AIRFOIL WITH STEPPED SPANWISE THICKNESS DISTRIBUTION |
摘要 |
An airfoil in a gas turbine engine includes opposed pressure and suction sides joined together at chordally opposite leading and trailing edges. The pressure and suction sides extend spanwise from a root to a tip of the airfoil. The airfoil has a spanwise distribution of maximum thicknesses of chordwise cross-sections of the airfoil. The spanwise distribution of maximum thicknesses decreases from the root to the tip. In one aspect, the spanwise distribution is stepped between a first portion extending from the root and a second portion extending to the tip. |

1. An airfoil in a gas turbine engine, the airfoil comprising:
opposed pressure and suction sides joined together at chordally opposite leading and trailing edges, the pressure and suction sides extending spanwise from a root to a tip of the airfoil, the airfoil having a spanwise distribution of maximum thicknesses of chordwise cross-sections of the airfoil, the spanwise distribution of the maximum thicknesses decreasing from the root to the tip, the spanwise distribution being stepped between a first portion extending from the root and a second portion extending to the tip. |
