A new approach to the analysis of the processes of propagation of fatigue cracks in the blades of aircraft gas-turbine engines has been suggested and realized. The approach considers the peculiar features of the structure of the blades and their production process, operating conditions. Based on this approach a systematic theoretical and experimental investigation of the mechanism leading to the propagation of cracks in the blades have been made for the first time. The results of the work have been introduced at aircraft engine-building plants.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
