Abstract

A gas turbine moving blade includes a platform which is undercut with a groove. The groove extends from the concave side to the trailing edge side of the platform, where the groove exits the platform. The groove has a depth which will enter a stress line causing a change to the load path direction away from the trailing edge. The location and depth of the groove reduces both high thermal stress and mechanical stress arising at a connection portion of a blade trailing edge and the platform of the gas turbine air cooled moving blade during transient engine operation as well as steady state, full speed, full load conditions.
