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 the results of mathematical modeling of the flywheel motion of a single rotor blade, obtaining integral characteristics of a single rotor, calculation features of the carrier system with coaxial propellers, modeling the approach of helicopter blades of a coaxial scheme.
The article deals with the examples of the most frequently used computer software for tackling five problems in navigational calculations for helicopter flight.
