大头大头,下雨不愁。你有雨伞,我有大头。一直以来,雨天没带伞总是令小头君很忧伤,而伞的“金属杆+防水布”的传统结构也降低了男神们的时尚指数。如今福音到,我——空气雨伞——利用气流来帮助人们避雨,华丽丽地出现了。流动的空气能够改变物体的运动轨迹。空气运动速度越快,它的能量也就越强。而喷射的气流甚至可以将一些物体隔离开来。中国北京航空航天大学与南京航空航天大学的设计团队就想出利用气流,形成一把看不见的雨伞来避免人们被雨淋湿。于是我——空气雨伞应运而生,只有一个伞柄,看上去就像是一根魔术师手中把玩的棍子。 Big head, rain worry. You have an umbrella, I have a big head. Traditionally, the rainy day without umbrellas always makes Koizumi Jun sad, while the traditional structure of the umbrella “metal rod + tarpaulin” also reduces the men’s fashion index. Now, the Gospel comes, I - the air umbrella - the use of airstream to help people shelter, gorgeous appeared. Flowing air can change the trajectory of the object. The faster the air moves, the greater its energy. The jet of air and even some objects can be isolated. China’s Beihang University and Nanjing University of Aeronautics and Astronautics design team came up with the use of airflow to form an invisible umbrella to prevent people from getting wet. So I - air umbrella came into being, with only one umbrella handle, looks like a magician stick in the hands of playing.
