Abstract

1406098 Turbomachine shrouding B B C BROWN BOVERI & CO Ltd 8 Nov 1972 10 Nov 1971] 51616/72 Heading F1T To enable the clearance a between the tips of turbine or like rotor blades 2 and surrounding stator shroud segments 7 to be adjusted the mounting lugs 8 of the latter engage circumferential grooves 6 in stator blade carriers 3 via packing shims 12, 12'. The angles α, α' of the shroud surface and rotor blade tip respectively are the same.
