The article discusses the possibility of using the manufactured device for servicing the front landing gear of the Mi-24 helicopter with a decrease in labor costs for preparatory work.

The article deals with the problem of preparing flight personnel for actions in complicated conditions the occurrence of helicopter icing, their impact on flight safety and measures aimed at preventing the occurrence of these phenomena.

In this article the of results of trim calculations are examined, the assessment of a helicopter – type unmanned aerial vehicle stiffness and controllability is realized, autorotation capability is evaluated, examples of maneuvers calculating are given.

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.
