Abstract

One of the crucial aspects of the conceptual design of a stepped planing hull is the prediction of its performance. To improve performance, the prediction of total resistance must become more accurate. In the field of research, both towing tank experiments and numerical analysis may be used to achieve this goal. In this study, experiments were conducted initially to investigate total resistance of a relatively high-speed craft without a transverse step. Later, numerical computations were carried out to validate the experimental results. After it was determined that the test results and CFD methods were in good agreement, the experimental method continued to investigate the resistance properties of the hull with four different configurations to evaluate the optimal longitudinal position of a single transverse step. The ideal longitudinal position of the single transverse step was evaluated based on a similar relatively high-speed hull with a velocity of up to beam Froude number (FrB) 2.56 in this study, focusing on the FrB range between 2.30 and 2.45.
高速飞行器纵向单横台阶最佳位置的研究
阶梯滑行船体概念设计的一个关键方面是对其性能的预测。为了提高性能,总阻力的预测必须更加准确。在研究领域,拖曳舱实验和数值分析都可以用来实现这一目标。在这项研究中,最初进行的实验是为了研究没有横向台阶的相对高速飞行器的总阻力。随后进行了数值计算,验证了实验结果。在确定测试结果与CFD方法一致后,实验方法继续研究四种不同配置的船体阻力特性,以评估单个横向台阶的最佳纵向位置。在本研究中,单个横向台阶的理想纵向位置是基于速度高达梁弗劳德数(FrB)2.56的类似相对高速船体进行评估的,重点是FrB范围在2.30至2.45之间。
