Abstract:
A vane assembly used for controlling a turning gas flow includes multiple vanes, each of which is bowed toward a pressure side of the vane at the root of the vane.
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:
A gas turbine engine (20) includes a compressor section (24), a combustor (56), and a turbine section (28). The combustor (56) has a radially outer surface that defines a diffuser chamber (112) radially outwardly of the combustor (56). The turbine section (28) has a high pressure turbine first stage blade (118) that has an outer tip, and a blade outer air seal (126) positioned radially outwardly of the outer tip. A tap (102) for tapping air has been compressed by the compressor (56) and is passed through a heat exchanger (104). The air downstream of the heat exchanger (104) passes through at least one pipe (120) and into a manifold (122) radially outward of the blade outer air seal (126), and then passes across the blade outer air seal (126) to cool the blade outer air seal (126).
Abstract:
A turbomachine (20) includes an annular flow path section (70a) between a plurality of radially extending stator vanes (66) and a plurality of radially extending rotor blades (68). At least a first portion (72a) of the flow path section (70a) has a circumferentially varying outer periphery which includes a recess (81) circumferentially alternating with axisymmetric surfaces.
