Generalizations of some known results on the best, best linear and best one-sided approximations by trigonometric polynomials of the classes of 2π -periodic functions presented in the form of convolutions to the case of set-valued functions are obtained

In this paper we consider the problem of optimization of approximate integration of setvalued functions from the class defined by given majorant of their moduli of continuity, using values of the functions at n fixed or free points of their domain. We consider the cases of exact information and information with error.

Tha paper focuses on the problems of unmanned cruciform winged glider dynamics and control in autonomous flight conditions, and studies the wing aspect ratio effect on its flight performance. The winged glider control structure in the longitudinal and lateral axes is proposed. We carried out a comparative analysis of the ballistic flight ranges of models of different configurations, as well as the flight ranges of models of different configurations in the operating conditions of the control system of the proposed structure. As a result, the structure of the unmanned winged glider targeting system is proposed. The targeting system in the longitudinal axis, unlike the samples used in currently operating models, consists of two subsystems responsible for the unmanned winged glider best range gliding at the first flight phase and the direct aimpoint guidance at the second, i.e. final, flight stage
