Abstract
The utility model provides a blocking plate for preventing bird strike. The blocking plate comprises a main body structure and a supporting structure for installation. The main body structure comprises an inner face plate close to one side of an airplane, an outer face plate parallel to the inner face plate, an aluminum honeycomb plate clamped between the inner face plate and the outer face plate and a sealing edge, wherein the inner face plate and the outer face plate are made of organic plates. When bird strike happens, the inner face plate and the outer face plate of the blocking plate for preventing bird strike can both absorb bird strike energy, and meanwhile the aluminum honeycomb plate can deform to buffer bird strike and further absorb energy. Thus, impact force caused by birds to the airplane can be buffered jointly by the inner face plate, the outer face plate and the aluminum honeycomb plate. Furthermore, the airplane is prevented from being broken through, bird meat is prevented from being shot into a cabin, a pilot is prevented from being injured or an airplane system is prevented from being damaged, and an airplane structure can meet the CCAR-25.571 clause.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
For realizing above-mentioned utility model object, the utility model provides a kind of lighter weight for plane nose and the strong anti-bird of crashproof ability to hit baffle plate (not label), in the present embodiment, described anti-bird is hit baffle plate and is arranged in nose radar cover region (not shown), is specifically arranged on airtight end FR frame.There is bird while hitting, anti-bird is hit baffle plate and can protect airtight end FR frame not breakdown, prevents that bird meat from injecting driving compartment and injuring chaufeur, destroy aircraft system.Certainly be different from the present embodiment, described anti-bird is hit other positions that baffle plate also can be arranged at aircraft to reach identical effect.
Refer to shown in Fig. 1 ~ Fig. 2, described anti-bird is hit baffle plate and comprises agent structure 1 and supporting construction 2, by being provided with supporting construction 2, being convenient to be fixed on aircraft, and can not destroying the agent structure 1 that anti-bird is hit baffle plate; Also be convenient to maintenance.
Described agent structure 1 comprise near the wainscot 11 of FR frame one side, and wainscot 11 be arranged in parallel and towards the outer panels 12 of radar one side, be located in aluminum honeycomb panel 13 and edge sealing (not shown) between described wainscot 11 and described outer panels 12.Described wainscot 11 is the organic board that quality is light, intensity is large with described outer panels 12, and described organic board is selected from kevlar fabric or the high-molecular polythene etc. that intensity is larger.In the time having bird to hit to occur, described outer panels 12, described wainscot 11 can absorb the energy that bird is hit, and simultaneously aluminum honeycomb panel 13 buffering that also can deform, further absorbs energy, and the common impact that bird is caused aircraft plays buffer action; Thereby the FR frame of protection aircraft is not breakdown, prevent from that bird meat from injecting in cabin, injure chaufeur or destroy aircraft system, to ensure that aircaft configuration meets CCAR-25.571 (e) clause.In addition, can also reduce and suffer that bird hits maintenance cost and the maintenance time of rear Aircraft Main structure.
Described outer panels 12, described wainscot 11 are all selected from polythene material, hit the weight of baffle plate to alleviate anti-bird.According to the flying speed of aircraft and birdstrike space, consider that birdstrike position is outer panels 12, described outer panels 12 is formed by 2 ~ 15 floor height molecular polyethylene material compactings, has the ability of enough resistance birdstrikes; And the thickness of described the first aluminum honeycomb panel 13 is between 15mm ~ 40mm; Described wainscot 11 is formed by 1 ~ 8 floor height molecular polyethylene material compacting.So design, rational in infrastructure, cost is low, and the impact resistant capability that can improve better anti-bird and hit baffle plate, has alleviated again weight simultaneously.In the present embodiment, 5056 aluminum honeycomb panels 13 of 5052 aluminum honeycomb panel 13 or 20 ~ 30mm that described aluminum honeycomb panel 13 is 30mm, and be embedded with swivel nut on aluminum honeycomb panel 13, mounting screw when being connected with FR frame; Described outer panels 12 and wainscot 11 are formed by 5 layers, 2 floor height molecular polyethylene materials compactings respectively.
Be different from the present embodiment, the agent structure 1 that described anti-bird is hit baffle plate also can be made up of two or more aluminum honeycomb panels, to strengthen protective capacities or to adapt to different fail-safe structures, between described adjacent two aluminum honeycomb panels, connects by high-molecular polythene material.In addition, described agent structure 1 also can be done corresponding change to material, thickness etc. according to actual needs.
As shown in Figure 3, described supporting construction 2 is made up of some fritters 21, in the middle of some fritters 21, is formed with space 22, hits baffle plate pass through with reinforcement and support etc. that FR frame is connected for the described anti-bird of connection.Described supporting construction 2 is consistent with the material of wainscot 11.Described reinforcement and FR frame joint place adopt the silaatic of one deck 2 ~ 3mm as isolated material.
For realizing above-mentioned utility model object, the utility model also provides a kind of anti-bird to hit the preparation technology of baffle plate, comprises the steps:
S1: hit the preparation requirement of the size and shape of baffle plate according to anti-bird, first aluminum honeycomb panel 13 and organic board are carried out respectively to machinework.Particularly, first by cutting machine, aluminum honeycomb panel 13 being cut, then by stretcher, the aluminum honeycomb panel 13 after cutting is stretched, is finally needed aluminum honeycomb panel 13 by the machine-shaping of three-dimensional milling machine.Meanwhile, by cutting machine and edge polisher, organic board is cut and edging successively.
S2: adopt PU film that organic board good machinework and aluminum honeycomb panel 13 are bonded together;
S3: adopt resin material to carry out edge sealing, in described resin material, the content of resin is between 50% ~ 60%.
Further, the preparation technology that described anti-bird is hit baffle plate also comprises the non-destructive test step being positioned at after described S3, and described non-destructive test step adopts X ray tester to hit baffle plate to described anti-bird and detects.If it is qualified to detect, can carry out follow-up spraying paint, mark, packaging.If detection nonconformity, processing again.
In sum, anti-bird of the present utility model is hit baffle plate by being provided with supporting construction 2, is convenient to be fixed on aircraft, and can destroy agent structure 1; Also be convenient to maintenance.Meanwhile, described outer panels 12, described wainscot 11 are high-molecular polythene material, the quality that has greatly alleviated anti-bird and hit baffle plate.Described in the time having bird to hit to occur, outer panels 12, described wainscot 11 can absorb the energy that bird is hit, and aluminum honeycomb panel 13 buffering that also can deform, further absorbs energy simultaneously, and the common impact that bird is caused aircraft plays buffer action; Thereby protection aircraft is not breakdown, prevent from that bird meat from injecting in cabin, injure chaufeur or destroy aircraft system, to ensure that aircaft configuration meets CCAR-25.571 (e) clause.In addition, can also reduce and suffer that bird hits maintenance cost and the maintenance time of rear Aircraft Main structure.In addition, the preparation technology of this utility model is simple, is easy to realize suitability for industrialized production.
Above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not depart from the spirit and scope of technical solutions of the utility model.
