GIRAVION PROVIDED WITH A ROTARY VESSEL AND AN ORIENTABLE PROPELLER, AND A METHOD APPLIED BY THIS GIRAVION

摘要

The present invention relates to a rotorcraft (1) comprising a fuselage (2) surmounted by a main rotor (30). The rotorcraft (1) comprises a first helix (10) and a second helix (20) rotated respectively about a first secondary axis of rotation (51) and a second secondary axis of rotation (52). A mobility system (60) rotates said second propeller (20) relative to the fuselage (2), said mobility system (60) moving said second secondary rotational axis (52) relative to the fuselage (2). a first position (POS1) where the second propeller (20) exerts a thrust (P2) in the first direction (S1) at a second position where the second propeller (20) exerts a thrust in a second direction opposite to the first direction (S1 ).
