What it is

Fixed aerodynamic plate mounted on top of an aircraft's swept wing, parallel to the chord, that blocks spanwise airflow to prevent the whole wing stalling suddenly; attributed to German engineer Wolfgang Liebe.

Exact date and place uncertain: attributed to Wolfgang Liebe around 1940 without a source pinning down the specific location.

What it led to

  • improved safety of swept wings
  • aerodynamic design of jet aircraft
  • boundary-layer control devices (slats, vortex generators)
  • high-speed commercial aviation
