The article considers the results of optimization of the main rotor and determines the flight characteristics of a UAV with an optimized main rotor. To achieve this goal, a mathematical model of the helicopter's hovering main rotor was created, which allows you to find the propeller thrust and power consumption depending on the blade profile, blade shape in plan, geometric twist and fill factor.

The article considers an approach to modeling the flight dynamics of rotorcraft using SimMechanics tools of the Matlab/Simulink environment. The proposed approach involves using a simulation model of the helicopter's carrier system in order to determine the magnitude of forces and moments created by the main and tail propellers, for their subsequent implementation in a mathematical model of flight dynamics.
