This paper summarises the results obtained by the staff of the University of Pisa and TELEAVIO Srl concerning a preliminary estimation of the hinge moments on the aerodynamic control surfaces of the tilt rotor (operating in the "Fixed Wing" mode), carried out in order to allow the pre-design of the actuators of the flight control system. The estimation was accomplished by means of two different methods (provided by ESDU and Hoerner ), whose results are then compared. The basic hypotheses are that the aerodynamic surfaces work in the linear range of incidence and control deflection. Nevertheless, an estimation of the hinge moments in the post-linear range of control deflection is also given.
