Study on Geometrical Parameter and Flow Mechanism for C-wing Aerodynamic Configuration

In this paper,the geometrical parameter and flow mechanism for C-wing aerodynamic configuration based on F-4 wing has been investigated by numerical method.The geometrical parameter of wingtip for C-wing has been chose according to least induced drag,the preliminary rule of geometrical parameter and flow mechanism for C-wing is discovered,the effect of wingtip′s vertical and horizontal surface on aerodynamic characteristics is provided.The investigation shows,which C-wing is provided with high aerodynamic efficiency and is adopted for large airplane design.
