1 and 2, the wind tunnel test system 100 according to an embodiment of the present invention includes a wind tunnel test model 110, a wind tunnel scale 120, a fixed support 130, a controller 140, and a wind tunnel. A scale mounting mechanism 150. Wind tunnel test system 100 is a facility disposed inside the wind tunnel for the wind tunnel test to examine the effect of the wind on the structure and the like. Hereinafter, the present embodiment is limited to the wind tunnel test of the aircraft for convenience of description, but the present invention is not limited thereto, and the same can be applied to the wind tunnel test of various machines or objects.

The wind tunnel test model 110 is a model that is reduced to the same shape as that of an aircraft requiring a wind tunnel test. The wind tunnel test model 110 may perform a wind tunnel test on behalf of an actual aircraft, and may design an actual aircraft using data obtained during the wind tunnel test. One side of the wind tunnel test model 110 as described above may be formed with a work hole 112 to operate the wind tunnel scale detachment mechanism 150.

Wind tunnel scale 120 is a test equipment for measuring the three-axis torque and moment of the wind tunnel test model 110 during the wind tunnel test. The wind tunnel scale 120 may be integrally provided inside the wind tunnel test model 110.

The fixed support 130 is a member for supporting the wind tunnel scale 120 and the wind tunnel test model 110 in the wind tunnel. The fixed support 130 is firmly connected to the wind tunnel scale 120 so that the wind tunnel scale is not shaken or vibrated during the test. The fixed support 130 may be formed to have a predetermined height so that the wind tunnel test model 110 is positioned at the central portion of the wind tunnel.

The controller 140 is a device for storing and analyzing the wind tunnel test data of the wind tunnel test model 110 by receiving a detection value detected by the wind tunnel scale 120 during the wind tunnel test. Therefore, the controller 140 may be connected to the wind tunnel scale 120 by a connection line 142 such as an electric wire.

The wind tunnel scale detachment mechanism 150 as described above may be operated through the work hole 112. In addition, the wind tunnel scale detachment mechanism 150 may be formed in a structure that can be firmly coupled to the wind tunnel scale 120 to the fixed support 130, as well as to easily disassemble the wind tunnel scale 120 from the fixed support. Can be.

3 is an exploded perspective view showing the wind tunnel scale detachment mechanism 150 shown in FIG. 2, FIG. 4 is a perspective view showing a combined state of the wind tunnel scale detachment mechanism 150 shown in FIG. 6 is a cross-sectional view showing the main part of the wind tunnel scale mounting and detachment mechanism 150 shown in FIG. 4.

3 to 6, the wind tunnel scale mounting mechanism 150 according to an embodiment of the present invention includes a wind tunnel scale coupling member 160 and wind tunnel scale disassembly member 170.

Wind tunnel scale coupling member 160 may be provided on the top of the fixed support (130). Wind tunnel scale coupling member 160 may be integrally formed on the top of the fixed support 130, or may be mounted in a very solid structure on the top of the fixed support (130).

On the other hand, at one end of the wind tunnel scale 120 may be formed in the tapered portion 122 in a shape that decreases in diameter toward the end. In addition, the wind tunnel scale coupling member 160 may be provided with a coupling hole 162 into which the taper portion 122 of the wind tunnel scale 120 is fitted and coupled in a press-fit manner.

Coupling hole 162 may be formed in the wind tunnel scale coupling member 160 to penetrate the inside of the wind tunnel scale coupling member 160 in a straight line shape. The coupling hole part 162 may include a first coupling part 164 and a second coupling part 166. The first coupling portion 164 may be formed at one end of the coupling hole 162 to be coupled to the tapered portion 122. The second coupling part 166 may be formed at the other end of the coupling hole part 162 such that the wind tunnel scale disassembling member 170 is movably inserted along the coupling hole part 162 in a straight line.

