Application of Boron/Epoxy Reinforced Aluminum Stringers and Boron/Epoxy Skid Gear for the Ch54B Helicopter Tail Cone. Phase 2 Fabrication, Inspection and Flight Test

摘要

A CH-54B Skycrane helicopter was fabricated with boron/epoxy reinforced stringers in the tail cone and boron/epoxy tubes in the tail skid. The fabrication of the tail cone was made with conventional tooling, production shop personnel, and no major problems. The flight test program includes a stress and vibration survey using strain gages and vibration transducers located in critical areas. The program to inspect and monitor the reliability of the components is discussed. (Author)
