Taking the references of the high lift-to-drag ratio vehicle aerodynamic shape design experiences,aimed at the aerodynamic performance requirements of the reenter vehicle,a blended lifting body aerodynamic shape with high lift-to-drag ratio is investigated to fit the vari-ous requirements of the reentry vehicle,and to quest a balance between the aerodynamic perform-ance of the traditional wing/body shape and the high cubage efficiency of lifting body.The pro-phase research shows that it is an advisable method to develop the blended lifting body aerody-namic shape optimization method by building the blended lifting body model,researching the parameterization method for the blended lifting body aerodynamic shape,selecting the design var-iables and their range,researching the optimization algorithm,building the blended lifting body aerodynamic shape design and optimization tool.In this paper,the optimization process is pro-posed by integrating the geometry dimensions parameterization program,the automatic grid gen-eration technique and the fast aerodynamic numerical calculation program based on Euler equa-tions.A fast aerodynamic shape optimization method is developed,and the optimization result is obtained and analyzed.A new blended lifting body shape with high lift-to-drag ratio is designed. The new shape provides an useful reference for the reentry vehicle design,and the optimization method has obvious advantages in computing speed and cost,and lays a technique foundation for the practical complex aerodynamic shape optimization.
