Abstract

The aim of this master’s thesis is to evaluate the impact in the dynamics of the Aérospatiale AS350 helicopter blade because of the modification performed to the tip and its potential loss during flight. Specifically, the Silent Eco Wing (SEW) replaces the original tip and is designed to modify the end vortices generated by the helicopter blade, thereby reducing noise and drag. This master's thesis work is carried out with Benedetta Maria Vittoria Borlizzi - university colleague – in collaboration with TPS Aerospace Engineering Srl, a leading company in the aerospace with expertise in aeronautical product and parts design and certification.

Multiple analyses are conducted to bring results that are always – going forward in the reading – more congruent with the actual case in terms of imbalance and change in the aerodynamic load developed
