Abstract
A centrifugal reservoir pump for processing a hydrogen stream in an aircraft. In particular, a centrifugal reservoir pump including a pump casing, a hydrogen stream inlet, a rotor being rotatably arranged in the interior part of the pump and including rotor vanes for accelerating the hydrogen stream, and two hydrogen stream outlets. Further provided is a tank unit including the centrifugal reservoir pump and a reservoir for hydrogen. Further provided is an aircraft including a centrifugal reservoir pump or a tank unit. Further provided is a method of processing hydrogen in an aircraft.
Claims12
A centrifugal reservoir pump, used for processing a hydrogen stream in an aircraft, comprising:
- a pump casing encompassing an interior part of the pump;
- a hydrogen stream inlet;
- a rotor being rotatably arranged in the interior part of the pump and comprising rotor vanes for accelerating the hydrogen stream perpendicular to a rotating axis of the rotor and for accelerating the hydrogen stream in a circumferential direction;
- and
- a first hydrogen stream outlet and a second hydrogen stream outlet,
- wherein the pump casing comprises a pump housing and a cage, wherein the cage is rotatably arranged, and,
- wherein the cage, being rotatably arranged, comprises through-holes for passing liquid hydrogen into a gap between the pump housing and the cage enabling a hydrostatic bearing.
An aircraft comprising:
- a pump comprising:
- a pump casing encompassing an interior part of the pump;
- a hydrogen stream inlet;
- a rotor being rotatably arranged in the interior part of the pump and comprising rotor vanes for accelerating the hydrogen stream perpendicular to a rotating axis of the rotor and for accelerating the hydrogen stream in a circumferential direction;
- and
- a first hydrogen stream outlet and a second hydrogen stream outlet,
- wherein the pump casing comprises a pump housing and a cage, wherein the cage is rotatably arranged, and,
- wherein the cage, being rotatably arranged, comprises through-holes for passing liquid hydrogen into a gap between the pump housing and the cage enabling a hydrostatic bearing.
An aircraft comprising:
- a tank unit comprising:
- a reservoir for hydrogen;
- and,
- a pump comprising:
- a pump casing encompassing an interior part of the pump;
- a hydrogen stream inlet;
- a rotor being rotatably arranged in the interior part of the pump and comprising rotor vanes for accelerating the hydrogen stream perpendicular to a rotating axis of the rotor and for accelerating the hydrogen stream in a circumferential direction;
- and
- a first hydrogen stream outlet and a second hydrogen stream outlet,
- wherein the pump casing comprises a pump housing and a cage, wherein the cage is rotatably arranged, and,
- wherein the cage, being rotatably arranged, comprises through-holes for passing liquid hydrogen into a gap between the pump housing and the cage enabling a hydrostatic bearing.
