Description of the Related Art Among the development tests of aircraft, there is a wind tunnel model that uses a wind tunnel model manufactured in a similar manner to an actual aircraft to obtain the characteristics of the actual aircraft. In the normal wind tunnel test, as shown in FIG. 5, the aerodynamic force generated in the wind tunnel model 53 connected to the tip portion 56 of the sting 51 via the balance 52 is set by the balance 52 in the X-axis model 53. , Y-axis, Z-axis force,
And measuring the rotational moment around each of these axes,
I try to find the actual machine characteristics. Also, Sting 5

The wind tunnel model 53 is installed in the wind tunnel measurement unit, and the wind tunnel device 60 connected to the root portion 55 at the rear end is moved up and down, whereby the angle of attack α of the wind tunnel model 53 with respect to the air flow F flowing in the axial direction of the wind tunnel is increased. I am trying to change it.

る。FIG. 6 shows the whole of a conventional circular sting 51 which has been conventionally used. However, depending on the purpose of the wind tunnel test, there is a gap between the tip portion 56 and the root portion 55 as shown in FIG. A flat plate sting 54, which is flat, may be used. That is, the sting is for the wind tunnel model 5
3 is installed in the wind tunnel measurement unit, and the wind tunnel model 53 for the air flow F
In addition to changing the angle of attack α of the wind tunnel model 53, the flow behind the wind tunnel model 53 (the wake) is rectified into a flow similar to the actual machine, and the flow around the wind tunnel model 53 is disturbed by the turbulence of the wake and the characteristics of the actual machine It is also intended to prevent an aerodynamic force different from that from being generated in the wind tunnel model 53. For this reason, the shape and size behind the sting tip portion 56 must be a shape and size that can rectify the wake, in addition to the requirement from the standpoint of strength.

Since 1,54 are made by integral molding of steel material, the structural damping factor is as low as 1% or less, and the weight is large, and the natural frequency of the wind tunnel model attached to the tip is It is small. Therefore, when the wind tunnel model 53 is set to a large angle of attack α with respect to the air flow F, and the wind tunnel model 53 becomes aerodynamically unstable and vibration occurs,
The support system including the stings 51 and 54 has no vibration damping force, and the vibration of the wind tunnel model 53 is caused by the sting 5.
Since the vibration is performed at a frequency close to the natural frequency of the wind tunnel model 53 attached to the tips of the wind tunnel models 1, 54, the vibration of the wind tunnel model 53 may diverge and the wind tunnel test may become impossible.

When performing a wind tunnel test using such a wind tunnel model, it is often the case that the vibration cannot be suppressed by the conventional support by Sting described above.

The wind tunnel test may not be possible.
