The invention provides a bow structure of a polar region transport ship, which is characterized in that an included angle A between a middle longitudinal section line of a bow of the ship bow and a designed waterline is 28.5-31.5 degrees, and a tangential angle B of the designed waterline of the bow at a quarter of the ship width is 36.5-37.5 degrees; the length of the design waterline is L; the water inlet angles a, b, c and d are respectively 55.0 degrees to 58.5 degrees, 40.3 degrees to 43.5 degrees, 36.0 degrees to 39.0 degrees and 36.33 degrees to 34.5 degrees; waterline angles e, f, g and h are respectively 41.5 degrees to 42.0 degrees, 27.5 degrees to 28.0 degrees, 24.0 degrees to 25.0 degrees and 20.0 degrees to 21.0 degrees; and the horizontal distance l between the lowest point of the bottom of the bow and the bow part of the bow is 20%-25% of the length of the polar region transportation ship. The bow structure provided by the invention can greatly reduce ice crushing resistance and open water resistance and reduce emission.

    本发明提供一种极地运输船艏部结构,船艏的艏部的中纵剖线与设计水线之间的夹角A为28.5°~31.5°,所述艏部在四分之一船宽处的设计水线切向角B为36.5°~37.5°;所述设计水线的长度为L;入水角a、b、c、d分别为55.0°~58.5°、40.3°~43.5°、36.0°~39.0°、36.33°~34.5°;水线角e、f、g、h分别为41.5°~42.0°、27.5°~28.0°、24.0°~25.0°、20.0°~21.0°;所述船艏的底部最低点与所述船艏的艏部之间的水平距离l为所述极地运输船长的20%~25%。本发明提供的船艏部结构可以大大减少碎冰阻力与敞水阻力,减少排放。
