supercritical wing

… For high subsonic and supersonic aircraft, the selection of the wing type is also important, and various researches are being conducted on it. One such wing type is the supercritical wing, which has become widely used as a wing type for high subsonic jet transport aircraft. This is a design that theoretically calculates the wind pressure distribution on the wing surface and delays (increases) as much as possible the Mach number at which shock waves are generated on the wing surface at high subsonic speeds and drag increases rapidly. …

From [Wings]

...Also, from the end of the 1950s, airfoils that could delay the sudden increase in resistance without generating strong shock waves even when the flow speed on the wing surface slightly exceeded the speed of sound began to be used. Peaky airfoils and super critical wings belong to this category, and are collectively called transonic airfoils. Supersonic flight was realized in 1947. ...
