The invention belongs to the technical field of ship molded line design of polar icebreaking ships, and particularly relates to a comprehensive operation icebreaking ship bow with navigation performance and multi-aspect icebreaking capacity. On the basis of the V-shaped ship bow profile with the optimal icebreaking capacity, the cross section graph is designed, the outward floating angle is greatly increased, and the icebreaking capacity of the icebreaker bow is further improved. On the premise of ensuring that the icebreaking bow is excellent in icebreaking capacity, the longitudinal section line is optimized, a small longitudinal section line angle and a stem dip angle are adopted, and the ice removing capacity of the icebreaker bow is improved. In the molded line design process, the principle that the performance is not reduced during navigation in the open water area is considered, and the comprehensive performance of the ice breaking capacity, the ice removing capacity and the open water area performance is considered at the same time. The comprehensive operation icebreaking ship bow is suitable for multiple tasks and multiple routes, the utilization efficiency can be maximized, and the economic cost for manufacturing multiple single-function icebreaking ships is controlled to a certain extent.
本发明属于极地破冰船舶型线设计技术领域,具体涉及一种兼顾航行性能和多方面破冰能力的综合性作业破冰船艏。本发明以采取破冰能力最优的V型船艏轮廓为基础,设计了横剖线图,大大增大了外飘角,进一步提升了破冰船艏的破冰能力。本发明在保证破冰艏在破冰能力优越的水平上,优化了纵剖线,采取了较小的纵剖线角和艏柱倾角,增加了破冰船艏的清冰能力。在型线设计的过程中,本发明兼顾敞水域航行时性能不降低的原则,同时兼顾了破冰能力、清冰能力和敞水域性能的综合性能。本发明适用于多任务多航线,可以最大化利用效率,一定程度上控制了在多条单一功能破冰船制造上的经济成本。
