Abstract
A modular variable vane assembly includes an airfoil, an inner case, and an outer case. The airfoil extends between a first end and a second end along an axis. The airfoil has a connector that extends from the first end and a pivot member that extends from the second end. The inner case defines a pivot opening that is arranged to receive the pivot member. The outer case defines a first opening that extends from a first outer case surface towards a second outer case surface along the axis. The first opening is arranged to receive the connector.
