In this study, damage to AMAD gear lubricant tubes used in power generation as well as in the hydraulic/fuel pump operation of jet fighters is analyzed. Through fracture-surface analysis and natural frequency investigation via the ping test, resonance is specified as the cause of damage, and an improved design shape is proposed. The enhanced tube is validated for fluid and structural safety through natural-frequency analysis and engine operation tests. The result indicate that the rigidity of the system for propulsion and AMAD can be guaranteed, thereby securing aircraft reliability and improving quality.
