Problems solved by technology

These connection forms have high requirements on the processing and assembly of parts, the process is difficult, the shock absorption and compression resistance are poor, and the clamps in the form of multi-lobe structures with grooves are heavy. Mass use has a great impact on the weight of the aircraft, which is not conducive to aircraft lose weight

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] One end of the left metal conduit 4 is welded with the left flange 6, and one end of the right metal conduit 5 is welded with the right flange 7. The left flange 6 and the right flange 7 are connected together with an accessory or an aircraft fixed structure by bolts. There is a certain compensation gap when the other ends of the left metal conduit 4 and the right metal conduit 5 are connected, and the flexible heat-resistant rubber hose 3 with a circular cross section presses the rolling bosses at both ends of the left metal conduit 4 and the right metal conduit 5 tightly together , the grounding gasket 1 is lapped on the left metal conduit 4 and the right metal conduit 5, the section of the ring clamp 2 is almost circular, and the two ring clamps 2 are fixed on the left metal conduit 4 and the right metal conduit 5. On the outside of the wave boss, fix the ...

Abstract

The invention belongs to the field of aerotechnics, relates to a connection structure for an air flue pipe, in particular to the air flue pipe connection structure with the two ends rigidly connected and the middle flexibly connected on an airplane. The connection structure for the air flue pipe on the airplane is characterized by comprising a bonding spacer (1), annular hoops (2), a flexible heat-resistant rubber pipe (3) with the annular cross section, a left metal guide pipe (4) and a right metal guide pipe (5); the metal guide pipes are connected with the flexible heat-resistant rubber pipe with the annular cross section, a compensation clearance is reserved between the metal guide pipes, mounting is convenient, the coaxiality of the pipe is easy to adjust, and the damping compensation action on metal is achieved.

Description

technical field [0001] The invention belongs to the field of aviation technology, and relates to a connection structure for air ducts, in particular to an air duct connection structure on an aircraft with rigid connections at both ends and flexible connections at the middle. Background technique [0002] In the connection pipeline of aircraft ram cold air, due to the particularity of the interface of heat exchangers or accessories, the air duct pipe usually adopts a square structure, and is connected and fixed with finished products and aircraft structural parts through flanges. Some are clamps in the form of grooved multi-lobe structures. These connection forms have high requirements on the processing and assembly of parts, the process is difficult, the shock absorption and compression resistance are poor, and the clamps in the form of multi-lobe structures with grooves are heavy. Mass use has a great impact on the weight of the aircraft, which is not conducive to aircraft ...
