This includes the design of rotor blades with the Active Gourney Flap active system which enables identification of the optimal configuration for the subsequent building of the parts for the validation tests, improvement of the helicopter-engine aerodynamic integration, reduction of airframe drag of the rotor through improved rotor fairing, more efficient electrical systems (brushless generators, electromechanical actuators, electrical tail rotor drive) and definition of new flight procedures with little noise emissions and optimised flight paths (including management of avionics missions).
