直升机 Helicopter
（重定向自Helichopper）
直升机是一种由一个或多个水平旋转的旋翼提供向上升力和推进力而进行飞行的航空器。直升机具有大多数固定翼航空器所不具备的垂直升降、悬停、小速度向前或向后飞行的特点。这些特点使得直升机在很多场合大显身手。直升机与固定翼飞机相比，其弱点是速度低、耗油量较高、航程较短。

（重定向自Helichopper）
A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (vertical takeoff and landing) aircraft cannot perform.
