Development and Experiments of the Passive Buoyancy Balance System for Sea-Whale 2000 AUV

The Sea-Whale 2000 Autonomous Underwater Vehicle (Sea-Whale 2000 AUV), developed by the Shenyang Institute of Automation, CAS, is an instrument platform designed to glide to depths of 2000 meters for the observation of environmental parameters of deep sea environment, which endurance can reach 1500 kilometers at the speed of 0.5m/s. In order to ensure that the platform can keep neutral buoyancy under different depth and reduce power consumption as much as possible, we design a set of passive buoyancy balance system. Through the bench and sea experiment, the passive buoyancy balance system can reliable applied to the Sea-Whale 2000 AUV system.
