A cryogenic pressure container for a motor vehicle has an inner container and an outer container. An evacuated space is arranged between the inner container and the outer container at least in some regions. The inner container has a synthetic material layer. A barrier layer is arranged at least in some regions between the synthetic material layer and the evacuated space. The barrier layer is designed and arranged so as to at least reduce the transfer of constituents leaking out of the synthetic material layer into the evacuated space, wherein a gap is formed at least in some regions between the barrier layer and the synthetic material layer.

The application provides an autonomous refueling vehicle for a hydrogen-electric aircraft, which includes two or more wings. The wings are provided with one or more removable electric propulsion pods. The autonomous refueling vehicle includes a hydrogen refueling module adapted to connect to the propulsion pods and to a hydrogen source. The autonomous refueling vehi-cle includes also includes a propulsion pod handling device, which is adapted to remove the propulsion pod from the wings and to position the propulsion pods on the hydrogen refueling module such that the propulsion pods are connected to the hy-drogen refueling module. The autonomous refueling vehicle is also adapted to autonomously move itself to the hydrogen source to allow the hydrogen refueling module to removably connect to the hydrogen source for refueling of the propulsion pods.

Cryogenic propellant tank (1) for a spacecraft engine, comprising an external enclosure (10) defining an internal volume, characterized in that the internal volume of the tank comprises a primary volume (V1) and a secondary volume (V2) connected to the primary volume (V1) via a valve (20) configured to selectively allow a passage of fluid from the primary volume (V1) to the secondary volume (V2), or to isolate the secondary volume (V2) from the primary volume (V1), the primary volume (V1) having a primary orifice (11) adapted to be connected to a first pressurization source (41), the secondary volume (V2) having a supply orifice (4) adapted to be connected to a supply line of a spacecraft engine (30), and a secondary orifice (12) adapted to be connected to a second pressurization source (42).

A low vibration cryostat includes a cryocooler with a cold head having a flange and a cooling body extending from the flange. A housing is coupled to the cold head, with the housing having an opening receiving at least a portion of the cooling body. A first bellows extends between the housing and the flange to mitigate the transfer of vibrational forces between the housing and the flange. The first bellows, the flange, and the housing collectively define a first chamber. A force balancing assembly containing a second bellows is coupled to the housing and includes a second chamber spaced from the first chamber. The two chambers are arranged to create a net zero force on the cold head when the pressure in the bellows changes. A viscous damping assembly mitigates bouncing of the cold head on support springs.
