【発明の詳細な説明】 ［産業上の利用分野〕 本発明は宣伝等に利用される気球に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to balloons used for advertising, etc.
従来の気球は、表面が滑らかな状態のものが使用されて
いた。Traditional balloons used had smooth surfaces.
〔発明が解決しようとする課題）
第８図に示すような従来の球形の気球１１は、図のない

る。[Problems to be Solved by the Invention] A conventional spherical balloon 11 as shown in FIG. 8 has a problem because it is moored with a cable 12 directly upward from the ground 13 as shown in FIG. However, if the wind is strong, the tree 1 will be blown away by the wind 10 as shown in Figure 9.
In the worst case scenario, the balloon 11 may explode, causing a social problem that could lead to a disaster.

１８が破裂する事故となり、災害をもたらす社会問題と
なる。この円筒の前後を整形した気球１８は、前記の球
形の気球１１よりも、長手方向（前後方向）に長く大き
いので、この気球Ｉ８の方が事故を起こしやすい。In addition, when there is no wind, as shown in Fig. 10, when there is no wind, a balloon with a cylindrical shape (shaped at the front and back) as shown in Fig. 10 is used.
There is no problem if the tree is moored at 9, but if the wind is strong, the tree 14 may be blown away by the wind 10 as shown in Figure 11.
If the balloon 18 gets caught in the electric wire 15 or the utility pole 16 or hits the building 17, and in the worst case scenario, the balloon 18 will explode, which will become a social problem that will lead to a disaster. The balloon 18, which has a cylindrical shape at the front and rear, is longer and larger in the longitudinal direction (back and forth direction) than the spherical balloon 11, so the balloon I8 is more likely to cause an accident.
また従来の気球においては、気球の後方に活発な剥離渦
２２が発生し、これが気球を振動させ、不安定、不安全
な状態となることがあった。Furthermore, in conventional balloons, active separation vortices 22 are generated at the rear of the balloon, which causes the balloon to vibrate, resulting in an unstable and unsafe condition.
この発明は、従来のものがもつ上記のような問題点を解
消し、安全性が高く取扱い容易で、風１０に流されにく
い気球を提供することを目的とする。The present invention aims to solve the above-mentioned problems of the conventional balloons, and to provide a balloon that is highly safe, easy to handle, and difficult to be blown away by the wind 10.
本発明は、前記従来の課題を解決するために、表面に凹
凸を有することを特徴とする気球を提案するものである

向上する。[Function] In the present invention, by providing unevenness on the surface of the balloon, the flow around the balloon is changed, the separation area behind the balloon is reduced, the air resistance is reduced, and the amount blown away by the wind is reduced. Since active separation vortices are suppressed to create gentle separation vortices, vibrations are reduced, the stability of the balloon is increased, and safety is improved.

る。FIG. 6 is a side view showing the flow around a sphere 6 with a smooth surface. If wind 10 is flowing from left to right,
The flow separates near directly above or directly below the ball 6 with a smooth surface and separates at a separation point 20), and a wide separation region 7 occurs behind the ball 6 with a smooth surface, resulting in large air resistance. There is a strong flow of wind 10. In addition, an active separation vortex 22 is generated, causing the ball 6, which has a smooth surface, to vibrate unstablely, causing stability and safety problems.

0 is flowing from left to right, compared to the flow around the sphere 6 with a smooth surface, the position where separation occurs moves backward, and separation occurs at the separation point 21. Therefore, a narrow separation area 9 is generated behind the ball 8 having a convex or concave surface, and the air resistance is much smaller than that of the ball 6 with a smooth surface, and the amount of air flow is significantly reduced. . Further, behind the ball 8 having a convex or concave surface, only a gentle separation vortex 23 is generated, and there is little vibration.
Stability and safety have been improved and it can be operated without problems.
