Abstract
A rotorcraft having a fuselage surmounted by a main rotor. The rotorcraft has a first propeller and a second propeller driven in rotation respectively about a first secondary axis of rotation and a second secondary axis of rotation. A mobility system turns the second propeller relative to the fuselage, the mobility system turning the second secondary axis of rotation relative to the fuselage from a first position where the second propeller exerts thrust in a first direction to a second position where the second propeller exerts thrust in a second direction opposite to the first direction.
