The primary objective of this thesis is to present an algorithm for numerical implementation that enables to simulate the dynamics of rotorcraft-load combinations. Executed in a numerical simulation environment such as MATLAB, the algorithm reproduces a predetermined kinematic motion of a helicopter and derives the consequent dynamics of all suspended loads, connected to it in any configuration, analyzing the state variables and the forces acting on the bodies. This master's thesis work was carried out in collaboration with Umberto Ciarlo, a university colleague, as a part of a broader project in which TPS Group S.p.A. is involved - a leading company in technical and engineering services for the aeronautical industry, and a leader in several other industrial sectors.
