Abstract

A system is provided for a nacelle (22) of an aircraft propulsion system (20). This system includes a tubular outer structure (102), a tubular inner structure (114) and a seal assembly (98). The tubular inner structure (114) projects through a bore of the tubular outer structure (102). The seal assembly (98) is configured to close an end of an annulus between the tubular outer structure (102) and the tubular inner structure (114). The seal assembly (98) includes a seal land (144) and a seal element ((146),(148)). The seal land (144) includes a seal land mount (162) that circumscribes and is attached to the tubular inner structure (114). The seal land mount (162) is configured with a v-shaped sectional geometry. The seal element ((146),(148)) is attached to the tubular outer structure (102). The seal element ((146),(148)) circumscribes and is sealingly engaged with the seal land (144). The seal element ((146),(148)) may be configured from or otherwise includes a polymer material.
