IDEA #1UW02M Support and locking device for gas turbine nozzles

Abstract of EP1057975 A support and locking device for nozzles of a high-pressure stage in gas turbines comprises a plurality of groups (12) of stator vanes (13), which are associated with a plurality of outer sealing plates (11), for connection of the groups (12) to the outer liner of the combustion chamber, and are associated with a plurality of inner sealing plates (41), for connection of the groups (12) to the inner liner of the combustion chamber. Each of the groups (12) of stator vanes (13) is locked by an inner ring (14), and the ring (14) has a first series of outer holes (29) to reinforce this locking, and a second series, of inner, through holes (28), which are provided in an inner extension (34) of the ring (14) and are used to secure the ring (14) itself to the structure of the gas turbine. https://app.acclaimip.com/pdf/BlzFANREO0TVXMVlMUQ7SL7wEplviS-by0uKRwc/EP1057975B1
