Forward-swept wing

A forward-swept wing or reverse-swept wing is an aircraft wing configuration in which the quarter chord line of the wing, from root to tip, has a forward sweep. Typically, the leading edge also sweeps forward. Forward-swept wings allow aircraft to safely sustain higher attack angles, making them more maneuverable, but introduce other aerodynamic instabilities.

Research into forward-swept wings began in the early 20th century, continuing after World War II in a limited capacity.
