Description

一种船体 技术领域
本发明涉及一种船体， 特别是一种适于冰区航行的船体。
背景技术
船舶在冰区航行， 阻力较之一般水域明显要大很多， 为了用于冰区航行， 需满足芬 兰-瑞典冰级规范的要求， 其主机所需的推进功率较非冰区航行所需的推进功率要大很 多； 吨位越高的船舶， 其所需推进功率也大得越多。 例如对于 50000载重吨级的油轮， 常规非冰区航行所需的推进功率约在 10000-llOOOkW之间， 而满足芬兰-瑞典冰级规范 所需的推进功率则约 20000kW。而一般情况下，船舶需在非冰区航行的时间远大于其需 在冰区航行的时间， 这样使得满足芬兰 -瑞典冰级规范要求的船舶在大部分的非冰区航 行的时间内经济性很差。 发明内容
本发明的目的在于克服上述缺点， 提供一种减小冰区航行阻力， 既能满足芬兰-瑞 典冰级规范的要求， 又能降低船舶主机的推进功率、 提高船舶航行的经济性的船体。
本发明的船体， 其最小吃水水线与最大吃水水线之间的所有水线的左、 右两侧四分 之一宽处的进流角的大小介于 20度到 26度之间。
由于船舶在冰区航行时， 其前方有破冰船为其开路， 因此， 其航行的主要阻力来自 于破冰船开路后形成的碎冰， 船舶向前航行时， 这些碎冰主要作用于船体的左、 右两侧 水线的四分之一宽至二分之一宽的位置， 那么只要减小船体左、 右两侧水线四分之一宽 处的进流角的大小就能够很好的降低船体所受的阻力，从而降低船舶主机所需的推进功 率。 然而进流角也不能太小， 如果太小， 则其对船体的排水量影响较大， 因而将进流角 控制在 20度至 26度之间， 这样既保证了船体的排水量， 又极大的降低了船舶满足芬兰 -瑞典规范所需的推进功率。经模拟实验表明为了满足芬兰-瑞典规范采用本发明所述船 体的船舶在冰区航行时， 其主机推进功率约为采用一般船体的船舶主机推进功率的 55%—60%。 附图说明
图 1 为船体侧面的示意图；
图 2为船体水线进流角的示意图。
