美軍研發(fā)出可變形車輪 可適應95%的地形

The Pentagon has developed a shape-shifting wheel to make life easier for troops travelling over difficult terrain.

近日，五角大樓研發(fā)出了一款可變形車輪，使部隊在險要地形上更容易行進。

A military truck in which the driver can switch the wheels to a more triangular shape and back againhas been demonstrated by the defense advance dresearch projects agency.

國防部高級研究計劃局展示了一輛軍用卡車，駕駛員可以在車里調整車輪，將其變得更像三角形，然后再變回來。

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.

可變形的后輪讓車輛可以抓住較軟的或者光滑的地面，但一旦駛向較硬的地面，它可以在兩秒內變回到更加傳統(tǒng)的圓形。

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.

該創(chuàng)意是“陸地X車輛技術”項目的一部分，這個項目旨在將老舊的軍用悍馬替換成更輕、速度更快且能適應95%的地形的車輛。

As well as changing shape, researchers have also designed a small engine that can fit inside the wheels to boost acceleration and manoeuvrability.

除了變換形狀，研究人員還設計了一款小型發(fā)動機，可以裝在車輪內部，促進加速以及提升機動性。
