1. An assembly comprising a plurality of stator vanes,
wherein the assembly is centered on a longitudinal axis and the plurality of stator vanes is distributed circumferentially around the longitudinal axis, each stator vane of the plurality of stator vanes extending radially with respect to the longitudinal axis, the longitudinal axis defining a main direction of the assembly,
wherein each stator vane of the plurality of stator vanes has a first chord and a second chord, the first chord being taken at a root of the stator vane and the second chord being taken at a tip of the stator vane, the root of the stator vane being closer to the longitudinal axis than the tip of the stator vane,
wherein each stator vane of the plurality of stator vanes has an adjacent stator vane that is positioned adjacent to the stator vane in a circumferential direction around the longitudinal axis,
wherein, for each stator vane of the plurality of stator vanes, the first chord of the stator vane does not overlap the first chord of the adjacent stator vane in the main direction, and the second chord of the stator vane overlaps the second chord of the adjacent stator vane in the main direction.
