FIELD: aircraft engineering.SUBSTANCE: helicopter comprises fuselage with crew cab and engines, rotor with pitch adjuster and device to equalise reactive torque developed by rotor. Rotor hub runs in bearings on inclined hollow shaft. Said shaft is articulated by at least three rods with airframe and coupled with helicopter control mechanism. The shaft spinning the rotor is arranged inside said inclined hollow axle and incorporates two cardan joints of equal angular velocities, their kinematic axes being located nearby the plane of cardan joint of links with inclined shaft and airframe. Said inclined shaft can have the lever arranged in horizontal plane and articulated with airframe while rotor pitch variator has independent drive.EFFECT: higher reliability and safety, lower production and operation costs.2 cl, 2 dwg |
