FIELD: aircraft engineering.
SUBSTANCE: invention relates to the field of aviation, in particular to the propeller designs. Rotary blade rotary support (30) comprises rotatable bracket (36) for radially mounting on the hub of the screw and pivotable about pivot axis (Z), and blade support (38). Holder (38) comprises socket (40) for mounting the blade leg, and at least one arm (34a, 34b) which is laterally disposed relative to the pivot axis and on which weight (32) forming the counterweight is mounted. In this case, the shoulder and load have a common geometric shape of the spherical arch.
EFFECT: weight of the structure is reduced.
