GAS TURBINE INTERMEDIATE STRUCTURE AND A GAS TURBINE ENGINE COMPRISING THE INTERMEDIATE STRUCTURE

摘要

The invention relates to a gas turbine intermediate structure ( 14 ) for being arranged between a first and a second gas turbine structure ( 8 and 9 ) in an axial direction ( 18 ) of a gas turbine ( 1 ). The intermediate structure ( 14 ) comprises an gas duct ( 5 c) arranged for guiding a gas flow from a gas duct ( 5 a) in the first structure ( 8 ) to a gas duct ( 5 b) in the second structure ( 9 ). An inlet ( 19 ) of the intermediate structure gas duct ( 5 c) is substantially displaced in a radial direction in relation to an outlet ( 20 ) of the intermediate structure gas duct ( 5 c). At least one guide vane ( 28,29 ) is arranged in the intermediate structure gas duct ( 5 c) for guiding the gas flow.
