This study establishes a method to overcome the choked-flow and flow-hysteresis problems of the Busemann biplane at offdesign conditions during its acceleration and deceleration processes. Two-dimensional analyses of Busemann-type biplanes have been addressed using the application of a computational fluid dynamics code in both inviscid and viscous flow modes. The effect of stagger on the aerodynamic characteristics of the Busemann biplane is validated. The biplane with the continuous stagger approach shows a lower drag coefficient during the acceleration process as compared with the baseline Busemann biplane and the diamond airfoil. The results also show that this strategy is efficient to reduce the choked-flow and flow-hysteresis problems for the biplane configuration at the offdesign condition.
