AIRCRAFT CARRIER ELEVATOR (ACE) ROLLER GUIDES

CVN Elevator Rollers

Problem: Aircraft Carrier Aircraft Elevators require 8 sets (of 2 each) roller guides to maintain the alignment of each elevator platform as it moves up and down. These devices are completely open to the seas and atmosphere. They require regular and thorough lubrication. If the grease is lost or solidifies, the bearing seizes, rendering the elevator inoperable (affecting flight operations). Replacement of a single set of bearings must be done in port and costs $500K. The fleet estimates that an average of three sets must be replaced annually.

Solution: No immediate solution is available. The fleet has, for years, attempted to solve the problem by incorporating quick fixes. None have been satisfactory. MTTC has been asked to investigate all new technologies for potential solutions.

Benefits

 

Estimated Navy Cost Avoidance:

 

Minimum Annual:       $1,500 K

Minimum 15 Year:    $22,500 K

 

Fleet Impact: Potential significant reduction in elevator down-time and maintenance. Reduced impact on flight operations.

Status: Ongoing

 

This new project was aproved by the January 31, 2003 Navy Working Group. Efforts will immediately commence after receipt of Navy Technical Direction.

    Applications:
  • All Aircraft Carriers
