[en] The REDT (Rotor à Entraînement Direct par Turbine – Direct Turbine Driven Rotor) is a new concept for
helicopter rotor drives developed by Sagita in Belgium. It works without any mechanical link between the
engine on one side and the rotor drive on the other side. It uses a fuselage-mounted compressor that
powers two contra-rotating rotor-mounted free turbines. These free turbines drive a pair of contrarotating
rotors that are fitted with rigid hingeless main rotor blades. This novel rotor drive eliminates the
need for either mechanical transmission or a tail rotor. The aim of the REDT concept is to lower the
maintenance costs and the accident rate, as well as to extend the flight envelope towards much higher
airspeeds compared to classical helicopters.
