  • Patent number: 7434355
    Abstract: An inflatable docking station for a Mars roving vehicle (Mars rover) provides a recharging station as well as a storage facility for the Mars rover during adverse environmental conditions. The docking station/garage allows for extended operational life for the Mars Rover, allows for the Mars rover to operate at the polar regions of Mars, where extreme cold conditions restrict rover operation, and provides for a warmer habitat for the Mars rover. Conventional planetary roving vehicles only be deployed from the warmer equator region of the planet surface. However, these roving vehicles may never explore the polar regions because the roving vehicle may not have enough stored power. The docking station/garage provides a remote outpost for, among other things, storing and recharging the Mars Rover to allow it to reach more remote areas.

  • Patent number: 6581334
    Abstract: A high strength T-joint for inflatable tubular is formed by forming a butt joint between the end of a first two tubular member and the side wall of a second tubular member. The opening in the side wall of the second tubular member is sized to match the end of the transverse support member so that a sealing flange can be applied to the inner surface of the joint to provide an airtight seal. A reinforcing flange comprising a disk-shaped piece of fabric having a center opening, is then bonded over the opening in the second tubular member. The center opening in the reinforcing flange is substantially smaller than the opening in the side rail member. Therefore the reinforcing flange substantially reduces the size of the discontinuity in the side wall of side rail member, thereby substantially increasing the circumferential (“hoop”) load capacity of the side wall of the side rail member and substantially increasing the rupture pressure of the joint.

  • Patent number: 6547189
    Abstract: An inflatable module comprising a structural core and an inflatable shell, wherein the inflatable shell is sealingly attached to the structural core. In its launch or pre-deployed configuration, the wall thickness of the inflatable shell is collapsed by vacuum. Also in this configuration, the inflatable shell is collapsed and efficiently folded around the structural core. Upon deployment, the wall thickness of the inflatable shell is inflated; whereby the inflatable shell itself, is thereby inflated around the structural core, defining therein a large enclosed volume. A plurality of removable shelves are arranged interior to the structural core in the launch configuration. The structural core also includes at least one longeron that, in conjunction with the shelves, primarily constitute the rigid, strong, and lightweight load-bearing structure of the module during launch.

  • Patent number: 6463699
    Abstract: An air beam structure having reduced weight, increased rigidity, and lower inflation pressure requirements. The structure includes a closed tubular cylindrical shell of air impermeable fabric having at least one inflation valve. Fixed within the shell is an “I” beam envelope comprised of flexible, air impermeable walls sealed to the interior of the shell. The “I” beam envelope extends the length of the shell and defines at least four air chambers in communication with the inflation valve. A quantity of compressible material is dispersed throughout the interior of the “I” beam envelope. When subjected to compressive forces by pressurization of the air chambers, the material becomes rigid. The filled envelope is either vented to atmosphere or connected to a vacuum source. The air beam is used in groups and may be connected one to another by sheet materials to form a wall or roof structure.
