Endurance Test on Flexible Steel Wire Rope for Aircraft Controls at Various Pulley/Rope Diameter Ratios
Abstract
During previous investigations into the endurance properties of flexible steel wire rope for aircraft controls, large losses in strength were noted when small test pulleys were used. In view of this, a program of tests has been carried out to investigate the effects of test pulley size on the endurance of 1/8 inch diameter carbon and corrosion resistant steel ropes. A range of test pulley/rope diameter ratios between 7 and 30 has been investigated and the results of these tests are given in the report. The indications are that pulley to rope ratios of the order of 20 to 1 are desirable to ensure good endurance properties. The report also shows that under the particular conditions of test used (ie room temperature) corrosion resistant steel showed the better endurance properties.
