Abstract : The report presents the results of a series of tests conducted to determine the operational suitability of using nylon 6/6 spiral cut tubing (coil) as a hose chafe guard on Army helicopters. These tests were part of a follow-on effort recommended in USAAMRDL Technical Report 72-1. The test effort was divided into five areas: Coil back-off tests; flight tests; temperature/ wear tests; fluid compatibility tests; and ozone, aging, and fungus investigations. Test results and material investigation indicated that nylon 6/6 spiral cut tubing is a good hose chafe guard for the temperature band from -65 degrees to 225 degrees F, and it is recommended for retrofit to Army helicopters where temperatures do not exceed those bounds.
