航渡中反潜直升机的配置 总被引:2,自引:0,他引:2
水面舰艇编队航渡时,针对潜艇威胁,通常利用反潜直升机隐蔽、迅速的优势,将其配置在某一区域实施警戒,以达到对潜防御的目的。本文基于潜艇的威胁方向,分别对编队前方、侧翼以及综合前方和侧翼,探讨了反潜直升机警戒线的配置方法。在确定反潜直升机使用吊放声呐搜索方法的基础上,采用自同步思想,对反潜直升机警戒线的配置参数给出了定量描述。得出的结论实用、可行,为制定对潜防御方案提供了参考依据。 相似文献

基于作战行动航母编队兵力配置 总被引:3,自引:0,他引:3
科学合理的兵力配置是航母编队作战的前提和基础,影响航母编队兵力配置的因素很多,本文从作战行动的角度研究航母编队兵力配置问题。航母编队基本作战样式可分为对空作战、对海作战、对潜作战和对岸作战4种,基于4种基本作战样式分析了作战行动因素对航母编队兵力配置的影响与约束,并提出相应的原则与思路,有助于进一步完善航母编队兵力配置理论。 相似文献

Microbiologically influenced corrosion is a global problem especially materials used in marine engineering. In that respect,inhibitors are widely used to control fouling and corrosion in marine systems. Most techniques used in inhibitor production are expensive and considered hazardous to the ecosystem. Therefore, scientists are motivated to explore natsural and green products as potent corrosion inhibitors especially in nano size. In this study, antibacterial and anticorrosive properties of green silver nanoparticles(AgNPs) were studied through weight loss, electrochemical characterization, and surface analysis techniques. The corrosion of copper(Cu) in artificial seawater(ASW), Halomonas variabilis(H. variabilis) NOSK, and H. variabilis + AgNPs was monitored using electrochemical measurements like open circuit potential(OCP), electrochemical impedance spectroscopy(EIS), and potentiodynamic polarization curves. AgNPs showed excellent antibacterial activity against pathogenic microorganisms. Electrochemical studies demonstrate a noticeable decrease in OCP and current density in ASW containing H. variabilis +AgNPs compared to both ASW and ASW inoculated with bacterium, which confirmed the decrease of corrosion rate of copper.Furthermore, the obtained voltammograms show that the silver nanoparticles were adsorbed on the copper electrode surface from the corrosion solution. Thus, the results prove that the novel idea of green silver nanoparticles acts as an anticorrosive film in the marine environment. 相似文献

The parametric rolling of modern containerships is emerging as a serious problem, to the extent that its effects warrant a
study into its prevention. In light of this, two methods for reduction of parametric rolling are proposed and examined by
physical model experiments. The first is a sponson attached to the side of a ship, the purpose being to decrease the rate
of change of the rollrestoring moment. The second is an antirolling tank to increase roll damping. By conducting free-running
model experiments for a 6600-TEU post-Panamax container ship with sponsons under typical parametric rolling conditions, it
was found that the sponsons could decrease the magnitude of parametric rolling. The antirolling tank could prevent parametric
rolling completely in certain conditions, even in severe head seas. Using the damping coefficients from experimentally derived
data of a model ship with an antiroll tank, a numerical simulation was established. The numerical model was then compared
with the free-running model experiments. The results indicated that the numerical model could qualitatively verify the experimental
results. Finally, an attempt to optimise the size of an antirolling tank for preventing parametric rolling for the subject
post-Panamax container ship in the North Pacific Ocean is presented. 相似文献

采用流体分析软件Fluent,对典型船舶密闭舱室双层底进行二氧化碳气体保护焊接作业时的局部通风风流流场、有害气体CO2及CO浓度场分布进行数值模拟分析,确定有害气体扩散的数学模型。通过设置组分源项的方法利用组分输运方程得出在一定通风量的情况下CO2及CO气体的浓度分布规律,并与实测数据作对比,结果基本一致,由此可根据不同通风条件下确定焊接作业危险区域,为防止CO2集聚和CO中毒采取有效措施提供理论依据。 相似文献
