<p>FIELD: transport. ^ SUBSTANCE: invention relates to helicopter industry and is designed to control rotor thrust magnitude and direction. Swashplate comprises rotor mast 1, plate 2 and mechanism designed to control rotor thrust magnitude and direction. Said mast comprises shaft 3 running in roller bearing 5. Roller bearing inner race height exceeds that of outer race 7. Bal bearing 8 is used to incline aforesaid plate. Said plate comprises radial-thrust bearing housing inserts 11 and 12 clamped by rings 13. Crosswise and lengthwise tie rods 17 and 18 connected with helicopter control stick are pivoted to lower clamping ring. Thrust direction is varied by inclining rotor revolution plane due to cyclic variation of blade mounting angle depending upon azimuthal position of blades. ^ EFFECT: simplified design, higher reliability and lower weight of helicopter. ^ 4 cl, 2 dwg</p> |
