ROTORCRAFT PROVIDED WITH AN AERODYNAMIC DEVICE COMPRISING A FAIRING HAVING AN AIR INTAKE

摘要

The present invention relates to a rotorcraft (1) comprising an aerodynamic device (2) arranged below a rotor (3) participating at least in the lifting of said rotorcraft (1) in the air, said rotor (3) rotating around it. a first axis of rotation (OZ) said aerodynamic device (2) comprising a fairing (4) having at least one air inlet (5) to allow a flow of a flow of fresh air between an area located at the outside of said rotorcraft (1) to another zone located inside said rotorcraft (1), According to the invention, at least at one mouth (6) of said at least one air inlet (5) of said fairing (4) ), said aerodynamic device (2) comprises at least one flap (V1, V2, V3) movable in rotation, said at least one movable flap (V1, V2, V3) comprising at least one degree of freedom in rotation around a second axis of rotation (O sub 1 /sub Y sub 1 /sub, O sub 2 /sub Y sub 2 /sub, O sub 3 / sub Y sub 3 /sub) with respect to said fairing (4), said at least one movable shutter (V1, V2, V3) orienting itself automatically and passively as a function of a current orientation of said flow of fresh air at the level of said mouth (6) of said air inlet (5).
