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.
Navy Cost Avoidance:
Annual: $1,500 K
15 Year: $22,500 K
Impact: Potential significant reduction in elevator
down-time and maintenance. Reduced impact on flight operations.
new project was aproved by the January 31, 2003 Navy Working Group. Efforts
will immediately commence after receipt of Navy Technical Direction.
