A compliant foil seal, comprising:
- a bottom foil configured to be located circumferentially around at least a portion of a rotor;
- and
- one or more upper foils configured to cooperate with a stator to position the bottom foil to compliantly face the rotor and be located between the stator and the rotor.
A compliant foil seal assembly, comprising:
- a plurality of compliant foil seals disposed end-to-end and configured to be located annularly around a rotor, each compliant foil seal comprising:
- a bottom foil configured to be located circumferentially around at least a portion of the rotor, and
- one or more upper foils configured to cooperate with a stator to position the bottom foil to compliantly face the rotor and be located between the stator and the rotor.
A rotary machine, comprising:
- a stator;
- a rotor rotatably received in the stator;
- and
- a plurality of compliant foil seals disposed end-to-end to be located annularly around the rotor, wherein each compliant foil seal comprises:
