Abstract (en)
[origin: EP2666968A1] A turbine rotor blade 115 for a gas turbine engine is described. The turbine rotor blade 115 includes an airfoil that includes a tip 137 at an outer radial end. The tip 137 includes a rail 150 that defines a tip cavity 155; and the rail 150 includes a circumscribing rail microchannel 166. The circumscribing rail microchannel 166 is a microchannel that extends around at least a majority of the length of the inner rail surface 157.
