METHOD AND APPARATUS FOR TURBOMACHINE ACTIVE CLEARANCE CONTROL

摘要

An apparatus for providing active clearance control between blade tips and seals in a turbomachine comprising: a first stator carrier segment (30), with stator seals (24) centripetally disposed on it; a second stator carrier segment (32) located along a same circumference as the first stator carrier segment (30), also with stator sea ls (24) centripetally disposed on it; a shell (10) that adjustably houses the first stator carrier segment (30) and the second carrier segment (32); at least one displacement apparatus (34) in operable communication with at least one stator carrier segment (12) and configured to position the at least one stator carrier segment (12) to provi de active clearance control to the stator seals (24) disposed on the at least one stat or carrier segment (12).
