FAN BLADE RETENTION AND VARIABLE PITCH SYSTEM

摘要

A system (10) for providing variable pitch to a rotor blade (16) of an aircraft engine includes a rotatable hub (34); at least one blade mounted on the rotatable hub; a gear mechanism operably connected to the rotatable hub; a timing ring (46) rotatably and operably connected to the gear mechanism; and a pitch arm (74) operably connecting the timing ring and the at least one blade mounted on the rotatable hub. In the operation of the system, the gear mechanism facilitates the rotation of the timing ring to vary the pitch of the at least one blade mounted on the rotatable hub.
