The rudder 3 is attached to the fins 4 by screws (not shown).
Is transmitted from the rudder 3 to the fin 4 through the joint between the fin 4 and the fin 4. Further, a strain gauge (measuring means) 2 for measuring the amount of strain is attached to this joint portion. At the time of the test, wind was applied to the fins 4 and the rudder 3 in the wind tunnel, and the strain was detected by the strain gauge 2. From the distortion, a load such as a load acting between the fin 4 and the rudder 3 is measured.

Incidentally, a coating agent (moisture-proofing agent) 5 is applied to the strain gauge 2 for the purpose of preventing moisture absorption (hatched portion in the figure). Further, since the strain gauge 2 is extremely sensitive to a temperature change, the strain gauge 2 is covered with a cover 6 so as not to be affected by wind or the like as much as possible. As described above, in the conventional apparatus, the coating agent 5 is applied to the strain gauge 2, and the strain gauge 2 is further covered with the cover 6.

However, in such a conventional technique, even when the strain gauge 2 is covered with the cover 6, the wind flows out of the gap between the fin 4 and the rudder 3 at the time of the test, which affects the aerodynamics. And there is a problem that accurate measurement data cannot be obtained. The present invention has been devised in view of such a problem, and provides a fluid test apparatus capable of eliminating such influence on aerodynamics (air turbulence) and improving the accuracy of measurement data.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a fluid test apparatus according to an embodiment of the present invention.
FIG. 1 is a schematic perspective view showing the entire configuration. The fluid test device of the present embodiment is configured as a wind tunnel test device for performing a wind pressure test in a wind tunnel. In addition, the same members as those in the related art are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 1, in the wind tunnel test apparatus of the present invention, an elastic protective material (here, silicone rubber) 1 is used in place of a conventional cover (see reference numeral 6 in FIG. 2). It is configured. This silicone rubber 1
Like the conventional cover, is provided to prevent the wind from directly hitting the strain gauge 2. The silicon rubber 1 protects the strain gauge 2.

More specifically, the silicone rubber 1 is poured into a space between a fin 4 as a structural member and the rudder 3, that is, an installation portion of a strain gauge (measuring means) 2, and the fin 4 and the rudder 3 are connected to each other. The silicone rubber 1 is molded so that there is no gap between them. In addition, as the material for protection 1, other than silicon rubber, any other material may be used as long as it is flexible and hardly affects the rigidity of the measuring element of the strain gauge 2. Or urethane rubber can be applied.

In the case where the silicone rubber 1 is used as the above-mentioned protective material, it is possible to save a coating agent which has been applied conventionally. This is because the silicone rubber itself can be expected to have a moisture-proof effect. Further, when a material other than silicon rubber, which can be expected to have a moisture-proof effect, is applied as the protective material, the application of the coating agent can be omitted as described above.

Since the wind tunnel test apparatus (fluid test apparatus) according to one embodiment of the present invention is configured as described above, the silicon rubber 1 is poured directly between the fins 4 and the rudder 3 and formed. Thereby, the gap between the rudder 3 and the fin 4 can be eliminated. Therefore, even when the test is performed in the wind tunnel, the wind does not flow out of the gap as in the conventional case, and there is an advantage that the measurement accuracy is greatly improved. In addition, the simple configuration as described above has an advantage that there is almost no increase in cost, and when silicon rubber is used, there is an advantage that application of a coating agent can be eliminated.

The embodiments of the present invention are not limited to those described above, and various modifications can be made without departing from the spirit of the present invention. For example, the structural members are not limited to the fins 4 and the rudder 3 described above, and can be applied to various members that receive fluid pressure (wind pressure, water pressure, etc.).
