Abstract
The utility model discloses a large airplane water tank made of a filament wound composite material. The large airplane water tank comprises a metal lining, a reinforcing layer and a protection layer, and the reinforcing layer is arranged between the metal lining and the protection layer. Compared with large airplane water tanks in prior art, the large airplane water tank has the advantages of being light, high in bearing capacity, low in cost and good in reliability.
Description
Technical field
The utility model relates to a kind of water tank, especially relates to the large water tank of airplane of a kind of filament wound composite.
Background technology
Along with the establishment of China Shang Fei company, domestic large aircraft has formally pulled open prelude; And being about to emerge and indicating that especially China has possessed the technical merit of independent development airliner of home-built aircraft C919.Large aircraft highlights safety, economy, traveling comfort and the feature of environmental protection.High request on these performances has determined the urgency of composite material demand and certainty.Composite material is a kind of new material that is made of high strength, high rigidity reinforcing material, has the series of advantages such as high strength, high rigidity, good fatigue resistance, resistance to corrosion.Adopt aboard composite material to mean the structural weight that can obviously alleviate aircraft, improve the performance of aircraft.The present delivered of super Jumbo A380 as one of two large manufacturers' of large aircraft European space truck group development is used, this technique for aircraft composite accounts for 25%, the B787 aircraft of U.S.'s Boeing development successfully rolls off the production line, be about to begin first-fly and pay the course line use, it is used composite material and accounts for about 50%, significantly alleviated aircraft weight owing to the application of composite material, made B787 improve fuel efficiency and reach 20%.
In various airplane components, large water tank of airplane (comprising potable water and sewage water tank) is requisite integrated system in the airliner.At present, domestic can be for domestic airliner provides the company of cistern system less, and gordian technique is not advanced, manufacturing technology is by offshore company's long-term control, the import of parts not only will be spent more foreign exchanges, the what is more important delivery cycle is long, speed of response is slow.Therefore, the research of the tank shell that uses on the airliner is started with, prepare and satisfy the autonomous property right cistern system of having of large aircraft airworthiness requirement and become extremely urgent problem.Up to now, the water tank of airplane technology mainly has following shortcoming:
1, the water tank of existing plastic inner container is apparent in view to large overall aircraft weight loss effect, but expensive plastic inner container die sinking expense has improved the manufacturing cost of such water tank in manufacturing process; Simultaneously, at high temperature in the plastic inner container difficult quality of potable water up to standard.
2, because existing simple metal material water tank intensity is limited, for the performance that improves water tank can only increase container thickness, can increase the manufacture difficulty of container on the one hand, thereby cause manufacturing deficiency, on the other hand, cause overall aircraft weight to increase.
The utility model content
The utility model provides a kind of filament wound composite large water tank of airplane for the technical matters that exists in the above-mentioned prior art, and this water tank is lightweight, load-carrying capacity is high, cost is low and good reliability.
The purpose of this utility model is to be achieved through the following technical solutions:
The large water tank of airplane of a kind of filament wound composite comprises metal inner lining, enhancement Layer and protective cover, and described enhancement Layer is arranged between metal inner lining and the protective cover.
Described metal inner lining is corrosion-resistant steel or aluminium alloy lining.
Described enhancement Layer is the carbon fiber composite material layer, and this carbon fiber composite material is vertical winding fibrage that the cylindrical shell at metal inner lining twines.
Described protective cover is the glass fiber compound material layer, and this glass fibre composite bed adopts glass fibre entirely to twine formation outside enhancement Layer.
The utlity model has following advantage:
1, the performance of water tank matches same kind of products at abroad, but cost about 50%;
2, because fibre strength is much higher than plain metal, and proportion is little, can alleviate the quality of container, improves the container load-carrying capacity, thereby reaches the purpose that significantly alleviates aircraft weight;
3, the wall of container internal stress is inhomogeneous, and isotropic metallic material is made pressure container and do not brought into play all potential of metallic material.The anisotropy of composite material just in time can remedy this deficiency, and machine direction intensity is the highest, in order to bear hoop-stress, other direction intensity is lower, then just in time bears other low stress, can give full play to the potential of material, and stable manufacturing process is difficult for producing defective.
Description of drawings
Fig. 1 be large water tank of airplane disclosed in the utility model partly cut open figure.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in Figure 1, the large water tank of airplane of filament wound composite disclosed in the utility model mainly is comprised of metal inner lining 1, enhancement Layer 2 and protective cover 3.Described enhancement Layer 2 is arranged between metal inner lining 1 and the protective cover 3.Metal inner lining 1 is corrosion-resistant steel or aluminium alloy lining.Described enhancement Layer 2 is the carbon fiber composite material layer, and this composite layer is vertical winding layer that the cylindrical shell at metal inner lining 1 twines.Described protective cover 3 is the glass fiber compound material layer, and this glass fiber compound material layer twines formation entirely at enhancement Layer 2 outer employing glass fibres.
These embodiment are interpreted as only being used for explanation the utility model and are not used in restriction protection domain of the present utility model.After the content of having read the utility model record, those skilled in the art can make various changes or modifications the utility model, and these equivalences change and modification falls into the utility model claim limited range equally.
