RESUMO

The method of profiling of elements of a high-speed flying vehicle airframe and power plant nozzle is presented. The lift at the cruising flight is chosen as the objective function, which is maximized under external dimensions constraints and isoperimetric condition on the pitch moment. The direct optimization method is used, which combines the flow modeling within the framework of the Euler equations and the Newton minimization algorithm. The results of elementwise optimization and complex optimization which strengthens the positive effects of integration are compared. Analysis of total aerodynamic loads on the optimal configurations is performed.
