…In contrast, in a lift trajectory, the deceleration is gradual and the aircraft has maneuverability, making it possible to change the landing point. This trajectory can be further divided into an equilibrium glide trajectory and an L / D program trajectory. In the former, the lift-to-drag ratio L / D is constant, and the aircraft oscillates around the glide trajectory as it descends. … *Some of the terminology that refers to "L/D Program Orbit" is listed below.

…これに対し,揚力を利用した揚力軌道では,減速度が緩やかで,運動能力もあるので着地点の変更が可能となる。この軌道は,さらに平衡滑空軌道とL/Dプログラム軌道に分けられる。前者は,揚抗比L/Dが一定の場合で,滑空軌道のまわりを振動しながら降下する。… ※「L/Dプログラム 軌道」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
