propulsion coefficientとは 意味・読み方・使い方

To provide a propulsion performance improving device for a vessel with a comparatively simple constitution, improving hull efficiency by increasing an effective wake coefficient without increasing a thrust reduction coefficient and providing a further excellent propulsion improving effect as compared with conventional propulsion performance improving devices.例文帳に追加

推力減少係数を増大させず有効伴流係数を増大させて船殻効率を向上させることができ、更に従来のものに比べて推進性能向上効果を得られる、比較的簡素な構成による船舶用推進性能向上装置を提供する。 - 特許庁
