Description
かかる船舶の航行抵抗低減及び船舶の方向転換補助が可能な装置は、船首水線下の前端位置に1台の三方向管が設けられ、前記三方向管は、外形略逆Y字形に形成された構造であり、それぞれ船首の前端と、両舷の船体外板とへ連通し、三方向管内に、少なくとも1つのバルブ(または整流案内装置)が設けられており、当該バルブ(または整流案内装置)は、水流偏向を制御可能であり、水流が前方の流路に流入し、バルブ(または整流案内装置)によって水流偏向を三方向管の左向き流路に向ける場合には、船舶の右向きの方向転換を補助可能であり、バルブ(または整流案内装置)によって水流偏向を三方向管の右向き流路に向ける場合には、船舶の左向きの方向転換が補助可能な構造としたものである。
・ 船首喫水線下の前端位置に1台の三方向管が設けられ、前記三方向管は、外形略逆Y字形に形成された構造であり、それぞれ船首水線下の前端と、両舷の船体外板とへ連通し、前記三方向管内に、船舶航行のメインシステム体系が装着されずに、船舶の方向転換補助のための少なくとも1つのバルブのみが設けられており、当該バルブは、水流偏向を制御可能であり、水流が前方の流路に流入し、当該バルブによって水流偏向を前記三方向管の左向き流路に向ける場合には、船舶の右向きの方向転換を補助可能であり、当該バルブによって水流偏向を前記三方向管の右向き流路に向ける場合には、船舶の左向きの方向転換を補助可能であることを特徴とする船舶の航行抵抗低減及び船舶の方向転換補助が可能な装置。
本発明は、前記の通り、船舶の航行抵抗を低減させ、また、方向制御を効率的補助可能な装置を提供することができるので、燃料消費量を低減させることができ、産業上の利用可能性も極めて大きい。
