科学60秒 听力 2016年4月合集

The sensor sits in the knob of the company's so-called Smart Bat and uses two accelerometers and a three-axis gyroscope to measure bat speed, hand speed, attack angle and other factors.

该传感器位于这家公司智能球棒的把手处,其中的2个加速器及一个3轴陀螺仪能够对球棒速度、手速、打击角度等其他因素进行测量。

自然杂志:科技

We use laser projection methods to understand how to create wings and the attack angles and the number of wings and the geometries and the weight distributions to fully optimise the way that these structures are flying.

约翰:我们使用激光投影方法来了解如何创建机翼和攻角以及机翼的数量和几何形状以及重量分布,以充分优化这些结构的飞行方式。

攻角 Angle of attack

(重定向自Attack Angle)
图中之α为此翼剖面之攻角
Platform Angle of Attack
A typical lift coefficient curve.

攻角英语:Angle of attack,缩写为AOA,常用希腊字母α表示)为一空气动力学名词,为机翼之翼弦与自由流(或是相对风流的方向)之夹角;如为飞机攻角,定义则为机轴对相对风流之夹角。当机翼向攻角,向则为攻角。

它有可能与俯仰角搞混。俯仰角是指翼弦与飞行器俯仰之夹角,而攻角是指与自由流之夹角。

机翼要有升力,则必须要有攻角或是弧度(camber)。有弧度的机翼,其零升力攻角不为零,也就是在攻角0度时,有弧线的机翼就有升力。而对称翼不具弧线,所以在攻角0度时没有升力,必须要有攻角,机翼才能提供升力。

Angle of attack 攻角

(重定向自Attack Angle)
Platform Angle of Attack
A typical lift coefficient curve.
图中之α为此翼剖面之攻角

In fluid dynamics, angle of attack (AOA, or \alpha (Greek letter alpha)) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air.
