Turbine airfoil with weight reduction plenum

An airfoil for a gas turbine engine includes: opposed pressure and suction sidewalls extending between spaced-apart leading and trailing edges, a root, and a tip; and a hollow plenum disposed between the sidewalls. The plenum has a chordwise first dimension at a radially outer end thereof, and a cho...

Zusammenfassung:	An airfoil for a gas turbine engine includes: opposed pressure and suction sidewalls extending between spaced-apart leading and trailing edges, a root, and a tip; and a hollow plenum disposed between the sidewalls. The plenum has a chordwise first dimension at a radially outer end thereof, and a chordwise second dimension at a radially inner end thereof. The second dimension is substantially less than the first dimension.
