Cylindrical or truncated ring for e.g. jet prop engine, has internal slots housing internal blades between discharge ends of channels and internal longitudinal edges of radial surfaces, where blades extend on axial length of ring sectors

Abstract: A ring for a turbomachine turbine wheel, comprising end-to-end ring sectors (118) and sealing means mounted between the ring sectors, the sealing means comprising internal and external lamellae housed in slots (158, 162) opposite the radial faces (156) facing the ring sectors, the ring sectors having channels (168) of air ejection opening on these radial faces, the slots ( 162) housing the inner lamellae extending substantially over the entire axial length of the ring sectors, between the outlets of the air ejection channels and the inner longitudinal edges (166) of these radial faces.
