“Most aerodynamic things take off at very gradual angles, but this has a very striking, very powerful lift angle, ” Swartzlander says.

Swartzlander says：“大多数空气动力装置起飞的角度很平缓；而这样的装置起飞时角度变化非常剧烈，非常惊人。”

And what is striking, really remarkable, that this is independent of the amplitude, and it's also independent of this Angle phi, this phase Angle.

令人惊讶的是，非常值得注意的，这个和振幅，没有关系，也和角度，没有关系，和相位角无关。

So the control system should be started under large Angle of flow in order to avoiding striking the cylinder.

启动电流随导通角的增大而减小，控制系统应以大导通角启动，可防止撞缸现象。
