Abstract

A software that accurately predicts submarine manoeuvring behaviour is essential for hull, sail and control surfaces design. In this context, the availability of a reliable 6-DOF parametric, modular, and robust model is highly advantageous at early design-stage. The here presented mathematical model is based on strip theory for calculating the linear forces on the bare hull, combined with non-linear cross-flow drag forces. The contribution of control surfaces and the sail are evaluated using a formulation derived from experiments and literature data, allowing to consider the specific geometry of the exposed surfaces and the hull sections on which they are mounted, thus including all mutual interaction effects between the various components, such as the body-wing and wing-body. In this first part of work a comparison between the results of the manoeuvring code and experimental data or other data available in literature is presented, demonstrating satisfactory reliability and robustness with a view to estimating stability and controllability.

6自由度潜艇机动性预测代码。第1部分：开发和验证

一个能够准确预测潜艇操纵行为的软件对于船体、船帆和控制面设计至关重要。在这种情况下，可靠的6自由度参数化、模块化和鲁棒模型的可用性在早期设计阶段是非常有利的。本文提出的数学模型是基于条带理论计算裸露船体上的线性力，并结合非线性横流阻力。控制面和风帆的贡献是使用从实验和文献数据中得出的公式来评估的，允许考虑暴露表面的特定几何形状和它们所安装的船体部分，从而包括各种组件之间的所有相互作用效应，例如体-翼和翼-体。在第一部分工作中，将操纵代码的结果与实验数据或文献中提供的其他数据进行比较，显示出令人满意的可靠性和鲁棒性，以估计稳定性和可控性。
