AIRFOIL WITH VARIABLE PROFILE RESPONSIVE TO THERMAL CONDITIONS
First Claim
Patent Images
1. An airfoil comprising:
- an airfoil body including a first section and a second section that differ by coefficient of thermal expansion, the second section being arranged in thermomechanical juxtaposition with the first section such that the first section and the second section cooperatively thermomechanically control a profile of the airfoil body responsive to varying thermal conditions.

Abstract
An airfoil includes an airfoil body having a first section and a second section that differ by coefficient of thermal expansion. The second section is arranged in thermomechanical juxtaposition with the first section such that the first section and the second section cooperatively thermomechanically control a profile of the airfoil body responsive to varying thermal conditions.
