The purpose of this thesis is to evaluate the change in the dynamics of the Aérospatiale AS350 helicopter rotor as a result of the modification performed to the tip and its possible loss during flight. The Silent Eco Wing replaces the tip of the original configuration and modifies the end vortices generated by the helicopter blade reducing both noise and drag generated. This master's thesis work is carried out with Piccitto Lorenzo - university colleague – in collaboration with TPS Aerospace Engineering Srl, a leading company in the aerospace field that deals with – among others – support for the design and certification of aeronautical products and parts.
