Abstract
The utility model relates to an air axle which can resolve the influence on the balance testing from the air supplying pipeline in a wind tunnel test. The utility model is characterized in that a section of pipeline between the a conduit (2) behind the last fixing supporting point (1) and the floating interface (3) of the conduit (2) is bent to an U-shaped section which is perpendicular to the conduit (2), at least one flexible section (4) is arranged on the conduit (2), and at least one flexible section (4) is arranged on the perpendicular section pipeline of the U-shaped section. The perpendicularly arranged flexible section can absorb the expanding of the flexible section transversely arranged, and the expanding of the flexible section vertically arranged can be absorbed by the flexible section transversely arranged. The utility model has the advantages that the utility model has six freedom degrees, has a small influence on the balance, and has a strong capability to overcome the pressure influence and the temperature influence.
Description
One, technical field
The utility model relates to a kind of supply air line that can solve in the wind tunnel test to the equipment of the problem that influences of aerodynamic balance measuring.
Two, background technology
For example turbine engine simulation test, thrust vectoring test, jet test, the test of air blowing FLOW CONTROL all needs pressure-air is incorporated into test model inside from high-pressure air source in a lot of wind tunnel tests.Therefore need to arrange the pipeline from the high-pressure air source to the test model, but this pipeline that is connected with test model can influence aerodynamic balance measuring.Therefore, need to solve the influence problem of supply air line in the test to aerodynamic balance measuring.Past is used the way that equipment such as air-bearing, metallic bellows connect supply air line and test model always and solves this problem.Exigent test can not meet the demands these solutions to dynamometry for some.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of supply air line that can solve in the wind tunnel test to the facilities air bridge of the problem that influences of aerodynamic balance measuring.
Air bridges is to solve most advanced the best way that supply air line influences this class problem of aerodynamic balance measuring at present.Air bridges is by making up some flexible unit (claiming expansion joint again), make that the supply air line integral rigidity is very little, reaching little of negligible purpose to the aerodynamic balance measuring influence.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of air bridges, it is characterized in that: pipeline to one section pipeline between the floater port of this pipeline of last the fixed pivot back in the supply air line is bent into " U " shape shape section vertical with this pipeline, and on pipeline, be provided with a flexible joint (being horizontal flexibility joint) at least, on the vertical section pipeline of " U " shape shape section, be provided with a flexible joint (the promptly perpendicular flexibility joint of putting) at least.
Further scheme is: respectively be provided with a flexible joint on the pipeline at the two ends of " U " shape shape section, the vertical section pipeline is provided with a flexible joint.
In the utility model, described " U " shape also comprises down " U " shape.
In the utility model, described flexible joint can be a various flexible joint of the prior art, as the flexibility joint of mainly being made up of corrugated tube and floating ring.It is the expansion of constraint corrugated tube that floating ring mainly acts on.
The utility model compared with prior art, the beneficial effects of the utility model are, the perpendicular flexibility joint of putting can absorb the expansions of two horizontal flexible joints, perpendicular expansion of putting flexible joint can be absorbed by two horizontal flexibilities joints.Its advantage is to have six-freedom degree, and is little to the influence of balance, and self has the stronger ability that overcomes pressure influence, temperature effect.Thus, by in supply air line, adding air bridges, can the transferring high voltage air, make whole supply air line very little simultaneously to the aerodynamic balance measuring influence.
Four, description of drawings
The layout of Fig. 1 air bridges.
Among the figure: 1-fixed pivot, 2-pipeline, 3-floater port, 4-flexible joint.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
As Fig. 1, a kind of air bridges, it is characterized in that: pipeline 2 to one section pipeline between the floater port 3 of this pipeline 2 of last fixed pivot 1 back in the supply air line is bent into " U " shape shape section vertical with this pipeline 2, and respectively be provided with a flexible joint 4 on the pipeline 2 at the two ends of " U " shape shape section, the vertical section pipeline is provided with a flexible joint 4.
Claims (2)
1, a kind of air bridges, it is characterized in that: pipeline (2) to one section pipeline between the floater port (3) of this pipeline (2) of last fixed pivot (1) back in the supply air line is bent into " U " shape shape section vertical with this pipeline (2), and on pipeline (2), be provided with a flexible joint (4) at least, on the vertical section pipeline of " U " shape shape section, be provided with a flexible joint (4) at least.
2, air bridges according to claim 1 is characterized in that: respectively be provided with a flexible joint (4) on the pipeline (2) at the two ends of " U " shape shape section, the vertical section pipeline is provided with a flexible joint (4).
