The Pentagon has developed a shape-shifting wheel to make life easier for troops travelling over difficult terrain.
近日,五角大楼研发出了一款可变形车轮,使部队在险要地形上更容易行进。
A military truck in which the driver can switch the wheels to a more triangular shape and back again has been demonstrated by the defense advanced research projects agency.
国防部高级研究计划局展示了一辆军用卡车,驾驶员可以在车里调整车轮,将其变得更像三角形,然后再变回来。
The shape-shifting rear wheels give the vehicle track-like grip on soft or slippery terrain, but can be converted back to a more traditional round shape in two seconds for harder surfaces.
可变形的后轮让车辆可以抓住较软的或者光滑的地面,但一旦驶向较硬的地面,它可以在两秒内变回到更加传统的圆形。
The idea is part of a program called ground x-vehicle technologies that aims to replace the aging Humvee with a lighter, faster vehicle that can adapt to 95% of terrains.
该创意是“陆地X车辆技术”项目的一部分,这个项目旨在将老旧的军用悍马替换成更轻、速度更快且能适应95%的地形的车辆。
As well as changing shape, researchers have also designed a small engine that can fit inside the wheels to boost acceleration and manoeuvrability.
除了变换形状,研究人员还设计了一款小型发动机,可以装在车轮内部,促进加速以及提升机动性。
