Features
As well as the helicopter, an autogyro possesses the bearing screw for creation of carrying power, however the autogyro screw freely rotates under the influence of aerodynamic forces in the autorotation mode. The free bearing screw of an autogyro is possible the simplified scheme, without change of the general step. He creates only carrying power and in flight is inclined against a stream, like the fixed wing with a positive angle of attack back. At the helicopter, on the contrary, the screw is inclined towards the movement since creates the driving bearing screw lifting and propulsive forces at the same time. Except the bearing rotor, the autogyro possesses also the pulling or pushing mid-flight screw (propeller) which reports to an autogyro horizontal speed.
The intermediate position between an autogyro and plane occupies a rotary-wing aircraft which has the connected drive of the bearing screw from the engine and differs from an autogyro in what can use not only the mode of autorotation, but also the mode of helicopter flight. The rotor system of a rotary-wing aircraft operates on big speeds in the way, similar to an autogyro (in the autorotation mode), providing only the carrying power, but not draft. It is possible to tell that the rotary-wing aircraft combines qualities of an autogyro and the helicopter.
The first autogyros with a rotor without automatic machine of a distortion coped with the help of aerodynamic wheels therefore vertical landing turned out uncontrollable and usually was considered as the extraordinary mode.
Modern control systems of an inclination of the plane of the bearing screw (the plug possesses two degrees of freedom) allow to make landing without run as controllability of the device does not depend on its air speed. For realization of vertical start (jumping up) preliminary promotion of the bearing screw with a zero step on the earth (from the engine), with the subsequent shutdown of its drive and installation of a working step of the screw is possible.
