EVALUATION OF 1-1/2-INCH DIAMETER 6 X 25 FW LLRS PURCHASE CABLE IN THE RALS MARK 7 MOD 1 ARRESTING GEAR

Abstract

The Mark 7 Mod 1, as normally utilized in the fleet, is reeved with 1-3/8-inch-diameter 6 x 25 FW LLRS (Filler Wire, Lang Lay Round Strand) purchase cables. In an effort to increase the service life, 1-1/2-inch-diameter 6 x 25 FW LLRS purchase cables were reeved into the engine. Recent tests at the Naval Air Engineering Center (NAEC) with the larger cable indicated a significant increase in fatigue life when compared to the standard 1-3/8-inch-diameter purchase cable; however, before an extensive fatigue test program could be undertaken, it was necessary to determine the effects, if any, the larger diameter cable would have on arresting-gear performance. A total of 80 arrestments of A-3, A-4, F-4, and F-8 aircraft were conducted at the centerline and the 20-foot-to-port OFF- CENTER engaging positions. Ten of the A-4 arrestments were made with the sheave dampers inoperative in order to investigate aircraft arresting-hook/pendant dynamics.
