IMPROVED FIREPROOF DEVICE INTENDED FOR BEING PLACED BETWEEN END OF PYLON OF SUSPENSION OF TURBOMACHINE OF AIRCRAFT AND CASING OF MENTIONED TURBOMACHINE SEPARATING INTER-FLOW COMPARTMENT Russian patent published in 2022 - IPC B64D27/26 B64D45/00 F02C7/25 F02C7/28 F16J15/02 F16J15/06 

FIELD: aviation.

SUBSTANCE: invention relates to engines of an aircraft. Fireproof device (50) is proposed, intended for being placed between a pylon of suspension (9) of a two-contour turbomachine of an aircraft and connecting casing (30) provided for this turbomachine. The connecting casing is intended for coupling of upstream ring (10) limiting part of inter-flow compartment (8a) with bracket (22) passing radially through a secondary flow of the turbomachine. Device (50) is made in the form of a mono-block, and it contains two contact edges (52a, 52b). At the same time, first edge (52a) has C-shaped section, second edge (52b) is carried by a support part through a connection zone.

EFFECT: prevention of reaching by the fire of an upstream zone of a suspension pylon located nearly; protection of the pylon from the fire, ease of manufacture and embedding of a protection device into a protection zone.
