ARRESTING ENGINE WIRE ROPE TESTS,
DOUGLAS AIRCRAFT CO INC EL SEGUNDO CALIF
Pagination or Media Count:
The results are presented of abrasion tests conducted on various constructions of arresting engine wire rope. The wire ropes were comparatively tested to determine which construction is the best for further investigation, i.e. tests conducted on an actual arresting gear using a dummy weight andor the wire ropes being evaluated aboard a carrier during actual arrestments. The results of the tests indicate that the present wire rope has the lowest service life of any of the 6 x 25 or 6 x 30 flattened strand construction furnished for evaluation. It was determined that the life of the wire rope is increased by using a wire rope core instead of a fibre core and that using a lang lay rope is superior to a regular lay rope. The wire rope showing the maximum life under the higher load conditions was a 6 x 30, flattened strand, lang lay, and wire rope core. Author
