Abstract

In the main flow passage of aero gas turbines, the channel connecting the high-pressure stage and low-pressure stage is generally called inter-turbine duct (ITD). The inter-turbine duct mainly serves as a flow passage, which is formed by the casing and hub, and in some occasions, the duct, together with guide vanes, also serves as a supporter and pathway of accessory pipelines. In geometry, the inter-turbine duct is an annular pipe with its two ends having different diameters; the end connecting to the high-pressure turbine is its inlet, and the other end, which connects to the low-pressure turbine, is its outlet.