Here, the first coupling portion 164 may be formed in a tapered shape corresponding to the tapered portion 122. That is, since the taper portion 122 of the wind tunnel scale 120 is coupled to the first coupling portion 164 of the coupling hole portion 162 by a press-fit method, the tapered portion 122 and the first coupling portion 164 have a large load. It can be combined in a surface contact manner that can withstand.

In addition, the protrusion 164a may protrude from the contact surface of any one of the first coupling portion 164 and the tapered portion 122, and the contact surface of the other of the first coupling portion 164 and the tapered portion 122. An insertion groove 122a into which a protrusion is inserted may be formed when the first coupling portion 164 and the tapered portion 122 are coupled to each other. Therefore, the coupling structure of the first coupling portion 164 and the tapered portion 122 may be more robust, and the coupling position of the first coupling portion 164 and the tapered portion 122 may be accurately set. Hereinafter, in the present embodiment, as shown in FIGS. 5 and 6, the protrusion 164a protrudes from the first coupling part 164 and the insertion groove 122a is formed in the tapered part 122. However, the position, shape and number of formation of the protrusions and the insertion grooves are not particularly limited, and various modifications may be possible depending on the design conditions and circumstances of the wind tunnel scale coupling member 160.

However, when the tapered portion 122 and the first coupling portion 164 are coupled in a surface contact manner as described above, the wind tunnel scale 120 and the wind tunnel scale coupling member 160 are coupled to the wind tunnel scale 120 for disassembly. A strong force must be added in the axial direction A of the hole portion 162. By the way, the connection line 142 connecting the wind tunnel scale 120 and the control unit 140 is bound through the other end of the coupling hole 162 is not coupled to the wind tunnel scale 120.

Therefore, conventionally, the wind tunnel scale disassembling screw is inserted into the axial direction (A) and the inclined direction of the coupling hole 162 in the fixing support 130 to use the method of pushing the end of the tapered portion 122 at an oblique angle. Doing. That is, conventionally, the wind tunnel scale disassembly screw is disposed at a position not blocking the other end of the coupling hole 162, and the action force of the wind tunnel scale disassembly screw is inclined to the tapered portion 122 of the wind tunnel scale 120. have. Since the conventional method has a limitation in expanding the size of the wind tunnel scale disassembly screw, a small size wind tunnel disassembly screw is used, and thus, the thread is worn frequently when a large force is applied. In addition, since the action force of the screw for disassembling the wind tunnel scale acts in an oblique direction other than the disassembly direction A of the wind tunnel scale 120, that is, in the axial direction A of the coupling hole 162, the wind tunnel scale 120 is actually used. The force used for disassembly of the wind tunnel scale disassembly may be smaller than the force of the screw, thereby providing a greater force than the force for disassembling the wind tunnel scale 120 to the wind tunnel scale disassembly screw.

In order to solve the above problems, in the present embodiment, the wind tunnel scale disassembling member 170 is disposed at the other end of the coupling hole 162, that is, in the second coupling part 166, in the axial direction A of the coupling hole 162. It can be inserted movably, and the screw for disassembling the wind tunnel scale can be omitted.

3 to 6, the wind tunnel scale disassembling member 170 may disassemble the wind tunnel scale 120 at one end of the coupling hole 162, that is, at the first coupling unit 164 when the wind tunnel scale 120 is disassembled. It is a member to push outward (A). The wind tunnel scale disassembling member 170 moves in the direction A of disassembling the wind tunnel scale 120 in the second coupling portion 166 of the coupling hole 162, that is, in the axial direction A of the coupling hole 162. Possibly inserted.

The through-hole portion 172 may be formed in the wind tunnel scale disassembling member 170 so that the connection line 142 connecting the wind tunnel scale 120 and the controller 140 may be disposed therethrough. The through hole part 172 may be formed in the wind tunnel scale disassembling member 170 to penetrate the inside of the wind tunnel scale disassembling member 170. The through-hole part 172 may be disposed in communication with the hole 124 formed in the coupling hole 162 or the wind tunnel scale 120 when the wind tunnel scale coupling member 160 and the wind tunnel scale disassembling member 170 are connected to each other. Hereinafter, in the present exemplary embodiment, the through hole part 172 is elongated in the same direction as the coupling hole part 162. However, the through hole 172 may be modified in various shapes such as a curved line or a broken line in the wind tunnel scale disassembling member 170 according to the design conditions and circumstances of the wind tunnel scale detachable mechanism 150.

