摘　　要：混合驱动水下滑翔机是兼有浮力驱动和螺旋桨驱动两种驱动模式的新型水下自航潜器。通过建立混合驱动水下滑翔机在3种驱动模式下纵垂面内定常运动的动力学模型,研究了不同驱动模式下攻角、速度、滑翔角之间的关系,对不同驱动模式下驱动系统的能耗进行分析比较。结果表明,在相同净排量和相同滑翔落差条件下,混合驱动模式单位航程能耗值大于纯滑翔模式,而净浮力为零时的水平直航模式下能耗最少,并通过水域试验进行了验证。根据所得结论,面向不同的任务、海况等可选择不同的驱动方式来节约电量,对混合驱动水下滑翔机的设计与应用有一定的指导意义。A hybrid underwater glider is an autonomous underwater vehicle containing two engines, buoyancy engine and propeller. The hybrid underwater glider vertical dynamics model under three different engine modes were established, and the relation among attack angle, gliding angle and velocity under different engines was researched. Besides, the energy consump- tion of the engine mechanism with different engines was analyzed. The result shows that in the condition of the same net buoy- ancy and gliding depth, the hybrid glider consumes more energy in unit range with hybrid engine than with buoyancy engine, and the hybrid underwater glider in straight and level flight with zero net buoyancy consumes the least energy, it was validated by water tests. According to the conclusion, for different tasks and sea states, different engine models can choose to save ener- gy, which provide guidance for the design and application of the hybrid underwater glider.
