STEP-OVER BLADE-PITCH CONTROL SYSTEM

摘要

A pitch control system for blades on a rotor of an aircraft has a gimballing rotor hub and a plurality of step-over arms connected to the hub and capable of pivoting relative to the hub about a pivot axis. Each of a plurality of pitch links connects one of the step-over arms to a flight control system for pivoting the connected step-over arm about the pivot axis and relative to the hub in response to inputs from the control system. Each of a plurality of step-over links connects one of the step-over arms to one of the blades for rotating the associated blade about the pitch axis in response to pivoting of the associated step-over arm.
