SEAL FOR A TURBOJET ENGINE PYLON AND NACELLE, AND TURBOJET ENGINE PYLON-NACELLE ASSEMBLY INCORPORATING SUCH A SEAL

摘要

A fire-resistant seal for a propulsion assembly which includes a pylon, an O-duct type nacelle of a turbojet engine. The nacelle includes an inner fixed nacelle structure and a combustion gas ejection primary nozzle, and the fire-resistant seal is placed in an annular sector defined by the inner fixed nacelle and the gas ejection primary nozzle. In particular, the fire-resistant seal includes a plurality of baffles, and the plurality of baffles are longitudinally disposed so as not to interfere each other during a longitudinal translational movement of the inner fixed nacelle structure relative to the combustion gas ejection primary nozzle.
