英文摘要： The underwater glider is a new kind of autonomous underwater vehicle. It has many advantages such as a low energy cost, and a long endurance, a long operational range with its unique device. In this project, the hydrodynamic performances will be analyzed and the lifts, the drags and the moments at the different velocities and the different attack angles will be calculated using numerical method. As the new conceptions，the efficiency gliding and bionic propulsion will be applied on the underwater glider design. Besides of taking into account the resistance, the fixing angle of wings and guide line to enhance the gliding efficiency will be proposed according the transfer efficiency from the consumed work to the available work, so the gliding attitude will be optimized. According to the performance of fish swimming with tremendous propulsive efficiency, the bionic propulsion for the underwater glider is designed. The fluid structure of the bionic propulsion are analyzed. The internal relations between characteristic parameters of bionic propulsion and propulsive performance will be get. The free-running model test of demonstrator of the underwater glider with the high efficiency will be made, including model design and making, inner systems layout and model test.
