美国国家航空航天局(NASA)的研究人员计划开发一种能够使飞机机翼在飞行过程中自由折叠的技术,以提高飞机的飞行效率和能力。NASA将这种机翼称为翼展方向自适应机翼(SAW)。这种可折叠机翼能够在飞行过程中减少或消除飞机在飞行过程中对垂
Researchers at NASA plan to develop a technology that will allow aircraft wings to fold freely during flight to increase aircraft flight efficiency and capabilities. NASA calls this wing a Wingspread Adaptive Wing (SAW). This foldable wing can reduce or eliminate the aircraft during the flight on the vertical
