Gas turbine engine component having suction side cutback opening
View Patent ↗An airfoil for a gas turbine engine, according to an exemplary aspect of the present disclosure includes, among other things, a pressure side wall and a suction side wall spaced apart from the pressure side wall and each extending between a leading edge portion and a trailing edge portion. A plurality of cutback openings are spaced along a radial axis of the suction side wall.
1. An airfoil for a gas turbine engine, comprising:
a pressure side wall and a suction side wall spaced apart from said pressure side wall and each extending between a leading edge portion and a trailing edge portion;
a plurality of cutback openings formed in said suction side wall and that are spaced along a radial axis of said suction side wall such that a distal most portion of said suction side wall is offset from a distal most portion of said pressure side wall at each of said plurality of cutback openings;
said pressure side wall excluding any cutback openings at said trailing edge portion; and
wherein a gas path decelerating region of said suction side wall does not include film cooling holes.
2. The airfoil as recited in claim 1 , wherein said plurality of cutback openings are positioned at said trailing edge portion of said suction side wall.
3. The airfoil as recited in claim 1 , wherein at least a portion of said plurality of cutback openings are slots.
4. The airfoil as recited in claim 1 , wherein said plurality of cutback openings are positioned along an entire radial span of said suction side wall.
5. The airfoil as recited in claim 1 , wherein a rib extends between adjacent cutback openings of said plurality of cutback openings.
6. The airfoil as recited in claim 1 , comprising at least one film cooling hole at said trailing edge portion of said pressure side wall.
7. The airfoil as recited in claim 1 , comprising at least one film cooling hole in a gas path accelerating region of said suction side wall.
8. The airfoil as recited in claim 1 , wherein said distal most portion of said pressure side wall extends distally further than said distal most portion of said suction side wall.
