ABSTRACT:
An axially semisymmetrical supersonic air intake comprises a semiconical reaction engine displacer body having an air gap between the flat bottom of the air intake of the displacer body in the outer contour adjacent thereto of a missile or aircraft. The body transmits the boundary flow of the missile or aircraft and is bridged by a boundary layer plow. The body has a circumferentially distributed aperture on its surface in a zone of external normal shock which is produced during the subcritical conditions oscillating back and forth by which communication is established with the bleed air channel. The bleed air channels lead openings in the body to the flat bottom and may be subdivided by partitions in the interior of the body into individual parallel passages. The channels are formed by semiconical air baffles which are coaxial with the displacer body and taper in a direction opposite to the taper of the displacer body. The bleed air channels communicate with the inside of the boundary layer plow through outflow apertures at their ends which extend into the plow.
