Abstract

Cases of in-service fatigue crack growth in aluminium longerons of helicopter Mi-8 rotor blades were reviewed. Fatigue fracture surface patterns for micro- and meso-scale levels of crack growth mechanisms for in-service fatigued longerons are discussed. Meso-beach-marks were used to estimate the fatigue crack growth period in one of the damaged longerons with the least crack size. Results of these estimations showed the effectiveness of the special device in in-service operation, which was used in longerons for in-service fatigue crack detection.
