タとなる。2. Description of the Related Art FIG. 6 is a view showing the outline of a wind tunnel test of a model using an interpolation balance. A wind tunnel test model 1 is arranged in a wind tunnel 10, an air flow 20 flows, and the model is inserted from the interpolation balance. The test is performed by taking data. An interpolation balance (generally a non-gauge 6-component force balance) is inserted and attached to the wind tunnel test model 1, and the interpolation balance is connected to a sting and supported by a support. 11
The support portion 11 is fixed to the strut 6 and supports the model 1. In such a wind tunnel test, the tip of the wind tunnel test model 1 is tilted from the mounting center line due to the air flow 30. If this tilt is large, the periphery of the end of the model 1 and the support portion 11 (the combination of the insertion balance and the sting) ), And the data in the hit state has poor reliability.

難しい状況にある。As described above, in the test of a wind tunnel test model equipped with a conventional interpolation type balance, as described above, when the model is inclined and the support portion is deformed, the end of the model and the support portion are connected to each other. Conventionally, there is no means for detecting this hit, and the data in the hit state is poor in reliability. Therefore, in the conventional wind tunnel test, if there is a discontinuity in the measurement data, it is difficult to determine whether the discontinuity is caused by a hit or has aerodynamic characteristics.

モニタすることで当たりが判別できる。A metal wind tunnel test model is generally higher in rigidity than a support portion composed of an interpolation type balance and a sting, so that it tilts due to the deflection of the sting during the action of aerodynamic force, and hits at the rear end of the model and the sting. In the present invention, a hit detecting device is wrapped around the sting in a range where the hit occurs, and the hit state can be detected. That is, in the hit detection device, two terminal plates are arranged at a predetermined interval, and connected to a power source such as a battery. The terminal plate is plate-shaped, and is configured by, for example, two strip-shaped thin copper plates facing each other with a small gap therebetween. When a metal wind tunnel test model comes into contact with such a terminal plate, the gap between the terminal plates is short-circuited by the model, a current flows through the circuit, and a hit can be determined by monitoring this current.

If the gap between the terminals is short-circuited by contact with the terminals 1 and 22, a current flows from the battery 23 via the resistor 24, and the battery can serve as a switch to inform the experimenter, and the hit of the model 1 can be easily detected. it can.

生する。この状態を図４，図５で示す。In general, the metal wind tunnel test model 1 is higher in rigidity than the support portion (combination of the interpolation type balance 2 and the sting 4), and is inclined at the deflection angle at the tip of the support portion during the aerodynamic action. A hit occurs between the rear end 1a and the sting 4. This state is shown in FIGS.

The front end of the model 1 is tilted downward, and the lower side of the inner peripheral end of the rear end 1a of the model 1 is in contact with the support 11.

As shown in FIG. 1, the detection terminal 3 is wound around and bonded to the entire periphery of the sting 4. As shown in FIG. 3, the hit detection terminal 3 is wired and guided into a measurement room, and the presence or absence of a short-circuit current is monitored to detect the hit. If the hitting direction is clear, the hit detection terminal 3 may be partially bonded instead of the entire periphery of the sting 4. Further, when performing the ventilation test, it is preferable to press the rear end of the model 1 by hand before the test, and to perform the ventilation test after confirming that the switching of the hit detection terminal 3 is performed reliably.

象が生じているかも知れず、正確な判断が難しかった。When there is no hit detection terminal as in the prior art, an estimated aerodynamic force acting on the wind tunnel test model 1 is loaded with a weight, and an area where the model 1 is not hit between the rear end 1a and the sting 4 is applied. Need to figure out. However, since the estimation is difficult, the wind tunnel test is performed. Therefore, a sufficiently satisfactory result cannot be obtained by the test for grasping the area that does not hit beforehand. In this case, the output voltage of the interpolation balance 2 is monitored, and if there is a discontinuity point, it is estimated that the model 1 and the sting 4 are in contact with each other, and the data thereafter is determined to be unreliable. However, it was possible that an aerodynamic discontinuity had occurred, making accurate judgment difficult.

る。When the hit detection terminal 3 is provided as in this embodiment, it is not necessary to grasp the hit area outside the wind tunnel in advance as described above. In addition, it is preferable that the structure between the model 1 and the sting 4 has a structure in which a maximum gap is secured in order to increase a region where the gap does not contact. In addition, the experimenter only has to press the model 1 by hand before the ventilation test and confirm that the switching of the hit detection terminal 3 has been performed reliably. As in the conventional case, the output result from the interpolation type balance 2 is sufficient. This eliminates the need to consider whether a hit has occurred.
