The invention provides an integrated airfoil structure suitable for an aircraft and the aircraft. The integrated airfoil structure suitable for the aircraft comprises a skin and a dot matrix core layer, a containing space is formed in the skin, and the dot matrix core layer is located in the containing space. The dot matrix core layer is formed by a plurality of dot matrix unit cells in a periodic array mode, and the containing space is filled with the dot matrix unit cells. Preferably, reinforcing ribs are further included, and the reinforcing ribs are arranged on the inner surface of the skin. The reinforcing ribs are used for improving the strength and rigidity of the skin, and the skin and the reinforcing ribs form the reinforcing rib skin. According to the invention, laser near-net forming, selective laser sintering or selective laser melting 3D printing technology is adopted for manufacturing. And the material is GH4049 or GH4099 alloy. The integrated design is adopted, that is, the integrated forming is adopted, the defect that all split bodies in a split structure need to be connected is overcome, rivets, spot welding and diffusion welding do not need to be used, and compared with the diffusion welding, the integrated forming is simple in process and low in cost.
本发明提供了一种适用于飞行器的一体化翼面结构及飞行器。适用于飞行器的一体化翼面结构,包括蒙皮、点阵芯层;蒙皮内设置有容纳空间,点阵芯层位于容纳空间内;点阵芯层由多个点阵单胞周期性阵列而成,多个点阵单胞填充于容纳空间内。优选的,还包括加强筋,在蒙皮内表面设置加强筋;加强筋用于提高蒙皮的强度和刚性,蒙皮与加强筋组成加强筋蒙皮。本发明采用激光近净成型、选区激光烧结或选区激光熔化3D打印技术制造。材料为GH4049或GH4099合金。本发明采用一体化设计,即通过一体成型制成,避免了分体式结构中各分体需要连接的缺陷,无需用到铆钉、点焊以及扩散焊,并且一体成型较扩散焊工艺简单,成本低。
