Independent Velocity Measurement of Small Underwater High-Speed Moving Body Based on External Turbine

Abstract:

Combining with rotational speed measurement methods and underwater environment particularity, an independent velocity measurement scheme applicable to small underwater high-speed moving body was proposed in this paper. The structural design of the measurement device was designed and signal process method was improved, and the relationship between turbine rotational speed and speed of the body was obtained by FLUNET dynamics simulation and water tunnel experiments. Finally, the simulation and experimental results were analyzed. The results show that this method is effective and feasible within a certain range of accuracy.
