Abstract

In the paper exact and approximation analytical expressions for calculation of the gas-dynamic jets parameters for gas-dynamic complex are obtained. The sizes of gas-dynamic complex for providing of the unmanned aerial vehicle takeoff and landing with help of these expressions be defined. In particular, the relationship between the aerodynamic characteristics of the unmanned aerial vehicle and braking distance in artificial airstream is obtained. The mathematical model of the unmanned aerial vehicle motion in artificial airstream is based on kinematics and flight dynamics equations. Peculiarity of this model is that it is used real function of velocity distribution in a transverse cross-section of axisymmetric flooded.
