Abstract:
A stator vane assembly for a turbomachine comprising a plurality of circumferentially arranged stator vanes and a plurality of circumferentially arranged load bearing struts,each stator vane having a leading edge, a trailing edge and a chord length, each strut having a leading edge, a trailing edge, a pressure surface, a suction surface and a chord length, the chord length of the struts being greater than the chord length of the stator vanes,the stator vanes being arranged in groups between adjacent pairs of struts, each group of stator vanes comprising a plurality of stator vanes, the circumferential spacing between adjacent stator vanes in a group being substantially the same,the circumferential spacing between adjacent struts being substantially the same,the circumferential spacing between the suction surface of one of the struts of an adjacent pair of struts and an adjacent stator vane being less than the circumferential spacing between adjacent stator vanes in the group and the circumferential spacing between the pressure surface of the other of the struts of the adjacent pair of struts and an adjacent stator vane being greater than the circumferential spacing between adjacent stator vanes in the group to equalise aerodynamic loading of the stator vanes and to reduce the aerodynamic losses of the struts.
