Assembly for sealing an annular gap between an inner structure and an outer structure

A nacelle system for an aircraft propulsion system, comprising:

• a nacelle system component;
• an inner structure located in an aperture of the nacelle system component;
• and
• a seal assembly configured to seal a gap between the inner structure and the nacelle system component, the seal assembly including a seal land and a seal element;
• the seal land including a seal land mount and a seal land tube connected to the inner structure by the seal land mount;
• the seal land mount extending along a path from the inner structure to the seal land tube, wherein a length of the path is at least two times greater than a shortest distance from the inner structure to the seal land tube;
• and
• the seal element attached to the nacelle system component, the seal element circumscribing and sealingly engaged with the seal land tube, and the seal element comprising a polymer material.

A nacelle system for an aircraft propulsion system, comprising:

• a component;
• an inner structure within an opening of the component;
• and
• a seal assembly configured to seal a gap between the inner structure and the component, the seal assembly including a seal land, a polymer seal element and a non-polymer seal element;
• the seal land circumscribing and mounted to the inner structure, and the seal land configured to provide a restrictive heat conduction path from the inner structure to an outer surface of the seal land;
• the polymer seal element and the non-polymer seal element attached to the component at a common location;
• the polymer seal element circumscribing and sealingly engaged with the outer surface of the seal land;
• and
• the non-polymer seal element circumscribing and sealingly engaged with the seal land.
