Abstract
Rotary apparatus () for a gas turbine engine () comprises a rotor assembly () and first and second stator assemblies () mounted coaxially with respect to each other. Each vane () has a leading edge and a trailing edge. The stator assemblies () are circumferentially translatable relative to each other between a first condition in which each of the vanes () of the second stator assembly () is substantially aerodynamically aligned with a respective one of the vanes () of the first stator assembly (), and a second condition in which the vanes () of the first and second stator assemblies () are out of aerodynamic alignment with each other. In the first condition, at least a part of each vane () of the second stator assembly () extends beyond the trailing edge of the respective vane () of the first stator assembly ().
