|
| So we looked at the birds, and we tried to make a model that is powerful ultralight , and it must have excellent aerodynamic qualities that would fly by its own and only by flapping its wings. |

|
| So what would be better [than] to use the Herring Gull , in its freedom, circling and swooping over the sea, and [to] use this as a role model ? |
那么以什么鸟形建模好呢？ 银鸥,这种鸟可以自由地 在海面上空盘旋和俯冲, 我们选择以此建模。 |

|
| So maybe we'll try it once to fly a SmartBird. |
我们来尝试一次 放飞智能鸟吧。 |
| Thank you. |
谢谢。 |
| (Applause) |
（鼓掌） |
| (Applause) |
（鼓掌） |
| (Applause) |
（鼓掌） |
| So we can now look at the SmartBird. |
现在我们可以 一睹智能鸟了。 |
| So here is one without a skin. |
这里是一个没有外壳的。 |
| We have a wingspan of about two meters. |
它的翼展约为两米。 |
|
wingspan:n.翼展;翼幅;
|
| The length is one meter and six, and the weight, it is only 450 grams. |
体长为一米六。 而体重 只有450克。 |
| And it is all out of carbon fiber . |
它整体都是碳纤维材料做的。 |

|
| In the middle we have a motor, and we also have a gear in it. |

|
| And if we now beat up and down ... |
如果让这翅膀上下拍打的话 |
| we have the possibility to fly like a bird. |

| So if you go down, you have the large area of propulsion . |

propulsion:n.推进;推进力;
|
| And if you go up, the wings are not that large, and it is easier to get up. |

|
| Also, we see how we measure the aerodynamic efficiency . |
同时,我们也知道 如何测算出它的空气动力效能。 |

|
| We had knowledge about the electromechanical efficiency and then we can calculate the aerodynamic efficiency. |
我们必须掌握 电机效率 然后就能计算出 空气动力效能。 |
|
electromechanical:adj.电机的;电机学的;
|
| So therefore, it rises up from passive torsion to active torsion, from 30 percent up to 80 percent. |
所以, 从被动扭曲力转化为主动扭曲力,它的效能从 30%提高到 80%。 |
|
passive:adj.被动的,消极的;被动语态的;n.被动语态; torsion:n.扭转,扭曲;转矩,[力]扭力;
|
| Next thing we have to do, we have to control and regulate the whole structure. |
下一件我们要做的, 就是要控制和调整 整个结构。 |
|
regulate:v.调节;控制;
|
| Only if you control and regulate it, you will get that aerodynamic efficiency. |
只有控制和调整好它 才能得到预期的空气动力效能。 |
| So the overall consumption of energy is about 25 watts at takeoff and 16 to 18 watts in flight. |
所以整体能量消耗 大概是起飞25瓦 飞行是16到18瓦特。 |
|
overall:v.全部; n.外套; adj.全面的; consumption:n.消费;消耗;肺痨; watts:n.瓦特(功率单位); takeoff:起飞;开始;起跳;起跳的,起飞的;
