Abstract. Using the method of local variations, the process of constructing the aerodynamic configuration, based on optimizing its shape according to the aerodynamic quality criterion K, is considered. The shape of a delta wing with dimensionless length L ≡ 1 and span b = 1 was taken as the initial configuration in the optimization calculation. The shape and dimensions of internal geometric constraints are taken as the initial data. The volume of the body under study is not fixed. The optimal configuration that realizes the maximum aerodynamic quality has been determined; its properties have been studied. In the additionnal calculation, a prototype geometrically similar to the X-34 project, including the plan form and dimensions of the power plant, was taken as the initial data. The shape of the fuselage and the wing setting angle providing the maximum aerodynamic quality have been determined. An assessment of the aerodynamic quality of the resulting optimal shape shows its compliance with the required conditions.
