Inner diameter variable vane actuation mechanism

A variable vane actuation mechanism is comprised of a first drive vane arm (38A) and a second drive vane arm (38B) for driving a first variable vane array and a second variable vane array, respectively, of a stator vane section (10) of a gas turbine engine. The first drive vane arm (38A) and second drive vane arm (38B) are connected to each other at a first end by a linkage (36). The first drive vane arm (38A) and second drive vane arm (38B) are connected at a second end to a first drive vane (20A) and a second drive vane (20B), respectively, of the first and second variable vane arrays. The first drive vane arm (38A) and second drive vane arm (38B) respond in unison to a single actuation source (18) connected to one of the first drive vane arm (38A) and second drive vane arm (38B).
