“蛟龙”号载人潜水器关键技术研究与自主创新

“蛟龙”号载人潜水器是中国自行设计、自主集成并独立完成海试的具有国际上最大下潜深度——7000m的尖端产品，2011年在东北太平洋中国多金属结核合同区西区成功进行了5000米级海上试验与应用，取得了一系列技术和应用的成果。从技术角度阐述了“蛟龙”号载人潜水器的研制过程，重点围绕在研制过程中所遇到的关键技术问题以及在解决这些问题过程中的自主创新情况。

Key Technologies and Self Innovation of “JIAOLONG” Manned Submersible

＂JIAOLONG＂ manned submersible is a top technology product selfdesigned, selfassembled and independently tested at sea by China, which has the world＇s deepest submergence of 7000m. ＂JIAOLONG＂ successfully completed the 5000m sea trial and operation in the west part of the Northeast Pacific China ploymetallic nodule area, and obtained a series of technical and practical achievements. This paper elaborates the research process of ＂JIAOLONG＂ from the technical point of view, and focuses on the key technological problems during the research process and the self innovation fruits for solving those problems.
