Systems and methods for creating and automating an enclosed volume with a flexible fuel tank and propellant metering for machine operations
An enclosed volume is provided for performing operations in space, or on any astronomical object, in a manner separated from aspects of the external environment. The enclosed volume can be a flexible container for a satellite. The enclosed volume can include a membrane having a fluid barrier layer and being configured to contain a propellant gas or fluid; and an expulsion device configured to expel material from the membrane. In a stowed configuration, the flexible container is contained within the satellite, and in a deployed configuration, the flexible container extends away from the satellite. The flexible container can inflate from one shape, in the undeployed configuration, to another shape, in a deployed configuration. The other shape can be toroidal or other appropriate shapes. The flexible container can provide bipropellant, blowdown, and gas/fluid metering functionality. Entertainment and game play can be enabled by the enclosed volume involving robots and other devices.
