In existing complicated landform during comb test wind speed, probe often inconvenience arrives the position required for testing crew, or by changing model, must cause certain redundant work amount to reach this object; Not enough for this, the utility model provides a kind of shaped end comb being applicable to complicated landform wind tunnel test, this shaped end comb can reach flexible, easy and the object of complicated relief block each position fluctuating wind speed in wind tunnel test efficiently, obtains the fluctuating wind speed near landform model surface position under the prerequisite of particularly not damage model.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of shaped end comb being applicable to complicated landform wind tunnel test, comprise housing, housing is vertically arranged with many edges and protrudes from the air intake probe of housing in direction windward, be provided with the flexible hose be connected one by one with air intake probe in housing, described flexible hose stretches out housing away from one end of air intake probe and is connected with the electric pressure scaner for testing wind speed; Described housing is arranged to point of a knife shape near the bottom of air intake probe, and 3 ~ 5 air intake probe manufacturing cambers of housing bottom, the termination, outside of the air intake probe of arcuate structure is parallel to wind speed direction.
As a kind of preferred version of the present utility model, described housing is arranged to the point of a knife shape of arcuate structure near the bottom of air intake probe, and the radian of the air intake probe of arcuate structure and the point of a knife radian of housing bottom adapt.
As another kind of preferred version of the present utility model, the center line of the termination, inner side of the air intake probe of arcuate structure and the center line of flexible hose tangent.
As another preferred version of the present utility model, the inside of described housing is arranged and flexible hose undercut one to one, and described flexible hose is fixed in corresponding undercut.
As a kind of improvement project of the present utility model, the xsect streamlining shape of described housing.
Compared with prior art, the utility model tool has the following advantages:
1, the utility model is implemented mainly through the improved shape of part air intake probe and housing, ensure that under the precondition of test accuracy, solve the inconvenient problem of complicated landform surface wind speed, can accurately, easily testing complex relief block close to the wind speed of surface location, the efficiency of similar wind tunnel test can be improved significantly.
2, not damage model, simply, directly by this shaped end comb can be arranged in the position of complicated relief block close to surface, improve the efficiency of wind tunnel test comparatively significantly.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, be applicable to a shaped end comb for complicated landform wind tunnel test, comprise housing 1, housing 1 is vertically arranged with many (being at least greater than 5 in prior art) edge and protrudes from the air intake probe 2 of housing 1 in direction windward, in the present embodiment, air intake probe 2 adopts metal probe.Be provided with the flexible hose 3 be connected one by one with air intake probe 2 in housing 1, flexible hose 3 stretches out housing 1 away from one end of air intake probe 2 and is connected with the electric pressure scaner for testing wind speed, and electric pressure scaner does not draw in the drawings.Housing 1 is arranged to point of a knife shape near the bottom of air intake probe 2, in the present embodiment, housing 1 is arranged to the point of a knife shape of arcuate structure near the bottom of air intake probe 2, different according to applicable landform fluctuating quantity, 3 ~ 5 air intake probes 2 bottom housing 1 can be made into arc, and the radian of the air intake probe 2 of arcuate structure and the point of a knife radian of housing 1 bottom adapt.Need to ensure the tangential angle at air intake probe 2 two ends, the termination, outside of the air intake probe 2 of arcuate structure is parallel to wind speed direction, the center line of the termination, inner side of the air intake probe 2 of arcuate structure and the center line of flexible hose 3 tangent.
In order to enable comb termination as far as possible close to model surface, the longitudinal size of termination must be reduced as much as possible; On the other hand, ensure that significant transmission error can not occur the air pressure transmission in the finite space again, therefore, the xsect of housing 1 is kept streamline shape, as shown in Figure 3,4, but overall side forms point of a knife shape, and namely sectional dimension progressively reduces toward position, termination.The inside of housing 1 is arranged and flexible hose 3 undercut one to one, and flexible hose 3 is fixed in corresponding undercut, ensures can not to overlap and extrude between different flexible hoses 3.
When using this shaped end comb, being arranged on by this shaped end comb is applicable on complicated landform flow tunnel testing device, as shown in Figure 5, horizontal slide rail 4 is arranged on the top of wind-tunnel inwall, shaped end comb is arranged on vertical slide rail 5 and also can vertically slides up and down by slide rail 5, vertical slide rail 5 can be gone forward laggard line slip at horizontal slide rail 4, and the air intake probe 2 bottom housing 1 is near complicated relief block 6, and air intake probe 2 is with direction is corresponding windward.The utility model adopts the housing of point of a knife shape and the air intake probe 2 of circular arc to combine, ensure that air intake probe 2 termination is parallel to wind speed direction completely on the one hand, ensure that the rubber tube system of air intake probe 2 and housing 1 inside is at pressure bang path mean curvature consecutive variations on the other hand, the pressure delivery system of metal probe and inner flexible hose is accomplished " only curved do not roll over ", to ensure that blast transmission error does not occur in small space; Can form the comb termination of point of a knife shape under above 2 prerequisites, just can ensure enough test accuracy while the physical dimension of reduction comb termination, directly the wind speed realized near landform model surface position is tested.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
