Abstract
An airfoil includes an airfoil section that has an airfoil wall that defines an arced leading end, a trailing end, and first and second sides that join the arced leading end and the trailing end. The first and second sides span in a longitudinal direction between first and second ends. The airfoil wall circumscribes an internal core cavity. There is an arced rib in the internal core cavity. A cooling passage network is embedded in the airfoil wall between inner and outer portions of the airfoil wall. The cooling passage network has a trailing edge and an arced leading edge.
Claims19
An airfoil comprising:
- an airfoil section having an airfoil wall defining an arced leading end, a trailing end, and first and second sides joining the arced leading end and the trailing end, the first and second sides spanning in a longitudinal direction between first and second ends, the airfoil wall circumscribing an internal core cavity, and the trailing end being straight;
- an arced rib in the internal core cavity;
- and
- a cooling passage network embedded in the airfoil wall between inner and outer portions of the airfoil wall, the cooling passage network having a trailing edge and an arced leading edge, the arched leading end, the arced rib, and the arced leading edge of the cooling passage network being arced such that profiles of the arched leading end, the arced rib, and the arced leading edge when taken in a radial cross-section are arced.
A gas turbine engine comprising:
- a compressor section;
- a combustor in fluid communication with the compressor section;
- and
- a turbine section in fluid communication with the combustor,
- the turbine section having a turbine airfoil that includes
- an airfoil section having an airfoil wall defining an arced leading end, a trailing end, and first and second sides joining the arced leading end and the trailing end, the first and second sides spanning in a longitudinal direction between first and second ends, the airfoil wall circumscribing an internal core cavity, and the trailing end being straight,
- an arced rib in the internal core cavity, and
- a cooling passage network embedded in the airfoil wall between inner and outer portions of the airfoil wall, the cooling passage network having a trailing edge and an arced leading edge, the arched leading end, the arced rib, and the arced leading edge of the cooling passage network being arced such that profiles of the arched leading end, the arced rib, and the arced leading edge when taken in a radial cross-section are arced.
