| | The large prop-rotors on Tilt Rotor aircraft are required to work effectively in helicopter mode as an edgewise rotor and as a propeller in airplane mode. They are also required to generate and sustain the manoeuvre loads in these flight regimes and also during conversion mode when the nacelles can be fixed at intermediate angles, e.g. 60deg. These requirements introduce significant structural and aerodynamic design challenges but also opportunities. " XV15 research aircraft during conversion "... |

| | In airplane mode, the tilt-rotor functions exactly the same as a typical airplane.... Between the two modes of flight, the rotor operates in very different conditions, and power sensitivity to small changes in collective pitch is much higher in airplane mode than in hover : this explains the requirement for the specific work included in this workpackage on tilt-rotor power / thrust management.... |
