English Dictionary

gravity drag

名詞

不可算名詞

(astronautics) The resistance felt by a vehicle ascending against the force of gravity; reduction in delta-v experienced as a result of the partial cancellation by gravity of the vertical component of the thrust applied by a vehicle's engine(s).

日本語の意味

（宇宙工学）上昇中の航空機や宇宙船が、重力に抗して上昇する際に受ける抵抗。すなわち、エンジンの垂直推力の一部が重力によって部分的に打ち消され、その結果、実際に得られるデルタVが低下する現象を指す。

During the launch, engineers carefully modeled gravity drag to ensure the rocket had enough thrust to reach orbit.

打ち上げ中、技術者たちはロケットが軌道に到達するための推力が十分であることを確認するため、重力による抵抗を慎重にモデル化した。

意味（1）

(astronautics) The resistance felt by a vehicle ascending against the force of gravity; reduction in delta-v experienced as a result of the partial cancellation by gravity of the vertical component of the thrust applied by a vehicle's engine(s).

For GTO missions, the launch vehicle follows a significantly shallower flightpath than for LEO missions, considerably reducing gravity drag at the expense of a significantly increased thermal loading and somewhat greater structural loads and aerodynamic drag.
