A fluid flow machine comprises an array of vanes () which are supported at their ends by inner and outer support structures. The ends of the vanes are received in slots, with resilient materialdisposed between the vaneand the wall of the slot. A restraint elementis mounted in a recessof the support structureand is engaged by a notchin the vaneto restrict axial displacement of the vane. Consequently, vibration of the vane in directions perpendicular to the lengthwise direction of the vane are damped by the elastomeric materialbut bodily axial displacement of the vaneis prevented by the restraint elements
