  author={Giovanni Bernardini and Emanuele Piccione and Alessandro Anobile and Jacopo Serafini and Massimo Gennaretti},
An optimal procedure for the design of rotor blade that generates low vibratory hub loads in nonaxial flow conditions is presented and applied to a helicopter rotor in forward flight, a condition where vibrations and noise become severe. Blade shape and structural properties are the design parameters to be identified within a binary genetic optimization algorithm under aeroelastic stability constraint. The process exploits an aeroelastic solver that is based on a nonlinear, beam-like modelโ€ฆย CONTINUE READING
