The invention discloses a helicopter tail blade manufacturing method, the manufacturing method comprises the specific operation steps of preparation work, mold filling, curing and mold starting, and in the preparation work, a forming mold matched with a helicopter tail blade and a silicon rubber air bag core mold matched with a cavity structure of a composite material blade need to be selected; and after the prepreg layer is laid, mold closing, heating and curing are carried out, pressure relief and mold opening are carried out after curing is completed, and the silicone rubber air bag is taken out through an auxiliary mold opening tool. The helicopter tail rotor blade disclosed by the invention is simple in manufacturing steps and process, and the forming precision is easy to guarantee; in addition, the cavity structure in the composite paddle is formed through the silicone rubber air bag core mold, the silicone rubber air bag core mold is convenient to take out and place, and it can be ensured that the cavity structure can achieve the expected forming effect through the silicone rubber air bag core mold.

    本发明公开了一种直升机尾桨叶的制作方法,该制作方法的具体操作步骤包括准备工作、装模、固化以及启模,其中,在准备工作中需要选取与直升机尾桨叶适配的成型模具和与复合材料桨叶的空腔结构适配的硅橡胶气囊芯模;预浸料层铺完成后进行合模升温固化,固化完成后卸压启模,并通过辅助启模工具将硅橡胶气囊取出。本发明公开的直升机尾桨叶的制作步骤以及工艺简单,并且成型精度易于保证;另外本发明利用硅橡胶气囊芯模对复合材料桨叶中的空腔结构进行成型,硅橡胶气囊芯模取出和放置均比较方便,并且利用硅橡胶气囊芯模能够确保空腔结构能够达到预期的成型效果。
