摘　　要：续航力与水平速度均是水下滑翔器的重要性能指标。文章以单位重量滑翔器、单位水平速度所耗功率作为滑翔效率的评价指标,给出了混合驱动水下滑翔器滑翔参数最优解寻求的数学方法。文中以一典型滑翔器为例,针对其多种工况(无桨、桨不转、桨随动和桨工作),利用CFD预报了所需的流体动力系数,然后分别给出了它们最优的滑翔参数。研究结果表明,该评价指标物理意义明确,优化方法简单,对工程设计具有很高的参考价值。Both endurance and horizontal velocity are important specifications of a underwater glider. Taking the power consumption per unit weight and per unit horizontal velocity of a glider as the criterion of a glider efficiency was proposed in this paper. The mathematic approach of optimized solution under the criterion was also introduced, the optimized parameters of a hybrid underwater glider under different conditions（without propeller, with fixed propeller, with propellers driven by free up-stream or electromotor） were shown as an example, where needed hydrodynamic forces were given by CFD. The results demonstrates that the criterion has definite physical meaning, the optimization method is a simple and effective tool in engineering designing of a glider.
