Abstract:

Because of the recent high rejection rates on carbon steel control cables on military aircraft, the Air Force conducted breaking strength and endurance tests on various types of aircraft control cables. Since approximately 90 of the service life of jet aircraft is flown at low temperatures, the primary purpose of the tests was to obtain information on cable fatigue life at low temperature. The tests were conducted on 18-inch diameter 7x19 galvanized carbon steel, tin-coated carbon steel, and stainless steel cables at both low temperature -65 F and room temperature 70 F. The tests were conducted in the Climatic Laboratory at Eglin AFB, Florida. Results indicate that the stainless steel cables are far superior to the galvanized or tin-coated cables for low temperature operation. Therefore, the stainless steel cables should be considered for replacement of the carbon steel control cables on military aircraft, and the appropriate specifications should be updated accordingly.
