Research on turning maneuverability of submerged glider of the wave glider

Abstract

Turning Maneuverability is an important hydrodynamic performance of the wave glider, which can realize the position keeping, path tracking and steering obstacle avoidance in a reliable way. The influences on the maneuverability of the relevant parameters of the rudder are analyzed by using the Computational Fluid Dynamic (CFD) method in this paper. Through the analysis, the conclusions that the optimal rudder area ratio with 0.15 and the aspect ratio with 0.8 are drawn. Furthermore, the position and profile of the rudder are also analyzed. To verify the validation of the work, sea trial data of the “Black Pearl” wave glider is adopted and analyzed. The result shows that the simulation analysis of the turning maneuverability of submerged glider is correct. And the conclusions have great significance for improving the turning maneuverability of the wave glider and the parameter design of the submerged glider engineering prototype from the perspective of the engineering application.
