The air intake includes two main flaps (1, 2) facing each other and each pivoting about a pin (4, 5) adjacent to a wall (6, 7) extending the flap in question (1, 2) rearwards, and in which a first boundary layer bleed (8a, 8b) is arranged, the pins (4, 5) being substantially parallel to the plane of

The air intake includes two main flaps (1, 2) facing each other and each pivoting about a pin (4, 5) adjacent to a wall (6, 7) extending the flap in question (1, 2) rearwards, and in which a first boundary layer bleed (8a, 8b) is arranged, the pins (4, 5) being substantially parallel to the plane of the wings or of the fuselage so that the flaps (1, 2) move perpendicularly to this plane, and a ramp (11) pivoting about a pin (12) adjacent to its leading edge (11a) by which it is adjacent to the wings and to the fuselage and substantially parallel to the pins (4, 5) is upstream of the flap (1) which is closest to the wings and with which it delimits another boundary layer bleed (13) of variable cross section.

A two-dimensional variable-geometry supersonic and hypersonic air intake, for the combustion air of an aircraft engine, placed under the wings or the fuselage of the aircraft and comprising two main flaps arranged face to face and each movable about a pivot axis situated in the vicinity of one wall

A two-dimensional variable-geometry supersonic and hypersonic air intake, for the combustion air of an aircraft engine, placed under the wings or the fuselage of the aircraft and comprising two main flaps arranged face to face and each movable about a pivot axis situated in the vicinity of one wall of the air intake which extends the main flap in question rearwards, in which wall is arranged a first boundary layer bleed, the pivot axes of the two main flaps being substantially parallel to the plane of the wings or of the fuselage, so that the abovementioned main flaps move perpendicularly to this plane, wherein a ramp, which is movable about a pivot axis substantially parallel to the pivot axes of the main flaps, and situated in proximity to its leading edge, is arranged upstream of the main flap closest to the wings or to the fuselage, this upstream ramp being adjacent, at its leading edge, to the wings or to the fuselage and delimiting, with said main flap, a boundary layer bleed of variable cross section and wherein the boundary layer bleed of variable cross section may be of zero cross section.
