Abstract
A labyrinth seal that may include a first leg positioned about a high-pressure side of the dovetail tab, a second leg positioned about a low-pressure side of the dovetail tab, and a labyrinth chamber positioned between the first leg and the second leg. High-pressure fluid passing through the gap about the first leg expands within the labyrinth chamber so as to limit an amount of the high-pressure fluid that passes beyond the second leg.
