Design and Fatigue Testing of Integral Armored Servo Actuator Modified Trunnion

Abstract

The program summarized by this report was conducted to design and establish the structural strength of a modified trunnion design for the integral armored servo actuator. The originally designed trunnion was found to have a fatigue strength below the mean strength level of comparable CH-54B parts as reported in USAAMRDL Technical Report 73-25. The design analysis and fatigue test data show that the modified trunnion is comparable in strength to the mean strength levels of the equivalent components on the production CH-54B helicopter.
