Abstract:
1. A system for a turbo machine, the system comprising: a rotating vane and a static vane, the rotating vane and the static vane positioned between an outer casing and an inner casing, the rotating vane and the static vane each having a root region, a tip region, and a pitch region between the tip region and the root region; a first channel having a first end proximate to the tip region of the static vane positioned to capture tip leakage of an operative fluid of the turbo machine from the rotating vane and a second end proximate to the pitch region of the static vane to redirect the tip leakage radially inward from near the tip region to the pitch region; and a second channel having a first end proximate to the root region of the static vane positioned to capture root leakage of the operative fluid of the turbo machine from the rotating vane and a second end proximate to the pitch region of the static vane to redirect the root leakage radially outward from near the root region to the pitch region, wherein one of the first channel or the second channel is disposed entirely within the static vane.
