Research on the Hydrodynamic Characteristic of Conformal Semi-Ring Wing Configuration

To meet the demand for flying both in air and water, a conformal semi-ring wing configuration is proposed in the design of air-water crossing vehicle. Aiming at the demand of high-velocity hydrodynamic characteristics, a multiphase flow model is introduced to the numerical simulations. The pressure distribution of the air-water crossing vehicle at different velocities and attack angles is studied and the shape and location of the cavitation are obtained. The results provide support for the subsequent optimization and experimental verification of air-water crossing vehicle.
