defensive spiral

名詞

(aviation, military) A last-resort defensive maneuver in dogfighting used by an aircraft with critically-low kinetic energy, consisting of a rolling scissors performed straight down, using gravity to supply the kinetic energy needed to continue maneuvering, while attempting to either slow down enough to get behind the attacker or else trick the attacker into crashing into the ground.

日本語の意味

航空戦において、極限まで運動エネルギーが失われた航空機が、直下に大回転（ローリングシザーズ）を行い、重力を利用して再度運動エネルギーを獲得しようとする、最後の手段の防御機動。敵の後ろに回り込むか、敵に地面衝突を誘わせるために実施される作戦。

When his airspeed bled away and the attacker closed in, the pilot executed a defensive spiral, a last-resort downward rolling‑scissors maneuver that used gravity to keep him maneuverable while he tried either to slow enough to get behind the attacker or to trick the attacker into crashing into the ground.

対気速度が尽きて敵機が接近すると、操縦士は降下するローリングシザーズによる最後の手段の防御機動を行い、重力を利用して機動を続けながら相手の後方に回り込むか、相手を地面に衝突させるよう仕向けようとした。
