起伏运动

起伏运动,或称周期运动。在这种状态下飞机的机首会因为空气阻力的关系自然地开始上扬导致飞机爬升,直到角度过大之后因为推力不足速度逐渐降低,最后导致机翼升力不足接近失速,机首突然剧烈地向下开始俯冲,并在俯冲的过程中增加空速;直到速度增加到一个程度机翼能够产生足够的上浮力之后,才有办法将下坠的飞机拉回,并开始进入下一次的上扬爬升阶段,重复循环。通常发生在液压系统损坏,导致各翼面的控制功能失效时发生。

Phugoid 起伏运动

A diagrammatic representation of a fixed-wing airplane in phugoid

A phugoid or fugoid /ˈfjuːɡɔɪd/ is an aircraft motion where the vehicle pitches up and climbs, and then pitches down and descends, accompanied by speeding up and slowing down as it goes "uphill" and "downhill." This is one of the basic flight dynamics modes of an aircraft (others include short period, dutch roll, and spiral divergence), and a classic example of a negative feedback system.
