What is it about?

This paper enhances surrogate based optimization technologies to arrive at a good aerodynamic helicopter rotor design with less computational effort.

Why is it important?

The new method significantly reduces the turn-around times and thus reduces risks and costs during the development of a new helicopter.


This is a foundation for a method which is now applied to generate next generation rotors.
