Abstract

A turbine engine stator stage (100) comprises a plurality of vanes (120) with each of the plurality of vanes having a camber angle. The plurality of vanes is arranged in a plurality of groups (170) with each group comprising a pre-determined sequence of vanes. The ordering of vanes within each group is determined by the camber of the individual vanes. This results in an arrangement of vanes within the stator stage (100) which can modify the flow characteristics of the air entering the stator stage to reduce the circumferential pressure variation in the flow region immediately downstream of the stator stage.
