NON-CONTACT SEAL ASSEMBLY FOR ROTATIONAL EQUIPMENT

摘要

Assemblies are provided for rotational equipment. One of these assemblies includes a first bladed rotor assembly (106), a second bladed rotor assembly (108), a stator vane assembly (50), a stator structure (52) and a seal assembly (58). The second bladed rotor assembly (108) includes a rotor disk structure (92). The stator vane assembly (50) is axially between the first (106) and the second (108) bladed rotor assemblies. The stator structure (52) is mated with and radially within the stator vane assembly (50). The seal assembly (58) is configured for sealing a gap between the stator structure (52) and the rotor disk structure (92), wherein the seal assembly (58) includes a non-contact seal (208).
