Abstract
Two dimensional, supersonic and hypersonic air intake for the combustion air of an aircraft engine, comprising two front flaps (3) forming a visor, disposed symmetrically on each side of a longitudinal plane (P), each front flap (3) being movable about a pivoting axis (4) situated in the vicinity of the wall of the air intake which extends the front flap considered. The pivoting axis (4) of each front flap (3) is situated in the vicinity of a first boundary layer trap (5) disposed in the wall of the air intake which extends said front flap (3).
