PROBLEM TO BE SOLVED: To provide turbine blades which increase the overall cooling efficiency in the turbine blades thereby possibly increasing the operational life of the blades, which may result in cost savings due to less frequent turbine blade replacement and reduced turbine engine down-time.SOLUTION: A system includes at least one gas turbine blade that includes at least one recess disposed in a surface of the at least one gas turbine blade. The system also includes a porous insert that includes multiple pores that enable a cooling fluid to flow through the porous insert. The system further includes a cover plate, where the porous insert is disposed within the at least one recess, and the cover plate is disposed over the porous insert to enclose the porous insert within the at least one recess. |
