1. An airfoil for a gas turbine engine having a suction side wall on a suction side and a pressure side wall on a pressure side, said pressure side wall and said suction side wall extending from a leading edge to a trailing edge in a chordwise direction, said airfoil having a leading edge region, a mid-chord region, and a trailing edge region, said regions sequentially situated in said chordwise direction from said leading edge to said trailing edge, said mid-chord region having at least one suction side feed passage and at least one pressure side feed passage, said suction side feed passage being disposed on said suction side and bound by said suction side wall and a first inner wall, said pressure side feed passage being disposed between said pressure side wall and a second inner wall, a feed chamber being defined between said first inner wall and said second inner wall, said trailing edge region having at least one trailing edge passage disposed between said pressure side wall and said suction side wall, said airfoil characterized by:

  • a transition region disposed between said mid-chord region and said trailing edge region, said transition region having a transition feed passage and a transition chamber, said transition feed passage and said transition chamber being separated by said first inner wall extending from said mid-chord region into said transition region in said chordwise direction and bound by said suction side wall and said pressure side wall.
