PROCEDURE FOR TESTING SYNTHETIC-FIBER CABLES FOR FLEXING FATIGUE UNDER LOAD

摘要

The design, apparatus and procedure for testing the ability of synthetic cables to withstand rolling over a sheave (pulley-wheel) while under tension are described. The test is designed to be simulative of the use of tether-cables in flying large balloons. Because of the somewhat unusual nature of the test, the discussion section provides further detail on the significant of the test.
