WHAT DOES SWEEPBACK MEAN IN ENGLISH?
Swept wing
A
swept wing is a wing planform favored for high subsonic and supersonic speeds, and is found on almost all jet aircraft in one form or another, as well as some high speed propeller aircraft. Compared with straight wings common to slower aircraft, they have a "swept" wing root to wingtip direction angled beyond the spanwise axis. This has the effect of delaying the drag rise caused by fluid compressibility near the speed of sound, increasing performance. The concept was first investigated in Germany as early as 1935, but it found no application until just before the end of the Second World War. Swept wings became common on second-generation post-war fighters like the MiG-15 and F-86 Sabre, which demonstrated a decisive superiority over the slower first generation of straight-wing jet fighters during the Korean War. Since then swept wings have become almost universal on all but the slowest jets. The term "swept wing" is normally used to mean "swept back", but other swept variants include forward sweep, variable sweep wings and pivoting wings. The delta wing also incorporates the same advantages as part of its layout.
Definition of sweepback in the English dictionary
