Abstract

Modern and promising blades of rotors and tail rotors of helicopters are almost entirely made of polymer composite materials. All these structures are extremely sensitive to operational damage, which can not only appear for a variety of reasons, but are also poorly detected visually from the outside, even with large areas of delamination and cracking of the base material. To solve the problems of detecting and measuring the size of operational damage, the selection of optimal options for non-destructive testing methods for each type of structure was made, the features of their application were studied, and the optimal settings and control modes were selected.
