Flight Configuration Redesign of the HUNCH ISS Galley Table-Strut Supports
Primary Function: To hold the table in set positions and add resistance to movement if a push or pull force is imported by the crew.
Operations: Maintain the one-handed operation.
Can a COT be identified to eliminate or greatly reduce any machining or modification.
Items to consider: Can it become jammed, partial deployment, unintended collapse?
Mounting Points: Match the redesigned table, such as handrails or seat track buttons as on the existing table.
Clearance and work envelop: Avoid creating pinch points with the table being placed in positions not at 90 degrees to the rack face.
Attachment method: Review the current system. The redesign should require no tools and be easily attached to the table and seat track on a rack.
Positive Lock: when locked, the strut should not have positional creep under crew loads or environmental vibrations.
Position references: Add reference marks to aid in the resetting of the table position and indicating a locked / unlocked condition.
Lubricants on the Strut: None that could be transferred to the crew or any materials. Non-migrating, space accepted per NASA accepted lists
Actuators: Large knobs that can easily be activated.
Pinch Points: Check your design for finger-safe clearances.
Captivity: Any loose items will need a Teather to prevent loss.
Materials: Materials such as Aluminum or Stainless Steel or other aerospace materials.
Thoughts: do we continue with the pip pin system that locks in at distance intervals determined by the spacing of the drilled holes, could a system such as used on camera tripod legs work? Lever locking or twist friction lock?
Can we color a locked or unlocked condition?
