The field of this disclosure relates generally to a rotor blade and method of fabricating the same and, more particularly, to cooling a rotor blade.
At least some known rotor blades include tip shrouds to prevent leakage of gases past the tips of the rotor blades and to facilitate increasing operating efficiency. However, known tip shrouds may experience creep due to temperatures and loading during operation. By reducing the temperature of the shrouds during operation, the service life of the shroud may be extended. However, known tip shroud cooling features add weight to the extremities of the shroud and may increase the bending stresses in the shroud fillet and the blade airfoil. Further, although known tip shrouds generally increase aerodynamic efficiency, known tip shrouds may be limited by a mechanical gap that sets the leakage across seal teeth.
One known...
