English Dictionary

bi-elliptic transfer

名詞

(astronautics) A type of movement of a spacecraft from one orbit to another, in which the spacecraft first raises its apoapsis to an extremely high altitude, then, at the new, higher, apoapsis, performs an engine burn to change its periapsis to that of the desired orbit, and, finally, upon reaching the new periapsis, performs a third burn to lower the eccentricity of its orbit and circularize in the desired orbit, or performs these steps in reverse to move from a higher to a lower orbit.

日本語の意味

（宇宙船の軌道操作の一手法）軌道間移行のため、まず軌道の遠地点（apoapsis）を極端に高くし、その後、新たな遠地点でエンジン燃焼を行って望む軌道の近地点（periapsis）に合わせ、最終的に近地点で再度燃焼して軌道の離心率を下げ、円軌道に整える（または逆の手順で）方法

To minimize propellant use for certain orbital changes, the mission controllers decided to employ a bi-elliptic transfer rather than a Hohmann transfer.

特定の軌道変更で推進剤の使用を最小限にするために、ミッション管制はホーマン転移ではなく双楕円軌道遷移を採用することに決めた。
