Abstract: High pressure gas turbine blades are complex components that operate in the harshest environment within the turbine and are subjected to extreme temperatures. These conditions require that the blades be thoroughly inspected at multiple stages of their lives. In this paper we will provide evidence that an additional non-destructive examination, NDT-RAM, could greatly aid in improving the inspection practices of gas turbine blades. Implementing NDT-RAM as an inspection method for turbine blades can not only reveal defects and lifecycle fatigue that may be missed by other NDT inspection methods, but it can also reduce the time and cost of inspecting these critical and complex components.
