Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] see figure 1 , which is a structural schematic diagram of the engine nacelle sealing fireproof assembly of the present invention. The engine nacelle sealing fireproof assembly of the present invention is composed of a rubber profile 1 , a spoon-shaped pressing plate 4 and a fastener 3 . Among them, the sealing end of the rubber profile is a cylindrical sealing body with a tadpole-shaped cross section. The free end 2 of the spoon-shaped pressing plate is bent to match the surface of the sealing end of the rubber profile. The fixed end of the spoon-shaped pressing plate is connected to the tail end of the rubber profile and the short The cabin structure 5 is connected and fixed.

[0016] Engine nacelle sealing and fireproof components are mainly used in special parts of aircraft such as engine nacelle structures that have high requirements for fireproo...

Abstract

The invention belongs to a fireproof sealing technology for an engine nacelle and relates to a fireproof sealing assembly for the engine nacelle. The fireproof sealing assembly for the engine nacelle comprises a rubber profile, a spoon-shaped pressing plate and a fastener, wherein the sealed end of the rubber profile is provided with a cylindrical sealed body, and the section of the rubber profile is tadpole-shaped; the free end of the spoon-shaped pressing plate is bent and is matched with the surface of the sealed end of the rubber profile; the fixed end of the spoon-shaped pressing plate is connected and fixed with the tail end of the rubber profile and a nacelle structural part through the fastener. According to the fireproof sealing assembly for the engine nacelle, the surface of the rubber profile is protected by the spoon-shaped part of the spoon-shaped pressing plate for fixedly installing the fireproof sealing rubber profile and is prevented from directly contacting a flame, friction between the surface of the rubber profile and an adjacent movement structure is effectively reduced, the replacement and reassembly frequency of the rubber profile is reduced, the cost is reduced, and the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the engine nacelle sealing and fireproofing technology, and relates to an engine nacelle sealing and fireproofing assembly. Background technique [0002] According to the airworthiness clauses of airworthiness standards for transport category aircraft, the engine cover and nacelle skin of the aircraft must meet the following requirements: It shall be designed and constructed so that the fire occurring in any fire zone cannot enter through the opening or burn through the outer skin Any other fire zone or area of ​​increased hazard. Therefore, the material selection and component structure design of the engine nacelle must be able to contain and isolate the flame, prevent fuel or air from being supplied to the existing fire area, so as to ensure the effective operation of the components of the engine control system, and make it possible to safely shut down the engine or APU and safe feathering. A fire in an aircraft power plant...
