Variable Wings - Variable Wings

Japanese: 可変翼 - かへんよく

A wing whose sweepback angle and aspect ratio can be changed according to flight conditions. Also known as a variable geometry wing (VG wing). Swept-back wings with a strong sweepback angle are effective at supersonic speeds and above, but they are less efficient during takeoff and landing and have many drawbacks. For this reason, a mechanism was developed that moves the wing back and forth around its base as a fulcrum during flight to change the sweepback angle, and was first put to practical use in the U.S. F-111A fighter in 1965.

Japanese:

飛行状態に応じて後退角やアスペクト比などを変えることのできる翼。VG翼（variable geometry wing）とも。強い後退角の後退翼は超音速以上では有効であるが，離着陸時には効率が劣り欠点が多い。このため飛行中に翼を，付け根を支点として前後に動かし，後退角を変化させる機構が開発され，1965年米国のF-111A戦闘機で最初に実用化された。
