The study is devoted to the problem of diagnosing damage in the blades of aircraft gas turbine engines in the engine operating mode. The study built a model that allows calculating the position of inclined cavities for installing capsules containing ionizing substances in the body of a turbine blade, which are used to detect cracks. When deriving the constitutive relationships for calculating the coordinates of the centers of the holes, angles of inclination, the provisions of vector algebra and analytical geometry were used. The results of the study can find practical application at the stage of designing gas turbine engine blades with a control system in non-stationary conditions. Keywords: turbine blade, shell, internal cavity, crack detection.
