FIELD: aircraft engineering.
SUBSTANCE: invention relates to the field of aviation, in particular rotor blade control systems. The swashplate of a multi-rotor aircraft with a rigid attachment of blades consists of a base to which an internal rack is bolted, on which a supporting rotating cylinder is mounted with the help of support bearings and a thrust bearing. On the outside of the cylinder, a driven gear is fixed, to which energy is supplied from the engine through the drive shaft with the drive gear. A separate drive is designed to control the rotation stop of the carrier rotating cylinder. Inside the rack there is a threaded collective pitch control shaft, on the lower part of which there is a worm gear and a worm shaft from an electric motor with a gearbox. When the threaded shaft rotates, the threaded part raises or lowers the L-shaped collective pitch control slider. The rotating cage, through ball bearings and rods, also transmits the control action to the blades, which are attached to the supporting rotating cylinder through the support and thrust bearings, between which the blade rotation mechanism is located.
EFFECT: invention provides possibility to perform vertical take-off and landing and high-speed horizontal cruising flight of aircraft.
