VALIDATION OF DESIGN THEORY FOR AIRCRAFT ARRESTING-GEAR CABLE
Abstract
The five wire ropes selected for evaluation included four flattened- strand and one round-strand construction. The standard rope design presently in use for deck pendants was used as a basis of comparison for all tests. These wire-rope constructions were subjected to a series of tests to establish their suitability for use as arresting cable. The report discusses the selection of the new rope designs and the results of the testing program. Tests on these wire ropes included evaluation of (1) ultimate strength, (2) elastic modulus, (3) torsion, (4) flexibility, and (5) resistance to damage by transverse impact. The tests of ultimate strength, elastic modulus, and torsion were conducted in the test laboratories of the rope manufacturers. Rope tension, torsion, and elongation were measured. Tests of flexibility and resistance to transverse impact were conducted. The transverse-impact tests required the design and construction of special apparatus utilizing an explosive-powered arresting hook. With this equipment, specimens of each wire-rope construction were impacted with the arresting hook at velocities equivalent to the landing speeds of aircraft on carriers. These impact tests proved to be the most satisfactory method of evaluating deck-pendant ropes in the laboratory.
