Abstract: A seal land for a gas turbine engine can include a seal body that can extend between a leading edge portion, a trailing edge portion, a radially outer surface and a radially inner surface. A notch can extend at least partially through the seal body between the radially outer surface and the radially inner surface.

Abstract: A mid-turbine frame (MTF) system for a gas turbine engine is disclosed. The MTF includes an inner case, an outer case and a fairing sandwiched between the inner and outer cases. The fairing includes an inner ring spaced apart from and coupled to an outer ring by a plurality of hollow struts. The hollow struts accommodate support rods that connect the inner case to the outer case. Further, the hollow struts act as turning vanes for turning the flow of gases passing from a high pressure turbine (HPT) to a low pressure turbine (LPT) for purposes of providing the correct incidence angle to the first vane of the LPT. The outer ring of the fairing includes a plurality of bosses which receive attachment pins that pass through the outer case for correctly locating the fairing with respect to the outer case and for permitting radial expansion in contraction of the fairing.
