Latest Patents

Niall Macdonald holds a patent for a labyrinth seal designed to impede leakage flow through a gap between static and moving parts in a turbomachine. The labyrinth seal features axially spaced and circumferentially extending sealing fins that are arranged in a series to effectively manage leakage flow. These fins project across the gap from at least one of the confronting parts, ensuring sealing proximity with the opposing part. Notably, the fins have a distal portion that is curved or inclined in the upstream direction of the leakage flow, which helps to deflect the leakage flow. The design allows for the creation of chambers that accommodate recirculating vortices produced by the deflected leakage flow.
