Abstract
A cryogenic tank for storing cryogenic fluids is disclosed. The cryogenic tank is typically configured to be mounted on a vehicle for supplying cryogenic fuel to a propulsion system of the vehicle. The cryogenic tank comprises an inner vessel for containing cryogenic fluids and an outer vessel surrounding the inner vessel to define a vacuum insulating volume therebetween. The outer vessel is configured to transmit static and/or dynamic loads, while the inner vessel is partially or completely isolated from such loads.
Claims20
An aircraft, comprising:
- an airframe configured to transmit aircraft flight loads,
- a propulsion system, and
- a cryogenic tank supplying the propulsion system, the cryogenic tank comprising
- an inner vessel defining a closed volume configured to carry a cryogenic fuel;
- and
- an outer vessel enclosing the inner vessel to define an insulating volume therebetween, the insulating volume comprising a vacuum, and the outer vessel comprising a vessel mount structurally connecting the inner vessel to the outer vessel and configured to isolate the inner vessel from static and/or dynamic loads carried by the outer vessel,
- wherein the outer vessel of the cryogenic tank comprises an integral structural member of the airframe.

An aircraft, comprising:
- an airframe configured to transmit aircraft flight loads,
- a propulsion system, and
- a cryogenic tank supplying the propulsion system, the cryogenic tank comprising
- an inner vessel defining a closed volume configured to carry a cryogenic fuel;
- an outer vessel enclosing the inner vessel to define an insulating volume therebetween, the insulating volume comprising a vacuum, and the outer vessel comprising
- a mounting member for structurally connecting the outer vessel of the cryogenic tank to the airframe at two or more longitudinally spaced mounting locations, the mounting member configured to transfer static and/or dynamic loads between the two or more longitudinally spaced mounting locations thereby permitting transfer of the static and/or dynamic loads from the airframe through the outer vessel in a longitudinal direction;
- and
- a vessel mount structurally connecting the inner vessel to the outer vessel and configured to isolate the inner vessel from said static and/or dynamic loads carried by the outer vessel.
