Abstract

To improve the hydrodynamic performance and gliding economy of general dish-shaped underwater vehicles

a newly flying-wing dish-shaped autonomous underwater glider has been designed in this paper.The SST (Shear Stress Transmission) flow model in the computational fluid dynamic mechanics has been used to investigate the hydrodynamic characteristics including drag coefficient

lift coefficient

moment coefficient and lift drag ratio from 0 to 21°.A good agreement is between the experimental results and the numerical results

and flying-wing dish-shaped autonomous underwater glider has more excellent hydrodynamic performance and gliding economy.In addition

the six-degree-of freedom dynamics and kinematics equations of motion has been presented based on the multi-body dynamics with considering the vary velocities of moving sliders and the pump system quality to simulate typical gliding movement characteristics.The simulation results illustrate that the flying-wing dish-shaped autonomous underwater glider has certain stability and possibility of underwater movement.