For example, the wind tunnel scale disassembling member 170 according to the present embodiment includes a main body portion 174 and a main body portion 174 movably inserted into the second coupling portion 166 of the coupling hole portion 162. An operation unit 176 formed at another portion of the main body unit 174 that is not inserted into the coupling hole unit 162 may be provided to manipulate the operation.

An end portion of the main body portion 174 may be in contact with the tapered portion 122 inside the coupling hole 162. The main body 174 may be formed in a cylindrical shape having a through hole 172 formed therein. A male screw S1 may be formed on an outer circumferential surface of the main body 174, and a female screw S2 to which the male screw of the main body 174 is movably fastened to the second coupling part 166 of the coupling hole 162. Can be formed. Therefore, when the main body portion 174 is rotated by the operation portion 176, the main body portion 174 is moved in the direction away from the second coupling portion 166, or the main body portion 174 is the second coupling portion ( 166 may be moved in the direction of insertion.

As shown in FIG. 5, if the end portion of the tapered portion 122 is positioned inside the first coupling portion 164, the outer diameter of the main body portion 174 may be the same as the outer diameter of the end portion of the tapered portion 122, or It can be formed small. That is, when disassembling the wind tunnel scale 120, the main body 174 may be inserted into the first coupling part 164 of the coupling hole 162 while pushing the taper part 122. If the outer diameter of the body portion 174 is larger than the outer diameter of the end portion of the tapered portion 122, the body portion 174 may be caught by the first coupling portion 164 when the wind tunnel scale 120 is disassembled.

On the other hand, as shown in FIG. 6, if the end portion of the tapered portion 122 is disposed to protrude inside the second coupling portion 166 through the first coupling portion 164, the main body portion 174 is provided. The outer diameter of may be the same as or larger than the outer diameter of the end of the tapered portion (122). That is, when disassembling the wind tunnel scale 120, the main body 174 does not need to be inserted into the first coupling portion 164 of the coupling hole 162 in the process of pushing the tapered portion 122. Therefore, the outer diameter of the body portion 174 may be larger than the outer diameter of the end portion of the tapered portion 122 in order to ensure the maximum contact area between the tapered portion 122 and the body portion 174. Therefore, the action force of the wind tunnel scale disassembling member 170 can be transmitted to the wind tunnel scale 120 more effectively.

The operation unit 176 is a member that rotates the main body 174 to insert the main body 174 into the coupling hole 162 when the wind tunnel scale 120 is disassembled. The operation unit 176 may be formed at a portion of the main body 174 that is not inserted into the coupling hole 162 when the wind tunnel scale 120 is disassembled.

For example, the operation unit 176 may be formed to protrude in a hexagonal cross-sectional shape along a circumference of the outer circumference of a portion of the main body 174. That is, since the operation unit 176 is formed in the same shape as the hexagonal head of the bolt, it is possible to easily rotate the main body unit 174 together with the operation unit 176 using a tool such as a hexagon wrench. However, the operation unit 176 is not limited to the hexagonal head shape of the bolt, the structure and shape of the operation unit 176 may be variously modified according to the design conditions and circumstances of the wind tunnel scale detachment mechanism 150.

Looking at the assembly process and disassembly process of the wind tunnel scale mounting and detachment mechanism 150 according to an embodiment of the present invention configured as described above are as follows.

First, the assembly process of the wind tunnel scale detachment mechanism 150 will be described in detail.

The wind tunnel scale coupling member 160 is firmly mounted on the upper portion of the fixed support 130, and the wind tunnel scale 120 is firmly mounted inside the wind tunnel test model 110.

Then, the tapered portion 122 of the wind tunnel scale 120 is inserted into and coupled to the first coupling portion 164 of the coupling hole 162 of the wind tunnel scale coupling member 160.

