Abstract
A supercritical wing of the variety in which the compression shock is stabilized is being improved by providing a suction device, substantially along the entire wing span, right at the chord station of the upper-wing surface where intercepting the sonic line. Specific rules concerning the suction and suction slit are given. A small chord station range may be covered by a movable slot or several parallel-running slots. The surface contour may be modified right at a slot to, thereby stabilize the compression shock further. The invention shifts buffet onset to larger off-design Mach numbers and angles of attack.
