Two-dimensional supersonic and hypersonic air intake, with three mobile ramps, for the combustion air of an aircraft engine.

摘要

The air inlet comprises two main flaps (1, 2) facing each other and each pivoting around an axis (4, 5) adjacent to a wall (6, 7) extending rearwardly the flap (1, 2) considered, the axes (4, 5) being substantially parallel to the plane of the airfoil so that the flaps (1, 2) move perpendicular to this plane, and an upstream ramp (11) pivoting around an axis (12) close to its leading edge (11a) and substantially parallel to the axes (4, 5) is in front of the upper flap (1) with which it defines a boundary layer trap (13), which is closed when the engine is running in superstatorjet.
