X-Plane 11/10 X3_Proto Windows V1

L ' X3 uses a cell of helicopter Eurocopter Dauphin equipped with a main rotor for five pales drawn away by two turbines and of two aircraft propellers taken up on short fixed wings. This hybrid shape gives birth to an apparatus of advanced transport which conjugates the speed of a plane with turboprop engine and the capacities of stationary flight of a helicopter. In cruise, wings take the intermediary of the main rotor for the lift. The rotor adopts a "flat" contour, where trail is trifling. Potency is then transferred towards aircraft propellers.

X3 pilots as a classical helicopter until 80 kt. Beyond, an additional order intervenes. It is about a button of trim electrical which augments the step of aircraft propellers and therefore the potency which they provide. It is necessary to reduce collective of the main rotor at the same time the not.

An important stage was crossed on May 12th of this year when the demonstrator broke his own record of speed by stealing some minutes at the speed of 430 km / h (232kt) during a flight of tries on the basis of Istres.
