The technique of integrated optimization of aerospace vehicle parameters and trajectories by the united criterion of target efficiency is described. The technique uses a decomposition of a multidisciplinary problem into single-disciplinary subtasks of flight dynamics and control, aerodynamics, propulsion and structures. The sensitivity functions of the target criterion with respect to design parameters are objectively calculated on the basis of solution of the trajectory optimization problem using the Pontryagin maximum principle. The technique has the special advantages in the optimization of multiregime high-speed vehicles, when an influence of layout parameters on the target efficiency is essentially depend on flight conditions. Some applications of the technique for the integrated optimization of space launchers are demonstrated. The qualitatively new optimal solutions in comparison with traditional ones are revealed due to the proposed approach.
