Abstract
A variable vane actuation mechanism is comprised of a first drive vane arm and a second drive vane arm for driving a first variable vane array and a second variable vane array, respectively, of a stator vane section of a gas turbine engine. The first drive vane arm and second drive vane arm are connected to each other at a first end by a linkage. The first drive vane arm and second drive vane arm are connected at a second end to a first drive vane and a second drive vane, respectively, of the first and second variable vane arrays. The first drive vane arm and second drive vane arm respond in unison to a single actuation source connected to one of the first drive vane arm and second drive vane arm.
