Abstract:
A coolable fluid reaction element for a turbomachine, comprising:an airfoil having a pressure wall and a suction wall, each wall extending from an airfoil leading edge to an airfoil trailing edge, the walls having respective pressure and suction surfaces exposed to a stream of fluid in a fluid flowpath;forward and aft imperforate ribs extending laterally across the airfoil, each rib having a suction side terminus and a pressure side terminus, the suction side termini chordwisely delimiting a segment of the suction wall;an internal plenum for distributing a pressurized coolant, the plenum bounded by the ribs and the suction wall segment; andat least one array of cooling holes penetrating the suction wall segment, the at least one hole array being the exclusive avenue for conveying coolant from the plenum to the fluid flowpath.
