Researching on mathematical computation and experimental bench design of high-pressure blowing system

Abstract

Abstract Utilized in sinking and surfacing of Autonomous Underwater Vehicle(AUV), the high-pressure blowing system(HPBS)had played an important role in maneuvering pilot of AUV and must be investigated thoroughly, by which the reserve buoyancy can be controlled. Because of the costliness of experiment on the real ship, an experimental bench of HPBS had been proposed and designed. After mathematical computations of sinking and surfacing processes of AUV, the pressure vessel prototype and it critical physical parameters selection were accomplished, which were used as ballast tank and sea environmental tank of the HPBS experimental bench. Based on those, the blueprint of the total experimental bench had been drawn and the working course of HPBS had been demonstrated.
