A new wing/body configuration of CAV, a powerless maneuverable hypersonic glide vehicle, is presented. The eonfignration of CAV is generated by conic lofting design method. The configuration of CAV is parameterized in terms of conic control points and shape parameters, which improves the efficiency of configuration design. The revised Newtonian Theory is applied to estimate the hypersonic aerodynamic characteristics. And then the trajectory of CAV is simulated and optimized aimed to maximizing the flight range. The results show that this CAV can satisfy hypersonic performance. The geometry parameterization of CAV is useful to configuration selection and worth to be investigated further.
