Wings design and numerical simulation of aerodynamic characteristics of trans-media glider
In response to the current problem of slow underwater speed and long transition time to the predetermined operation area when deploying on shore or ship,this paper designs a rectangular breakable wing using subsonic symmetric airfoil based on its original wing.By breaking the wings,the underwater glider is compatible with both underwater and aeri-al gliding functions,providing the foundation for trans-media gliding;A numerical calculation model for a trans-media glider using the wing was constructed using computational fluid dynamics methods,and numerical simulation experiments were conducted on the aerodynamic characteristics of the glider under the influence of the wing.The experimental results indicate that.Within the scope of this study,a trans-media glider with a subsonic symmetric airfoil and a breakable wing is used for horizontal flight with a stall speed of no less than 90.5 m/s during aerial gliding.It also has good lift drag ratio and pitch characteristics,and good static stability under main operating conditions.It can start aerial gliding at an initial speed of 0.8 Ma,effectively reducing the time required for the glider to transition to the predetermined operating area.
