To provide an aircraft frame which has a light-weight strong structure, and can be easily transported and can suppress a storage space.SOLUTION: An aircraft frame 2 comprises a plurality of units 10(10') having a substantially pyramid shape configured from a plurality of tubular members 11, 12(12'). In the unit 10 (10'), end parts of a plurality of bottom side tubular members 11A to 11D (11A' to 11D') are coupled, whereby a pyramid bottom surface B is formed, and lateral side tubular members 12 (12'), of which one ends are connected to the end parts of the bottom side tubular members 11A to 11D (11A' to 11D'), are connected to each other at other ends, whereby a pyramid apex is formed. The plurality of units 10 is connected in a detachable state, the bottom surface B of the pyramid of each unit 10 (10') is located on a substantially same face to form a top face, the apex of the pyramid of each unit 10 (10') is located on a lower side than the top face.SELECTED DRAWING: Figure 1A
【課題】軽量で強固な構造を有するとともに、容易に搬送でき、保管スペースを抑制できる機体フレームを提供することにある。【解決手段】複数の管状部材11’、12(12’)で構成された略角錐形状を有するユニット10(10’)を複数備え、ユニット10(10’)は、複数の底辺管状部材11A~11D(11A’~11D’)の端部が連結されて角錐の底面Bが形成され、底辺管状部材11A~11D(11A’~11D’)の端部に一方の端部が連結された側辺管状部材12(12’)が他方の端部で互いに連結されて角錐の頂点が形成され、複数のユニット10が着脱可能な状態で連結されて、各々のユニット10(10’)の角錐の底面Bが略同一面上に配置されて上面を形成し、各々のユニット10(10’)の角錐の頂点が上面より下側に配置されている機体フレーム2を提供する。【選択図】図1A
