Abstract: An assembly for a gas turbine engine includes a rotor formed by a drum and a hub. The drum has a generally conically shaped inner surface that defines a flow path along a first cavity. The hub is connected to the drum and has a conically shaped inner surface that defines a flow path along a second cavity.

Abstract: An example vane arm testing rig includes a base having a first attachment configured to receive a first end of a vane arm when the vane arm is in an engaged position, and a torque member having a second attachment configured to receive an opposing, second end of the vane arm when the vane arm is in the engaged position. The vane arm extends along a longitudinal axis from the first end to the second end. The first and second attachments are configured to rotate relative to each other about the axis. The first and second attachments are configured to move laterally relative to each other.
