Zusammenfassung:	A hydrostatic seal assembly (100) configured to be disposed between relatively rotatable components includes a base (107). The seal also includes a shoe (108) operatively coupled to the base (107). The seal further includes a secondary seal (122) disposed proximate an axially forward end of the shoe (108), the secondary seal (122) extending radially from a radially inner end (124) to a radially outer end (126) to define a radial distance of the secondary seal (122), the secondary seal (122) having an axially forward face. The seal yet further includes a structural component (120, 130, 132) located adjacent to the axially forward face of the secondary seal (122) and extending radially inwardly to cover at least half of the radial distance of the secondary seal (122).
