身体停留在半空,俯瞰地面,在云朵里做梦,从滑翔伞.到热气球,再到飞机.人类掌控蓝天的技术越来越先进.飞上蓝天越来越自由,我们不禁要问:究竟有多少种方式飞上天空?滑翔伞:伞衣内设有气囊,充气后,滑翔伞的前沿会有棱角,飞行时将相对的气流由翼面上下分别引开流动,靠着空气动力产生速度而前进。 The body stays in mid-air, overlooking the ground, dreaming in the clouds, from paragliding, to hot-air balloons, to planes. As humans become more and more adept at controlling the blue sky, as we fly more and more freely into the blue sky, we ask: How many ways to fly to the sky? Paragliding: Umbrella equipped with airbags, inflatable, the front of the paragliding will have edges and corners, the flight will be relative to the air flow from the airfoil up and down, respectively, to open the flow, relying on aerodynamic speed go ahead.
