Abstract
A turbine blade is disclosed. The turbine blade may include a platform, an airfoil extending from one side of the platform, and a neck extending from another side of the platform, wherein the neck includes a forward buttress and an aft buttress. The turbine blade may further include a root extending from the neck, a pocket defined by a plurality of walls and located between the forward. buttress and the aft buttress, and a variable radius fillet. The variable radius fillet may be disposed within the pocket and extend between the forward buttress and the aft buttress, wherein a radius of the variable radius fillet increases from the forward buttress to the aft buttress.
Claims20
A turbine blade comprising:
- a platform;
- an airfoil extending from one side of the platform;
- a neck extending from another side of the platform, wherein the neck includes a forward buttress and an aft buttress;
- a root extending from the neck;
- a pocket defined by a plurality of walls and located between the forward buttress and the aft buttress;
- and
- a variable radius fillet disposed within the pocket and extending between the forward buttress and the aft buttress, wherein a radius of the variable radius fillet increases from the forward buttress to the aft buttress.
A gas turbine engine comprising:
- a compressor system configured to compress a flow of air;
- a combustor system configured to combust a mixture of the air and a fuel to produce a hot gas flow;
- and
- a turbine system configured to use the hot gas flow to produce power, wherein the turbine system comprises:
- a plurality of turbine blades comprising:
- a platform;
- an airfoil extending from one side of the platform;
- a neck extending from another side of the platform, wherein the neck includes a forward buttress and an aft buttress;
- a root extending from the neck;
- a pocket defined by a plurality of walls and located between the forward buttress and the aft buttress;
- and
- a variable radius fillet disposed within the pocket and extending between the forward buttress and the aft buttress, wherein a radius of the variable radius fillet increases from the forward buttress to the aft buttress.
A turbine blade comprising:
- a platform;
- an airfoil extending from one side of the platform;
- a neck extending from another side of the platform, wherein the neck includes a forward buttress and an aft buttress;
- a root extending from the neck;
- a pocket defined by a plurality of walls and located between the forward buttress and the aft buttress;
- and
- a variable radius fillet disposed within the pocket, wherein the variable radius fillet extends between the forward buttress and the aft buttress, and wherein an amount of material forming the variable radius fillet is greater adjacent the aft buttress than adjacent the forward buttress.
