Device and method for preventing leakage of air between multiple turbine components

摘要

A turbine (10) comprising a first turbine component (12) being of a first material having a first coefficient of thermal expansion. A second turbine component (18) being of a second material having a second coefficient of thermal expansion, said second turbine component adjacent said first turbine component. A space between said first and second turbine components. A seal assembly (28) sealing said space, wherein at least a portion (30) of said seal assembly has a coefficient of thermal expansion substantially similar to at least one of said first or second turbine components to thereby maintain a seal in said space during thermal expansion or contraction of said first and second turbine components.
