起落架

AN-225巨型起落架
波音747客机降落前释放主起落架
DC-3是采用后三点式起落架

起落架是航空器下部用于起飞、降落或者在地面(或水面)滑行时支撑航空器,并且用于地面(或水面)移动的附件装置。

目前大部份飞机都是采用前三点式起落架,起落架有一组鼻轮和两组主轮支撑整个飞机,飞机重心位于主轮之前。前三点式起落架比后三点式起落架最大的优点是前者能使飞机处于水平或接近水平的状态,当飞机在地面时不会影响飞行员的视野,喷射发动机所排出的高温废气不会因为飞机不是处于水平状态而直接喷向跑道铺面,对跑道的负面影响较少。

早期的飞机大都是采用后三点式起落架,起落架有两组主轮和一组尾轮支撑整个飞机,飞机重心位于主轮之后。在1940年代以前曾被广泛使用的后三点式起落架,其最大优点是其结构简单,落地时三组机轮可以同时触地。然而后三点式起落架最大的弊病是因为飞机重心位于主轮之后,主轮的高度比尾轮高,因此当飞机在滑行或停泊时在驾驶舱的飞行员会仰望天空,能够看到地面的视野较少,所以起飞时一进入跑道要先左右两个方向转再对正跑道加速起飞,这个进程是让飞行员透过左右转向目视跑道尾端来确认对正跑道,因为后三点式起落架的飞机在对正跑道时,飞行员是看不到的,只有在飞机加速到接近抬头速度(Rotate,Vr),机尾因升力飘起后,飞行员才能看到跑道,且一般风速(强风例外)降落时,在触地前要拉起机头平飘,让三个机轮同时触地,否则触地的刹那,因机尾还是悬空,触地冲击力会使得机头忽然朝上,飞机暂时向上飞起造成弹跳,降落进程比较复杂。此一缺点使二十世纪40年代以后的飞机都改为采用前三点式起落架。

Landing gear is the undercarriage of an aircraft or spacecraft, and is used in both takeoff and landing.

For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheels are typically used but skids, skis, floats or a combination of these and other elements can be deployed depending both on the surface and on whether the craft only operates vertically (VTOL) or is able to taxi along the surface. Faster aircraft usually have retractable undercarriages, which folds away during flight to reduce air resistance or drag.
