A turbine stator vane assembly (23C) comprises a plurality of circumferentially arranged struts (60) and a plurality of circumferentially arranged stator vanes (62). Each stator vane (62) has a leading edge (68), a trailing edge (70) and a chord length (CL). Each strut (60) has a leading edge (76), a trailing edge (78), a chord length (CS), a pressure surface (80) and a suction surface (82). The chord length (CS) of the struts (60) is greater than the chord length (CL) of the stator vanes (62). The stator vanes (62) are arranged in groups (G1, G2) between adjacent pairs of struts (60) and each group (G1, G2) of stator vanes (62) comprises a plurality of stator vanes (62). The circumferential spacing between adjacent struts (60) is substantially the same and each stator vane (62) in a group (G1, G2) of stator vanes (62) has a different chord (CL) length to the other stator vanes (62) in that group (G1, G2) of stator vanes (62). |
