Abstract

一种船舶船体型式结构，船舶的船体包括两个船艏部的船艏，和由船艏延伸至船艉的船身段，两船艏部的末端间隔有一定距离，然后向船身段方向延伸时逐渐接近并连接，且它们之间的底部形状也从两只船只的形状逐渐过渡为单体船线型，并最终与船身段的底部形状相吻合，同时在两船艏部之间设置气泡减阻装置，这些气泡减阻装置产生大量的气泡。该船舶船体型式结构通过双体船的船艏和单体船的船身，并结合气泡减阻技术，既可以有效提高船舶的航速并极大地降低所需的能耗，同时又具有单体船型舱容大、湿表面积小等优点。

Description

一种船舶船体型式结构
技术领域
本发明涉及船舶领域，特别是涉及一种船舶的船体型式结构。
背景技术
传统船只的底部近似于细长的碗型，其龙骨由船艏沿底部中线延伸至船艉。船只航行的动力由安装于船只内的主机提供，主机的功率也决定了船只的航行速度，若需要提高船只的航行速度，如在中高航速的船舶中，只能通过增加主机的功率以克服高速带来的阻力，但这需要消耗巨大的能源。为此，除了提供动力的主机之外，船舶领域中还会研究各种各样可以有效提高航速的办法和装置。
发明内容
本发明的目的在于提供一种能够提高船舶航速的船体型式结构，以降低船舶航行所需的能耗。
本发明所述的船舶船体型式结构，包括两个并列设置的船艏部，两船艏部之间留有间隙，两船艏部向船舶中部延伸并相连接，且两船艏部连接端底部与船体基线所在平面所围的空间，从船艏向船舶中部方向逐渐减少并过渡为单体船底部线型。
所述的船舶船体型式结构，两船艏部的底部相对侧处分别安装有产生气泡的气泡减阻装置；且两船艏部沿船舶中线方向的不同位置分别设置有气泡减阻装置。
本发明所述的船舶船体型式结构，船舶的船体分为船艏和从船艏延伸至船艉的船身段，其中船身段为传统船只的单体船线型，而船艏则包括两个并列设置的船艏部，两船艏部的末端间隔有一定距离，然后向船身段方向延伸时逐渐接近并连接，且它们之间的底部形状也从两只船只的形状逐渐过渡为单体船线型，并最终与船身段的底部形状相吻合。通过该种形状的设置，可以在高速航行时减小船舶的进流角，也减小了单个船艏部的傅氏数，从而减小了船舶航行的阻力，有效提高了船舶的航速和降低其所需的能耗。另外，两船艏部的底部相对侧处安装气泡减阻装置，这是因为经过船艏部之后的纵流段会具有较大的阻力，容易在船体中心线处形成急流，进而产生较大的摩擦阻力与黏压阻力，导致其影响船舶航速的提高；为此，在相应位置设置气泡减阻装置，通过大量微气泡的产生而形成纵流区域，以使急流可以顺畅地经过该区域，从而极大地减小急流带来的阻力，保证船舶航行的顺畅性和高航速、低能耗。该船舶船体型式结构通过双体船的船艏和单体船的船身，并结合气泡减阻技术，既可以有效提高船舶的航速并极大地降低所需的能耗，同时又具有单体船型舱容大、湿表面积小等优点。

具体实施方式
一种船舶船体型式结构，包括两个并列设置的船艏部1，两船艏部之间留有间隙，两船艏部向船舶中部延伸并相连接，且两船艏部连接端底部与船体基线所在平面所围的空间，从船艏向船舶中部方向逐渐减少并过渡为单体船底部线型。
所述的船舶船体型式结构，两船艏部1的底部相对侧处分别安装有产生气泡的气泡减阻装置2；且两船艏部1沿船舶中线方向的不同位置分别设置有气泡减阻装置2。
如图1-5所示，P为船体基线，船舶的船体包括两个船艏部1的船艏，和由船艏延伸至船艉的船身段3，两船艏部之间设置气泡减阻装置2，这些气泡减阻装置产生大量的气泡4。
两船艏部的末端间隔有一定距离，然后向船身段方向延伸时逐渐接近并连接，且它们之间的底部形状也从两只船只的形状逐渐过渡为单体船线型，并最终与船身段的底部形状相吻合。通过该种形状的设置，可以在高速航行时减小船舶的进流角，也减小了单个船艏部的傅氏数，从而减小了船舶航行的阻力，有效提高了船舶的航速和降低其所需的能耗。另外，两船艏部的底部相对侧处安装气泡减阻装置，这是因为经过船艏部之后的纵流段会具有较大的阻力，容易在船体中心线处形成急流，进而产生较大的摩擦阻力与黏压阻力，导致其影响船舶航速的提高；为此，在相应位置设置气泡减阻装置，通过大量微气泡的产生而形成纵流区域，以使急流可以顺畅地经过该区域，从而极大地减小急流带来的阻力，保证船舶航行的顺畅性和高航速、低能耗。该船舶船体型式结构通过双体船的船艏和单体船的船身，并结合气泡减阻技术，既可以有效提高船舶的航速并极大地降低所需的能耗，同时又具有单体船型舱容大、湿表面积小等优点。
