Abstract:

The report presents the results of a series of tests conducted to determine the chafing characteristics of wire-braided hoses in an Army helicopter vibration environment. The tests were conducted by vibrating wire-braided hoses against one another until they failed or reached the predetermined termination test time. Failure was defined as a loss of hydraulic fluid through a worn or punctured lining at the point of contact. Once a mean time between failure was established for the unprotected no chafe guard hoses, various chafing protection schemes and materials were examined for their effectiveness.
