FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering, particularly, to propellers of aircraft power plants. Propeller comprises two blades folded in the screw rotation plane, a bushing for installation on the drive shaft, one blade is connected to the bushing without possibility of rotation in the screw rotation plane. Second blade is made with possibility of rotation relative to the axis that does not coincide with the screw rotation axis, with the blade support in the retracted and working positions in the appropriate bearing surfaces of the bushing. Propeller comprises remote locks for fixation of the folded blade in the retracted and operating positions and at least one damping device for damping the impact of the folded blade on the propeller hub when moving it from the working position to the folded and in the reverse direction.
EFFECT: reliable fixation of foldable blade, improvement of aerodynamic resistance at cruise mode of vertical take-off and landing aircraft.
