摘要

研究对象和目的。本研究旨在设计和制造一个用于各种船内推进器自推进试验的虚拟试验台。该试验台将用于测试水下物体的喷水设计。材料和方法。根据内部KSRC技术,对螺旋桨和定子叶片的几何形状进行分析评估,对在水道中运行的两排叶片系统的运行条件进行数值模拟。主要结果。内部水射流与水下物体船体的相互作用以前从未进行过研究。为了估计这种相互作用,决定用合适的船体模型进行自推进试验。这项工作包括设计和制造一个代表水下物体船体的虚拟试验台,并实现船体内喷水器的流体动力学测量。这项工作的另一个成果是设计和制造了一个四排船体推进装置。结论本工作中制造的虚拟试验台可进一步用于优化各种配置的船内喷水器。除了本文所述的配置外,设计、制造和在水道的初始部分应用组合式轮缘驱动推进电机也是可行的。

Dummy test rig design for in-hull propulsors of underwater objects
Object and purpose of research. This research was intended to design and manufacture a dummy test rig for self-propulsion testing of various in-hull propulsors. This test rig will be used to test waterjet designs for underwater objects. Materials and methods. Analytical assessments on geometry of propeller and stator blades, numerical simulation of operational condition for two-row blade system operating in the water duct as per in-house KSRC techniques. Main results. Interaction of internal waterjets with the hull of underwater object has never been studied before. To estimate this interaction, it was decided to perform self-propulsion tests with a suitable hull model. This work included design and manufacturing of a dummy test rig representing a hull of underwater object and enabling hydrodynamic measurements for an in-hull waterjet. Another result of this work was design and manufacturing of a four-row in-hull propulsion unit. Conclusion. The dummy test rig manufactured in this work could be further used to optimize in-hull waterjets of various configurations. Apart from the configuration described in this paper, it could also be feasible to design, manufacture and apply a combined rim-driven propulsion motor in the initial part of the water duct.
