This program evaluated 8000 psi plumbing hardware using 3AL-2.5V titanium as the basic tubing material for high temperature, high performance plumbing systems. This program also evaluated and selected from a field of existing, types the most promising permanent joint and detachable tube fittings, hoses, swivels and quick disconnect fittings for use in an advanced aircraft hydraulic system. The major objective of this program was the development of design criteria with a high probability of producing a leakproof system over the life of advanced aircraft. The program developed the design criteria through review of design features of current system components, types of failures experienced in operational aircraft and the assembly, manufacturing and installation problems that exist with current fittings definition of the expected installation environment and experience. In conjunction with the establishment of the design criteria, an impulse test was conducted to compare the results of the current conventional damped wave method with an impulse fatigue method using sine wave shaped impulses.
