[Abstract]:Hybrid driving underwater glider is a new type of underwater self-propelled vehicle which integrates the advantages of buoyancy gliding and propeller propulsion. As an autonomous underwater observation platform, it has great application prospect in both military and civilian fields. There are three working modes of hybrid driving underwater glider: buoyancy gliding working mode, power gliding working mode for fast maneuvering and high precision track requirement, power gliding working mode for long voyage and high concealment. Fixed deep navigation mode, used to obtain the parameters of the specific depth of the operation of the water layer. Based on the previous research results of the research group and the simple buoyancy driven underwater glider, a small deep-sea propulsion system is designed and developed in this paper, and the prototype of the hybrid drive underwater glider PETREL- 鈪，
