Advanced european tiltrotor dynamics and noise

Objective

The project is intended to enhance the EU knowledge on tilt rotor technologies by deeply analyzing the Whirl-Flutter, an aero elastic instability of the rotor/pylon system occurring at high inflow speeds typical of tilt rotors. The research is conducted by a comparison of analytical and experimental results. Tests will be done in a high-speed wind tunnel facility using a half-span scaled model. The availability of a wind tunnel model that is useful also for aero acoustic analysis will help optimize the rotor blade design for a low external noise level and, at the same time, a performance assessment in wind tunnel will demonstrate the validity of this design in all flight conditions. The project will provide final recommendations for the design of a full-scale tilt rotor flight demonstrator (ERICA).
