Title:
航空機系における可変形状ギャップのための封止システム
Document Type and Number:
Japanese Patent JP7204411
Kind Code:
B2
Abstract:
An apparatus comprising a housing (316), seal (318), and energy storing device (320). The housing (316) is coupled to a structure (308) in an exhaust system (300) of an aircraft (304). The structure (308) is positioned relative to a surface (306) within the exhaust system (300) such that a gap (310) is present between the surface (306) and structure (308). The seal (318) has an end (322) positioned in contact with the surface (306) to reduce a flow of exhaust through the gap (310) and is coupled to the housing (316) such that the seal (318) extends within the housing (316). The energy storing device (320) is coupled to the housing (316) and engaged with the seal (318) to allow the seal (318) to translate in a first direction relative to the housing (316) when the gap (310) increases and in a second direction opposite the first direction relative to the housing (316) when the gap (310) decreases such that the seal (318) continues to reduce the flow of exhaust through the gap (310) as the gap (310) changes in size.
