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.
Claims17
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.
A turbomachine comprising:
- an airfoil including an airfoil body having 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.
A method of controlling an airfoil profile, the method comprising:
- controlling a profile of an airfoil body in response to varying thermal conditions by thermomechanically juxtaposing a first section and a second section of the airfoil body that differ by coefficient of thermal expansion.
