ABSTRACT:
A stator assembly 28 for a gas turbine engine 10 is disclosed. The stator assembly includes an inner stator structure 54 and an outer stator structure 52. A plurality of tensioned members 50 extend radially between the structures to stiffen the structures against deflection and to restrain the structures against relative movement. In one embodiment, the inner stator structure is an engine casing 54, the outer stator structure 42 is a fan casing, and the radially extending members are a plurality of guide vanes 50.
