Abstract
An inter-turbine duct is positioned between a high pressure turbine and a low pressure turbine of a gas turbine engine. The inter-turbine duct includes an inner annular wall and an outer annular wall spaced apart from the inner annular wall along a radial direction to define an annular flow passage. The inter-turbine duct includes a plurality of circumferentially spaced vanes positioned within the flow passage and at least one temperature probe is positioned upstream of the vanes at a circumferential location that is between thirty and seventy percent of a circumferential distance between the leading edges of adjacent vanes.
Claims20
A gas turbine engine comprising:
- a high pressure turbine;
- a low pressure turbine positioned downstream of the high pressure turbine;
- and an inter-turbine duct positioned between the high pressure turbine and the low pressure turbine, the inter-turbine duct defining an axial direction, a radial direction, and a circumferential direction, the inter-turbine duct comprising:
- an inner annular wall;
- an outer annular wall spaced apart from the inner annular wall along the radial direction to define an annular flow passage;
- a plurality of circumferentially spaced vanes positioned within the flow passage and extending between the inner annular wall and the outer annular wall, each of the vanes defining a leading edge, a circumferential distance being defined between the leading edges of adjacent vanes;
- and a probe positioned within the flow passage and extending substantially along the radial direction, the probe being positioned upstream from the vanes along the axial direction and at a circumferential location that is between thirty and seventy percent of the circumferential distance between the leading edges of adjacent vanes.
An inlet duct defining an axial direction, a radial direction, and a circumferential direction, the inlet duct comprising:
- an inner annular wall;
- an outer annular wall spaced apart from the inner annular wall to define an annular flow passage;
- a plurality of cumferentially spaced vanes positioned within the flow passage and extending between the inner annular wall and the outer annular wall, each of the vanes defining a leading edge and a circumferential distance being defined between adjacent leading edges;
- and a probe positioned within the flow passage and extending substantially along the radial direction, the probe being positioned upstream from the vanes along the axial direction and at a circumferential location that is between thirty and seventy percent of the circumferential distance between the leading edges of adjacent vanes.