As such, when the taper 122 and the first coupling part 164 are coupled in a surface contact manner, the wind tunnel scale 120 may be supported very firmly by the wind tunnel scale coupling member 160. Therefore, the wind tunnel scale 120 may be prevented from shaking or vibrating about the connection portion with the wind tunnel scale coupling member 160 during the wind tunnel test, and thus various data obtained during the wind tunnel test of the wind tunnel test model 110. There is no error in the wind tunnel test reliability can be secured.

Next, the connection line 142 connected to the wind tunnel scale 120 is disposed to pass through the coupling hole 162 of the wind tunnel scale coupling member 160 and the through hole 172 of the wind tunnel scale disassembling member 170, and the state thereof. In the wind tunnel scale disassembling member 170 is fastened to the second coupling portion 166 of the coupling hole 162 of the wind tunnel scale coupling member 160. Therefore, the fastening operation of the wind tunnel scale disassembling member 170 and the wind tunnel scale engaging member 160 is not hindered by the connecting line 142, and the connecting line 142 is also the wind tunnel scale disassembling member 170 and the wind tunnel scale engaging member 160. Is not adversely affected by the

As described above, the connecting line 142 passing through the coupling hole 162 and the through hole 172 is connected to the controller 140.

In the fastening operation of the wind tunnel scale disassembling member 170, the operation unit 176 is rotated in a direction in which the main body 174 of the wind tunnel scale disassembling member 170 is fastened to the second coupling unit 166 by using a hexagon wrench. You can.

At this time, the body portion 174 of the wind tunnel scale disassembling member 170 is fastened to a position which does not come into contact with the taper portion 122 of the wind tunnel scale 120, or the pressure is applied to the taper portion 122 of the wind tunnel scale 120. It is fastened only to the position where only contact is made without adding.

The coupling operation of the wind tunnel scale coupling member 160 and the wind tunnel scale 120 and the fastening operation of the wind tunnel scale coupling member 160 and the wind tunnel scale disassembly member 170 are all work holes 112 formed in the wind tunnel test model 110. This can be done through.

On the other hand, in the wind tunnel scale mounting mechanism 150, the wind tunnel scale 120 will be described in detail.

First, using the hexagon wrench, the operation unit 176 of the wind tunnel disassembly member 170 is rotated in the fastening direction. Therefore, as the operation unit 176 is rotated, the main body unit 174 is inserted into the second coupling unit 166 while being inserted.

As described above, when the operation unit 176 is continuously rotated to insert the main body 174 into the second coupling part 166, the wind tunnel scale disassembling member is in contact with the main body 174 and the tapered part 122. The action force of 170 is transmitted to the wind tunnel scale 120.

Therefore, since the force of the wind tunnel scale disassembling member 170 acts in the direction in which the wind tunnel scale 120 is separated from the wind tunnel scale coupling member 160, the tapered portion 122 of the wind tunnel scale 120 is coupled to the coupling hole 162. It may be separated from the first coupling portion 164 of the.

At this time, since the connection line 142 is disposed inside the through hole 172 when the wind tunnel scale 120 and the wind tunnel scale coupling member 160 are disassembled, the connection line 142 is not affected by the rotation of the wind tunnel scale disassembly member 170. Do not.

Further, since the action force of the wind tunnel scale disassembling member 170 acts on the taper portion 122 in the same direction as the disassembly direction of the wind tunnel scale 120, the action force of the wind tunnel scale disassembling member 170 disassembles the wind tunnel scale 120. Can be used for both.

When the press-fit engagement state of the taper portion 122 and the first coupling portion 164 is released by the action force of the wind tunnel scale disassembling member 170, the wind tunnel scale 120 is released from the coupling hole 162 of the wind tunnel scale coupling member 160. ) Can be easily removed.

Disassembly of the wind tunnel scale coupling member 160 and the wind tunnel scale 120 may also be performed through the work hole 112 formed in the wind tunnel test model 110.
