BUCKET AIRFOIL FOR A TURBOMACHINE |
| 摘要 |
A turbomachine bucket airfoil includes a root end, a tip end spaced from the root end, and an airfoil surface extending between the root end and the tip end. The airfoil surface includes an upstream edge, a downstream edge, a pressure side and a suction side defining a natural blade profile. The airfoil surface includes a blade span zone having a part span shroud zone. A first part span shroud projects outwardly of the pressure side in the part span shroud zone, and a second part span shroud projects outwardly of the suction side in the part span shroud zone. The turbomachine bucket airfoil includes an interruption of the natural blade profile in the part span shroud zone. |

1. A turbomachine bucket airfoil comprising:
a root end; a tip end spaced from the root end; an airfoil surface extending between the root end and the tip end, the airfoil surface including an upstream edge, a downstream edge, a pressure side and a suction side defining a natural bucket profile, the airfoil surface including a blade span zone defining a part span shroud zone; a first part span shroud projecting outwardly of the pressure side in the part span shroud zone; a second part span shroud projecting outwardly of the suction side in the part span shroud zone, wherein the turbomachine bucket airfoil includes an interruption of the natural bucket profile in the part span shroud zone. |
