摘　　要：当前,能在全海深(11000 m)范围内进行观察作业的载人潜水器代表了最前沿的国际深海载人技术。随着下潜深度的增加,如何大幅度提高下潜和上浮速度以确保海底作业时间已经成为潜水器设计中的关键问题。该文是系列研究的第一篇论文,主要解读刚刚完成挑战马里亚纳海沟壮举的由美国导演Cameron设计的"深海挑战者"潜水器的水动力性能,它采用鱼雷外形,实现了下潜上浮速度的大幅提升。该文研究了各外形参数对该深潜器本体阻力的影响,采用优化拉丁方法设计了深潜器本体阻力系数的计算方案,并采用二阶响应面方法,给出了深潜器本体阻力系数的估算公式。此研究结果可供我国今后研制全海深载人潜水器时参考。At present, the deep sea manned submersible which can be operated at full ocean depth with maximum depth of 11,000 meters represents the forefront of the international deep-sea technology of manned submersibles. With the increasing diving depth, how to increase significantly the descent and ascent rates to ensure the bottom time of operation has become a key problem. Currently for this purpose there are three types of deep sea manned submersibles are being developed internationally, using different hydrodynamic principles. This article is the first one of authors＇ research series. The hydrodynamic performance of the submersible DEEPSEA CHALLENGE, which was designed by film director James Cameron and has completed the challenge of the Mariana Trench dive, is studied. By adopting a torpedo shape, the DEEPSEA CHALLENGE has greatly increased its descent and ascent speeds. The effect of shape＇s traits on main hull resistance of DEEPSEA CHALLENGE is analyzed. Optimal Latin hypercube design method is used to draw up the calculation schemes and an empirical formula for main hull resistance coefficient is presented by way of second-order response surface methodology. The results of present research can provide a reference for designing deep manned submersible later on.
