Mid turbine frame for gas turbine engine

摘要

A mid turbine frame (28) with an annular interturbine duct (110) may be assembled by placing an mid turbine frame inner case (34) of into the interturbine duct (110), inserting a plurality of mid turbine frame spokes (36) radially through respective hollow radial struts (118) of the interturbine duct (110) to be connected to the mid turbine frame inner case (34) to form a mid turbine frame spoke casing (32). A mid turbine frame outer case (30) is also connected to the spokes 36), to provide an assembled mid turbine frame (28).
