A fluid flow machine stator vane assembly comprises an inner ring 1 and an outer ring 2 linked by a plurality of vanes 3A, the rings and vanes forming an integral structure. A further plurality of separate vanes 3B also link the inner and outer rings. The inner ends of vanes 3B locate in slots (5) (Fig 4) formed in the inner ring 1 while the outer ends of vanes 3B extend through slots 6 in ring 2 and are acted upon by springs 14 retained by a segmented ring 7 surrounding ring 2. The segments 8 of ring 7 are secured to studs (10) (Fig. 2 & 3) extending outwardly from vanes 3A. Vanes 3A may be metal while vanes 3B may be composite or ceramic and are replaceable if damaged. <IMAGE>
