The helicopter rotary wing aircraft unit, which are necessary for flight lift and thrust generated by one or more rotors (propellers) driven by an engine or multiple engines. Almost every time the main rotor of the helicopter is equipped with a swash, which moves the center of pressure of the propeller for flight control (with the exception of some schemes with 3 or more rotors).
In the case of a single drive rotor, it is obligatory mechanism for damping its torque (often a tail rotor or fenestron, less ink-jet device, etc.), and in mnogolistovyh diagrams, torque usually kompensiruet the counter-rotation cores rotors. If the screw is driven in rotation by jet engines mounted on the blades, the torque is almost not noticeable and freely kompensiruet aerodynamic control surfaces. To unload the rotor at high speed, the helicopter can be equipped with a well-developed wing, to increase directional stability can in turn be used plumage.

If some time ago the author said that he would have to “reinvent the wheel”, he would take it as a joke. However, the skepticism has vanished after discovering a magazine with a model of “vetrohod”, made by Alexander Twins. The model had air and propellers sitting on the inclined shaft, and moved strictly against the wind under the action… of the wind!
