Abstract
【解決手段】低速肥大船の速度性能を向上させるために船尾のプロペラ前方に適用する前流固定翼1を設置するにおいて、前記前流固定翼を、船体伴流の特性及びプロペラ2の回転方向などを考慮して様々なタイプの非対称構造にして設置することで、効率向上及び重さ節減はもちろん、プロペラの負荷分布の均一化を図り、結果としてプロペラの効率及びキャビテーション特性を大きく向上させる。
【選択図】図1
Description
2 プロペラ
Claims (3)
- プロペラの効率及びキャビテーション特性を向上させるために、軸方向における中心線から船舶の左舷側に45°の間隔で放射状に設置された3枚の前流固定翼(1)を備えており、
