民航飞机能桶滚吗?
的有关信息介绍如下:
何谓桶滚?请看蓝色的飞行轨迹。这是一个标准的防御桶滚机动。飞机相当于绕着一个虚拟的水平轴做旋转,这个机动过程中有明显的减速效果(此处指水平分量)。而以飞机自身的轴做滚转是不会明显减速的(只有副翼动作没有尾舵动作)。
以下引用自维基百科词条:
A barrel roll is an aerial maneuver in which an
makes a complete
on both its longitudinal and lateral axes, causing it to follow a
path, approximately maintaining its original direction. It is sometimes described as a "combination of a loop and a roll."
The
is kept positive (but not constant) on the object throughout the maneuver, commonly between 2–3 g, and no less than 0.5 g.
这个机动通常见于战斗机,用于回避敌机的机炮和导弹攻击(配合Flares使用)。对于多数的多发飞机,由于基本滚转性能(绕飞机自身轴)就较差,完成桶滚动作就更加困难了。本身桶滚机动是要把升降舵和方向舵同时打满的,某试飞Dash 80时作死的人也许是为了展示这飞机的舵效很好吧。(笑
