Abstract : The authors describe a unit designed for studying the effect which internal fluid pressure, inaccuracies in assembly, vibration loads due to the power plant and pumps, and other factors have on the fatigue strength of pipeline connections in aircraft hydraulic systems. The procedure used for checking the fatigue strength of pipeline couplings is described in detail. The unit may be used for testing connections under conditions close to operational for long periods with sufficient accuracy for practical purposes.
