The concept of one planform-controllable waverider is proposed to extend the flexibility of the osculating waverider design. The universal geometry relations between the design and planform parameters are deducted, and employing the non-uniform rational B-spline in representing the design curve to aid design, the article builds the method of the double swept waverider generation in which the blunt area and swept area are controllable. The design variables are extracted to customize the planform of the waverider. The rapid aerodynamic assessment including viscous effect, validated with the CFD technique, is applied to analyze the influence of the design variables for waverider properties. The research shows that the hypersonic high L/D property of the waverider remains with the modified planform and lays the solid foundation to design the novel waverider configurations.
