I am looking to know the main differences between scimitar and regular propellers. Can somebody help me on this?
The scimitar's swept back design results in less drag. On top of that it lets you increase the overall length of the propeller's airfoil without lengthening the diameter of the propeller. And since lengthening the propeller's diameter results in the tip of the blade traveling at a higher mach, the scimitar gives you all the benefits of a longer airfoil with none of the noise or drag penalties associated with a transonic propeller tip.
