Development and Experiments of the Buoyancy Adjusting System of Long-Range AUV

摘要

The Long-Range Autonomous Underwater Vehicle (LR-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. In order to ensure that the platform can keep neutral buoyancy under different depth and the security of surface communication, we design a set of buoyancy adjusting system. The buoyancy adjusting device consists of a hydraulic buoyancy-regulation system and a pneumatic buoyancy-compensation system. Through the test, the buoyancy adjusting system can reliable applied to the Long-Range2000 AUV system.
