この考案は、チヤフロールの構造に関するもの
である。[Detailed Description of the Invention] This invention relates to the structure of a tire roll.
従来、この種のものとしては、第１図に示すも
のがあつた。 Conventionally, there has been a device of this type as shown in FIG.
図において、１１は樹脂製フイルム、１２は短
冊形に形成された平板状のチヤフ素子、１３はチ
ヤフロールである。チヤフ素子１２は樹脂製フイ
ルム１１の間に適当に並べロール状にまきとりチ
ヤフロール１３として保管される。第２図は平板
状のチヤフ素子１２の拡大図である。 In the figure, 11 is a resin film, 12 is a flat chaff element formed in a rectangular shape, and 13 is a chaff roll. The chaff elements 12 are appropriately arranged between the resin films 11 and wound into a roll to be stored as a chaff roll 13. FIG. 2 is an enlarged view of the flat plate-shaped chaff element 12.
次に動作について説明する。 Next, the operation will be explained.
チヤフロール１３を解いてゆくと樹脂製フイル
ム１１の間からチヤフ素子１２が空中に放出され
空間に拡散してレーダ波の反射体として使用され
る。 When the chaff roll 13 is unwound, the chaff element 12 is released into the air from between the resin films 11, diffused into space, and used as a radar wave reflector.
従来のチヤフロールは以上のように構成されて
いるが、チヤフ素子が短冊形に形成されているた
め、ロールから放出された後のチヤフ素子は風、
風圧等でその長辺（長手）方向に曲がり、お互い
にからみ合う。このため、拡散性が悪く、レーダ
有効断面積が小さいという欠点があつた。 The conventional chaff roll is constructed as described above, but since the chaff element is formed into a rectangular shape, the chaff element after being released from the roll is exposed to wind,
Due to wind pressure, etc., they bend in the direction of their long sides and become entangled with each other. For this reason, it had the drawbacks of poor diffusivity and a small radar effective cross-sectional area.
この考案は、上記のような従来のものの欠点を
除去するためになされたものである。 This invention was made in order to eliminate the drawbacks of the conventional ones as described above.
以下、この考案の一実施例を図について説明す

ルム２１の間に折り曲げたチヤフ素子２２を適当
に配列してまきこみ、チヤフロール２３を構成す
る。 An embodiment of this invention will be described below with reference to the drawings. In FIG. 3, 21 is a resin film;
2 is a chaff element bent into a chevron shape in its short side (width) direction, and 23 is a chaff roll. FIG. 4 is an enlarged view of the folded chaff element. A chaff roll 23 is constructed by appropriately arranging and wrapping folded chaff elements 22 between resin films 21.
次に動作について説明する。樹脂製フイルム２
１の間から放出されたチヤフ素子２２は空中に放
出され空間に拡散する。チヤフ素子２２として折
曲げた形状のものを使用しているので、チヤフ素

好な拡散性をもつ。このため大量のチヤフ素子の
散布が可能になり、その結果、大きなレーダ有効
断面積を得ることができる。 Next, the operation will be explained. Resin film 2
The chaff element 22 released from between the holes 1 and 1 is released into the air and diffused into the space. Since a bent shape is used as the chaff element 22, the chaff elements do not bend and become entangled with each other, so that good diffusivity is achieved. Therefore, it is possible to scatter a large amount of chaff elements, and as a result, a large effective radar cross-sectional area can be obtained.
なお、上記実施例では、チヤフ素子をロール式
にまきとつたものを示したが、チヤフ素子を箱、
袋から空中に散布する場合についても同様の効果
を奏する。 In addition, in the above embodiment, the chaff element was rolled up in a roll type, but the chaff element was rolled up in a box,
A similar effect can be achieved when spraying from a bag into the air.
以上のように、この考案によれば、チヤフロー
ルのチヤフ素子をその短辺方向に折曲げたものを
使用することにより、レーダ有効断面積の大きな
チヤフ雲を得ることができる効果がある。 As described above, according to this invention, by using a chaff element of a chaff roll that is bent in its short side direction, it is possible to obtain a chaff cloud having a large effective radar cross-sectional area.
