COMBINED PROPELLER BUSHING FOR TILTROTOR AIRCRAFT WITH ECCENTRIC MECHANISM Russian patent published in 2024 - IPC B64C11/06 B64C27/59 

FIELD: aviation.

SUBSTANCE: invention is related in particular to the designs of propellers of rotary-wing aircraft. The combined propeller hub of a tiltrotor aircraft with an eccentric mechanism consists of a crosspiece of propeller blades, a cup, propeller blades, a drive shaft, a thrust for changing the angle of attack of the blade, a control disk, a base, a drive shaft housing, a nacelle housing and a fairing. The eccentric mechanism includes a guide eccentric, a thrust eccentric, an automatic release mechanism for emergency eccentrics, a drive gear, a driven gear, an eccentric control rod, a servo drive, a compensating lever, and a stand.

EFFECT: mechanism is designed with the ability to individually control the propeller blades while simultaneously changing the propeller pitch depending on the flight mode of the tiltrotor aircraft.
