Description
Technical field
The present invention relates to a kind of rectification part of wind tunnel test, a kind of forming method of rectification part, one kind to include this
The pant device of the wind tunnel test of kind rectification part and a kind of assembly method of pant device.
Background technology
So far, wind-tunnel technique personnel mainly use the metal/non-metal radome fairing of frame segmentation, follow-up gold
Belong to covering or felt-cloth etc. and tighten covering, so as to form the appearance profile of radome fairing.The metal/non-metal radome fairing of frame segmentation it is whole
It is difficult to accomplish fairing to flow shape, and rectification effect is only capable of substantially meeting low speed (subsonic speed) wind-tunnel of less demanding to rectification effect
The requirement of experiment seldom uses this design in (across/supersonic speed) experiment at a high speed.
The content of the invention
It is an object of the present invention to provide a kind of new wind tunnel test pant devices, can overcome existing skill
The defects of art is current.
A kind of pant device of the purpose by rectification part according to the present invention and including this rectification part is real
It is existing.According to the present invention, the rectification part is composite material component, after being preset in the composite material component for accommodating
The nesting of phase fastener, it is described nested for countersunk head nesting.
Be typically due to the anisotropic of composite material, thus composite technology in the design of wind tunnel model radome fairing,
Especially fail to be used always in the design of high-speed wind tunnel model radome fairing.The present invention breaches the bottleneck of the prior art,
And demonstrate its reliability, security by multiple high wind tunnel testings.The New Wind Tunnel experiment rectification part and radome fairing
Device is suitable for almost the rectification purposes of all half module model in wind tunnel.
In addition, the present invention solves the connectivity problem of composite material component and metalwork.By being reserved on rectification part
The assembling that hole position docks d type frame for rectification part with other component, such as steel support plate or steel uses, on rectification part
No longer need tapping.
Composite material generally using paving be molded, it is contemplated that if composite material shaping after again drilling easily cause it is compound
Material product layering reduces bonding strength, and a preferred embodiment of the invention, the nesting can be in the rectification part
The composite plys of part are preset at before curing in the composite plys.The present invention is using the method for prefabricated nesting, solution
It has determined the high intensity connectivity problem of composite products and metal.In addition, the rectification part so after curing molding has carried hole
Position without drilling again, avoids the problem of composite material is not suitable for drilling assembling due to anisotropic.

Often it is metal parts, is, for example, steel.
A part for back segment rectification part 2 is also shown in Fig. 2 with partial enlargement, its composite material paving is shown
Layer 12, presets the countersunk head nesting 13 of aluminum in composite plys, and countersunk head nesting 13 is spread by glued membrane 14 and composite material
Layer 12 connects.
Fig. 3 shows the schematic diagram of composite plys used by rectification part in Fig. 2.Fig. 4 shows rectification part
The schematic diagram of sandwich of layers in used composite plys.With reference to Fig. 3 and Fig. 4 illustrate rectification part structure and into
Type method.
First, during fabrication, coordinate former or male mold, be laid with the first outer laying 121, the first glue successively in a mold
Film layer 122, sandwich of layers 123, the second adhesive film 124 and the second outer laying 125, the first outer laying 121 and second are spread outside
Layer 125 can select glass fibre.
When being laid with sandwich of layers 123, as shown in FIG. 4, honeycomb is laid on the most areas of sandwich of layers 123
128, the specification of honeycomb is depending on carrying demand；Edge sealing 126, such as glass fibers are laid with along the edge of honeycomb 128
Dimension or carbon fiber, edge sealing 126 carry out cementation solidifying with honeycomb 128 by glue or glued membrane.It is embedding that countersunk head is reserved in edge sealing 126
Set 13 is threadedly coupled for the later stage with support plate, and the surface mount that countersunk head nesting 13 is contacted with composite plys has 1 to 2
Layer glued membrane, later stage can be with composite plys one curing moldings, and the rectification part after such curing molding has carried counter sink
Position without drilling again, avoids the problem of composite material is not suitable for drilling assembling due to anisotropic.
The endoporus of countersunk head nesting is blocked by composite plys in order to prevent, can block countersunk head nesting with closeouts in advance
Endoporus, rectification part shaping after closeouts are taken out again.
After the material of honeycomb 128 and edge sealing 126 is laid, to prevent honeycomb 128 from being carried with edge sealing 126
Ability mutation is excessive, to around edge sealing honeycomb, the honeycomb of 2cm is carried out using casting glue 127 around such as edge sealing
Embedding.
Finally, make the first outer laying 121, the first adhesive film 122, sandwich of layers 123, outside the second adhesive film 124 and second
