鋼鐵巨輪要想在海面上前行,離不開螺旋槳為其提供。而船隻越大,所需要的螺旋槳就越大。為了在造船技術上有所突破,世界各國都重視更大規格的螺旋槳的研發。最近,中國造出了世界最大螺旋槳,它足足有4層樓高,重達400多噸,連航母都不配用,因為它比美國航母還要大2倍。本期就讓我們一起了解一下世界最大的螺旋槳。

在過去很長一段時間裡,世界上最先進的造船技術被西方和日本所壟斷。除了從國外進口大型船隻外,中國還需要聘請相關技術人員。為了擺脫對他國的依賴和潛在的制裁危害,中國決心自主發展造船技術。不過,中國想建造一艘真正屬於自己的大型船隻,必須首先研發製造大型螺旋槳。

建造一艘大型船隻需要大量的工作,即使是最細小的螺絲螺母,也需要大量的時間和人力,更何況是作為推動船隻前行的重要裝置的螺旋槳。比方說,一艘美國的10萬噸級航空母艦會安裝四個巨型螺旋槳,每個螺旋槳重達200多噸。如果想要製造10萬噸級甚至更大的船隻,僅僅200噸的螺旋槳都顯得力不從心。

除了螺旋槳的大小和重量以外,螺旋槳還涉及很多問題,例如如何設計螺旋槳扇葉的曲面弧度以實現最大的推進效率,這涉及流體力學知識。以及如何在保持螺旋槳強度的同時減輕重量,提高船隻前進的效率,這與材料的力學有關。此外,螺旋槳需要選用擁有耐腐蝕性和可加工性強的銅合金,這些都對中國的科研人員提出了極大的挑戰。

中國的科研團隊和工人們經歷了一年多艱苦的研究,最終在中國鎮江中船瓦錫蘭螺旋槳公司,屬於中國自己的世界最大的國產螺旋槳成功面世。這個螺旋槳由4個葉片組成,每個葉片直徑為12.5米,總重量約為480噸,是美國航空母艦使用的螺旋槳規格的兩倍,可以說是世界上最大的螺旋槳。

如今中國造船業快速發展,為未來的大型船舶建設提供了強有力的支持。這與數千名中國科學家日夜的艱苦研究密不可分。此外中國航空母艦的發展也對更大更好的螺旋槳提出了更高的要求。因此,中國今天能夠製造世界上最大的螺旋槳,未來還會進一步磨礪自己,把這一技術提升到更高的水平。
