Abstract

A method of reducing the fluid flow effects of one or more flow modifiers (19) in a passage (16), the method comprising: providing a plurality of aerofoil structures (15) in the passage (16), wherein the geometry of each aerofoil structure (15) is initially substantially the same; and shortening the trailing edge (18) of one or more selected aerofoil structures (17) in a chordwise direction and over at least a spanwise portion of the one or more selected aerofoil structures such that, when in use, the direction of the fluid flow (20a, 20e) in the vicinity of the one or more selected aerofoil structures is altered and the fluid flow effects of the one or more flow modifiers (19) in the passage are reduced.
