Abstract
Description
[0044] 骨格16および表皮18の開示される配置および設計は、任意のタイプの乗物ボディ10に関連して使用され得る。たとえば、骨格16および表皮18は、飛行機の機体、ドローンの機体、自動車の車体、船の船体、または軽量低コスト高性能が重要である任意の他のタイプの乗物ボディに関連して使用され得る。乗物ボディ10は、表皮18を骨格16に固定し、かつ/または乗物ボディ10の構成要素を互いに固定するのに必要なファスナの個数の減少に起因して、軽量かつ低コストになる可能性がある。さらに、乗物ボディ10は、骨格16と表皮18との両方を作るのに使用される複合材料の使用により軽量で行うことができる。高性能は、特定の繊維および樹脂が骨格16内および表皮18内で使用され、配置される独自の方法で実現され得る。
