This paper deals with an efficient computational process for the synthesis of a low-frequency controller aimed at alleviating helicopter rotor blade–vortex interaction noise. It is based on an optimal, multicyclic, control approach that exploits di

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

Several sources of acoustic annoyance may be detected in a rotorcraft in operating conditions. The current research pays particular attention to the noise generated aerodynamically by the main rotor because of blade-vortex interactions (BVIs). This p
