel (1) and thus full or completely replaces the process that develops in the combustion chambers of traditional type; where a cabin of high temperature fuel (1) for complete or partial replacement of a combustion chamber is constructed so that the air flowing through the power unit of the aircraft can be driven into the cabin high temperature fuel (1) it can be heated by an oxidation process in the fuel cell of high temperature (1) and where the energy stored in the heated air can then become the turbine (33, 34) into rotational energy, and where the fuel cell high temperature (1) is a downstream separation means (7) which is condensed water of the exhaust cabin high temperature fuel (1).
