Hydrodynamic Performance Analysis of Fly-Wing Underwater Glider Flaps Based on Overlapped Grid Technology

For the Fly-wing underwater glider, the influence of flaps on the hydrodynamic characteristics of the Fly-wing underwater glider is obtained by means of computational fluid dynamics and overlapped grid method. Taking the wing body distance, the flap height and the chord length of the flaps as the design parameters, the influence of different design parameters on the lifting effect of the Fly-wing underwater glider is obtained, and the lift-to-drag ratio of the Fly-wing underwater glider flaps is also studied analysied.
