Dynamic seal for a turbine engine

A seal (10) usable in a turbine engine for sealing a high pressure gas region (30) from a low pressure gas region (28). The seal (10) seals gaps between a rotatable body (12) and a stationary body (14) by creating forces opposing flow from the high pressure region (30) to the low pressure region (28...

Zusammenfassung:	A seal (10) usable in a turbine engine for sealing a high pressure gas region (30) from a low pressure gas region (28). The seal (10) seals gaps between a rotatable body (12) and a stationary body (14) by creating forces opposing flow from the high pressure region (30) to the low pressure region (28). During turbine engine operation, the seal (10) creates aerodynamic forces that substantially prevents leakage of gases from a high pressure region (30) to a low pressure region (28). The seal (10) may be formed from a plurality of blades (16) aligned in one or more rows and extending from a rotatable body (12) towards a stationary body (14) of the turbine engine to be in close proximity to the stationary body (14). The seal (10) may also include a plurality of blades (20) aligned in one or more rows and extending from the stationary body (14) towards the rotatable body (12) to be within close proximity of a surface of the rotatable body (12).
