摘要 关于水下航行器结构设计优化问题,混合驱动水下航行器(HUG)是一种新型水下航行器,实现了自治式水下航行器(AUV)与水下滑翔机(AUG)结构和功能的集成,具有航速大、航程长、机动性好等特点。混合驱动水下航行器所受水阻力与机动性是其水平推进模式(AUV模式)下的重要性能指标。针对混合驱动水下航行器的要求与结构特点,采用计算流体力学方法,分析了航行器在AUV模式下的航行水阻力和机动性。研究表明,混合驱动水下航行器在集成AUV与AUG功能优势的同时,在AUV运行模式下,航行阻力将增大约30%,航行机动性降低约15~25%。结果为混合驱动水下航行器的外形设计提供了依据。 Hybrid-driven underwater vehicle (HUG) is a new type of autonomous underwater vehicle. It is an in- tegration of conventional autonomous underwater vehicle (AUV) and autonomous underwater glider (AUG) in the structure and function. It can autonomously cruise in the water in the AUV mode and follow sawtooth trajectory in the AUG mode. The distinguished features include high speed, long cruising range, and good maneuverability. Maneu- verability and the hydrodynamic drag on the vehicle are two important factors to evaluate performance of the vehicle under the AUV mode. In this paper, vehicle maneuverability and the hydrodynamic drag in the AUV mode were in- vestigated using computational fluid dynamic method. Results show that the integration of AUV and AUG may require a sacrifice of maneuverability and causing an increase in the drag, which are decreases of 15% - 25% in the maneu- verability and an increase of 30% in the drag for the presented hybrid-driven underwater vehicle.
