摘要:

续航力与水平速度均是水下滑翔器的重要性能指标。采用单位重量滑翔器、单位水平速度所耗功率作为滑翔效率的评价指标，以一新型扁平型水下滑翔器为研究对象，利用 CFD 计算结合模型试验验证的方法获取了所需的流体动力系数，然后进行了滑翔运动分析及垂直面滑翔运动仿真计算，得到了最优滑翔运动参数。 建立的滑翔性能计算方法对扁平型水下滑翔器水动力性能设计及滑翔运动参数优化有着重要的应用价值。

Abstract:

Both endurance and horizontal velocity are important specifications for underwater gliders. In this paper，the power consumption per unit weight glider and unit horizontal velocity is used as the criterion of gliding efficiency. Taking a new flat underwater glider as the studying object，hydrodynamic forces coefficient is acquired by the method of CFD calculation in combination with model test verification，and gliding motion analysis and the vertical plane gliding motion simulation are carried out to obtain the optimized gliding parameters of a new flat underwater glider. The gliding performance calculation method established in this paper has important application value for the hydrodynamic performance design and gliding parameters optimization of flat underwater gliders.
