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. The first stator assembly is upstream of the second stator assembly, and the second stator assembly is upstream of the rotor assembly. The rotor assembly comprises an annular array of rotor blades, and each stator assembly comprises an annular array of stator vanes. Each vane has a leading edge and a trailing edge. The stator assemblies are circumferentially translatable relative to each other between a first condition and a second condition. 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.
