摘要：A turbine section of a gas turbine engine is provided. The turbine section is annular about a longitudinal axis and includes first turbine with a first inlet and a first outlet; a second turbine with a second inlet and a second outlet; an inter-turbine duct extending from the first outlet to the second inlet and configured to direct an air flow from the first turbine to the second turbine; and a first guide vane disposed within the inter-turbine duct.

主权项：1. A turbine section of a gas turbine engine, the turbine section being annular about a longitudinal axis, the turbine section comprising: a first turbine with a first inlet and a first outlet; a second turbine with a second inlet and a second outlet; an inter-turbine duct extending from the first outlet to the second inlet and configured to direct an air flow from the first turbine to the second turbine; and a first guide vane disposed within the inter-turbine duct, wherein the inter-turbine duct is defined by a shroud extending between the first outlet and the second inlet and a hub extending between the first outlet and the second inlet, wherein the shroud and the hub are separated in a radial direction at a first distance, the first guide vane being spaced from the shroud in the radial direction at less than 50% of the first distance.
