Abstract:
A vane for use in a gas turbine engine has an airfoil extending between a leading edge and a trailing edge, a radially outer platform and a radially inner platform. A rib is on one of the radially inner and radially outer platforms, and is adjacent the trailing edge of the airfoil. A mid-turbine frame is also disclosed.
Abstract:
A vane has an airfoil extending between a radially outer platform and a radially inner platform. At least one of the platforms has nominally radially thinner portions, and a pad defining a radially thicker portion. The pad has a radial thickness that is greater than a thickness of the nominal radially thinner portions. The pad surrounds an outer periphery of the airfoil on a side of the radially outer platform. The pad has a varying radial thickness. A mid-turbine frame and a gas turbine engine are also disclosed.
Abstract:
An airfoil extends between radially inner and radially outer platforms. The airfoil extends between a leading edge and a trailing edge, and merges into facing surfaces of the radially inner and outer platforms. A variable fillet merges a facing surface of one of the radially inner and outer platforms into a wall of the airfoil. The variable fillet has a length extending away from a surface of the airfoil and a height extending away from the facing surface of at least one of the radially inner and outer platforms outwardly on to the airfoil. The variable fillet has a greater length at one of the leading edge and the trailing edge. A spaced portion has a shorter length at locations spaced from at least one of the leading and trailing edges. A mid-turbine frame and a gas turbine engine are also disclosed.

Abstract:
An airfoil (200), comprising an airfoil body and an internal cavity (210) within the airfoil body. The internal cavity (210) may comprise an outer edge (212) comprising a first outer scallop (213) and a second outer scallop (213), an inner edge (211) opposite the outer edge (212), the inner edge (211) comprising a first inner scallop (213) and a second inner scallop (213), a leading edge (208) spanning between the outer edge (212) and the inner edge (211), and a trailing edge (209) spanning between the outer edge (212) and the inner edge (211) and opposite the leading edge (208). Between the outer edge (212), the inner edge (211), the leading edge (208), and the trailing edge (209), the internal cavity may comprise eight columns of pedestals (221...228) disposed axially relative to one another and axially between the leading edge (208) and the trailing edge (209).
Abstract:
A turbine vane includes an inner platform (72) and an outer platform (74) joined together by an airfoil (70). The airfoil (70) has a leading edge (80) and a trailing edge (82) joined together by a pressure side (84) and a suction side (86) disposed opposite the pressure side (84). The inner platform (72) defines a plurality of first inner cooling holes (96) and a plurality of second inner cooling holes (98) that are fluidly connected to an inner cooling passage (94). The plurality of first inner cooling holes (96) are disposed proximate the leading edge (80) and extend towards the suction side (86) and the plurality of second inner cooling holes (98) are disposed proximate the trailing edge (82) and the suction side (86) and extend towards the leading edge (80).

A variable fillet merges a facing surface of one of the radially inner and outer platforms into a wall of the airfoil.
