FIELD: aeronautical engineering.
SUBSTANCE: aircraft lifting propeller has drive for synchronous turn of blades at free motion along drive shaft and rotating unit with rods mounted in it according to number of lifting propeller blades. Rods are articulated with levers. Blade synchronous turn mechanism is moved along drive shaft by means of hydraulic cylinder rod which is articulated with lug mounted in blade synchronous turn mechanism body.
EFFECT: enhanced reliability.
