Naval Hovercrafts Specify improved Fasteners

摘要

The U.S. Navy is using a new vibration-proof fastening system designed to dramatically reduce maintenance and improve performance of its Hovercraft, also known as the Landing Craft, Air Cushion (LCAC). The ship is used by the U.S. Marine Corps to transport supplies, vehicles and troops to the shore from a Wasp class assault ship or other amphibious vessel. They can travel at up to 40 knots (46 mph) and can be mounted with two machine gun emplacements and 40 mm grenade launchers. They have been slowed in the past by damage to 100 rubber-pleated skirt pieces that fit to their lower portion. The previously used fasteners had to be removed with bolt cutters. Additionally, a 2-ft section had to be replaced even though only front sections were torn. "It is a very time-consuming and laborious task for the Navy personnel and requires them to climb under the Hovercraft," says Loren J. Ball, CEO of Permanent Technologies of Hauppauge, NY.
