ENGINE AIRFOILS AND METHODS FOR REDUCING AIRFOIL FLUTTER

摘要

A method is provided for designing an airfoil. The method includes considering a baseline airfoil (510) having a first camber distribution (540) and a first aerodynamic efficiency; reducing the first camber distribution (540) to result in a reduced camber airfoil (560) with a second camber distribution (590) and a second aerodynamic efficiency such that the second aerodynamic efficiency is approximately equal to the first aerodynamic efficiency; and producing the airfoil with the second camber distribution.
