本願は新規な構成を有するラジオコントロールヘリコプ
タ−の回転翼の製法を提供しようとするものである。DETAILED DESCRIPTION OF THE INVENTION The present application provides a method for manufacturing a rotor blade for a radio control helicopter having a novel configuration.
従来、提供されているこの種のものにあっては、バルサ
材などをコアー状にはゆ合せた素材をもって製造されて
いる。しかし、このものは回転翼であるところから複雑
な力が加わるが、かかる素材のものではその耐久性に問
題があるほか、木材であるところから狂が発生したり、
また、製造時においても所望する形状に製造することも
困難であった。Conventionally available products of this type are manufactured using a core material made of balsa wood or the like. However, since this is a rotary blade, complex forces are applied to it, and if it is made of such materials, there are problems with its durability, and since it is made of wood, it may become distorted.
Furthermore, it was also difficult to manufacture into a desired shape during manufacturing.
本願はかかる問題を充分解決しようとするもので、以下
図面を参照しながら、そのｌ実施例の詳細を説明する。The present application attempts to fully solve this problem, and details of an embodiment thereof will be described below with reference to the drawings.
１は本発明の方法で得た回転翼である。そこで、その製

皮６で覆う工程については第４図の如く袋状の外皮に芯
体を挿入するとよい。1 is a rotor blade obtained by the method of the present invention. Therefore, the manufacturing method is configured as follows. A core body 2 is made of a rotary blade shape made of wood with balsa wood or other materials pasted together in a core shape, and is covered with an outer skin 3 made of carbon fiber woven in a bias shape and formed into a bag shape. A liquid resin is applied to the surface, cured while correcting the shape using a mating mold 4, and then removed from the mold. In this case, in the step of covering the core body 2 with the outer skin 6, it is preferable to insert the core body into a bag-shaped outer skin as shown in FIG.
また、合せ型４については第５図の如く上下の型体４Ａ

該回転翼の強度を適宜調整することができる。Also, regarding the mating mold 4, as shown in Fig. 5, the upper and lower mold bodies 4A
, 4B, and recesses 4A', 4B' corresponding to the outer circumferential surfaces of the rotor blades are carved in the mold bodies 4A, 4B. The shapes of the recessed portions 4A' and 4B' are formed in consideration of the slightly twisted shape of the rotary blade. Further, referring to FIG. 1, the strength of the rotor blade can be adjusted as appropriate by making the angle θ of 3 degrees in the longitudinal direction of the carbon fibers acute or obtuse with respect to 1 degree in the longitudinal direction of the rotor blade 1. Can be done.
本願のものは上述の如く構成されているから、Ａ０合せ
型で矯正しながら製造できるから、正確な回転翼を容易
かつ確実に得ることができる。Since the structure of the present invention is constructed as described above, it can be manufactured using the A0 matching mold while being corrected, so that an accurate rotor blade can be obtained easily and reliably.
Ｂ、外皮３．液体樹脂で形成されているから、芯体を従
