Numerical Study of Influence of Inclined Crack Geometrical Characteristics in a Turbine Blade of the R-2617a Profile on a Failure Pressure in the Damage Detection System

The study examines the problem of detecting cracks in gas turbine blades during engine operation. A series of finite element calculations of the destructive pressure in the capsules of the crack detection system were carried out using the example of a turbine blade of the R-2617A profile. The influe...

Description
Summary:The study examines the problem of detecting cracks in gas turbine blades during engine operation. A series of finite element calculations of the destructive pressure in the capsules of the crack detection system were carried out using the example of a turbine blade of the R-2617A profile. The influence of geometric characteristics is analyzed, such as the width of a turbine blade crack opening, the angle of inclination of the crack to the radius, and the crack opening angle, on the pressure value, at which capsules with the active substance are destructed in the system for detecting damage of gas turbine blades.
