Stall----

The generation of lift requires that the airflow remains relatively smooth and oderly as it passes over the wing. However as the angle of attack increases, the smooth flow of air gives way to less oderly flow until at a particular angle, called the stalling angle, the airflow breaks down into a chaotic tumbling producing the condition known as the stall.

A SPIN(按我的理解,就应该是螺旋了吧?)

After the aircraft has stalled, a wing drops.

the dropping wing suffers a further increase in angle of attack which worsens the stall.

the loss of lift causes the dropping wing to continue to drop, producing a roll.

the increased drag pulls the dropping wing back, producing a yaw.

This continuous post-stall rolling and yawing is called a spin.

To recover the poilt must check that the throttle is fully closed, apply rudder opposite to the direction of spin to slow down th yaw, and lower the nose to reduce the angle of attack and unstall the wings.

如资料所说,收光油门,反向蹬舵,推杆,待到姿态稳定后再加油门拉杆。

这个“过失速”应该是行家,最有发言权,给他发消息,让他来说说。

还有个问题想请教“过失速”,初教机练习失速,收油门,拉杆抬头到40度,等待失速,然后飞机侧偏进入的状态(这个感觉最有趣,因为事先不会知道到底往那边偏)是否属于“螺旋”呢?

先谢谢了。
