Abstract
A fan blade that responds to external perturbations in a way that reduces the effect of the perturbations on the blade. The fan blade is designed so that the twist center is forward of the pressure center relative to the air flow direction, and the distance between the twist center and the pressure center is greater than zero. Fan blades having this feature will deform in a way to decrease aerodynamic load when conditions cause an increase in aerodynamic load and conversely increase aerodynamic load when conditions cause a decrease in aerodynamic load.
