Gliding - gliding

Japanese: 滑空 - かっくう(英語表記)gliding
Gliding - gliding
When an airplane or glider descends at a gentle angle without engine thrust. The angle between the flight path and the ground is called the glide angle, the ratio of the distance traveled to the altitude reached during that time is called the glide ratio, and the loss of altitude per unit time is called the sink rate (or descent rate). The better the performance of the glider, the higher the glide ratio, exceeding 40:1 for a high-performance soarer. In other words, if it starts gliding from an altitude of 1000m, it can fly as far as 40km, and if there is an updraft during that time, it can regain altitude and continue flying. (→ Glider )

飛行機や滑空機 (グライダー) がエンジン推力のない状態で,ゆるい角度で降下すること。降下してゆく飛行経路と地面とのなす角度を滑空角,前進する距離とその間に沈下する高度の比を滑空比,単位時間内の高度低下を沈下率 (または降下率) という。滑空比は性能のよいグライダーほど大きく,高性能のソアラーでは 40:1をこえる。すなわち高度 1000mから滑空を始めると 40kmの遠方まで飛ぶことができ,その間に上昇気流があれば再び高度をとって飛び続けることができる。 (→グライダー )
