A Design Study in Aluminum Castings -Uplock Support                                          

  Uplock Support  -- Conversion Benefits

The finished casting design for the uplock support had cost and performance benefits for both the aircraft manufacturer and the airline operator.
Benefits for the Aircraft Manufacturer

50% cost savings based on --
  • Part count reduction (35 parts in original fabrication)
  • Elimination of 25 shims, 2 assembly jigs, and 29 technical drawings.
  • Assembly cost savings with reduced tooling, simplified assembly process, shortened build time, tighter tolerances, fewer assembly errors, and easier fit-up/installation.
