Abstract:

The program established the preliminary design, supported by preliminary analysis, of a 9-foot diameter cylindrical structure with an expanded length of 25 feet which attaches to the aft end of the MOL to serve as a pressurized meteoroid protective enclosure for astronauts working on MOL experiments. The expandable hangar construction is a composite wall consisting of an inner triple-barrier pressure bladder for gas retention, a web strap structural layer, a 2-inch thick polyether foam meteoroid barrier, and a film- cloth laminate outer cover with a thermal coating. The web straps carry the longitudinal pressure loads while the circumferential pressure loads are distributed from the web straps to a series of intermittently-spaced wire cable circumferential hoops. Flexible clam shell doors mounted to rigid frames at the aft end of the hangar can be opened and closed by a reel and cable system to provide an opening for large objects to pass thru when the hangar is unpressurized. The extended length of the hangar is maintained when unpressurized by 3 inflated 10 inch diameter full length deployment tubes while the shape is maintained by the foam barrier. Fabrication of the hangar, which is estimated to weigh 1459 pounds including the packaging canister, is entirely feasible and within the present state of the art.
