Abstract. The paper is devoted to the review of controlled motion of the unmanned aerial vehicle (UAV) with vertical takeoff and landing, the convertiplane type, with three tilt rotors. The UAV is equipped with a swept wing, the calculation of aerodynamic parameters of which has been carried out in the software program XFLR5, taking into consideration the weight and size requirements. There have been determined the lift and resistance coefficients of the UAV depending on the angle of attack on the basis of the vortex method. There has been done the analysis of the influence of wing profile on the calculated aerodynamic characteristics. There also has been realized the synthesis of the traction energy-efficient options of the drive propellers that reduce power consumption, increasing the accuracy of the automatic control system.
