翼伞

与 翼伞 相关的网络例句 [注:此内容来源于网络,仅供参考]

By deflecting the air downward with the wing we create an upward force of equal magnitude on the wing.

靠著弯曲伞翼下缘的空气,我们制造了一股强度相当的向上的升力於伞翼上。

PARAGLIDER : A hang glider with no rigid primary structure.

飞行伞:一种没有硬翼基层结构之滑翔翼。

In real accidents one drops at relatively low speeds, often less than 10 m/s, because the broken hang glider or collapsed paraglider greatly slow the descent. Rapid deployment of an emergency parachute is indispensable especially for these low speeds.

在实际的事故当中,通常都是飞行员以一个相对较低的速度下坠,通常是低于10米每秒,这是因为坏掉的三角翼或者已经塌陷的主伞大大降低了下坠速度,所以备份伞必须要在这种低速情况下有效迅速的打开。

In a stabilised turn, the paraglider is the aircraft with the record of the smallest turning circle, as shown in figure 4 comparing paraglider, hang-glider and sailplane.

在一个稳定的盘旋中,滑翔伞保持了航空器的最小盘旋半径的记录,图四是滑翔伞同悬挂滑翔机和固定翼滑翔机的比较

Most pilots know the collapse-victim's mantra:"Steer, then Clear." This is meant to help you prioritize your actions: don't focus on reinflating the collapsed side until you've regained steering control of the inflated flying side, and avoided a collision.

大多数飞行员都知道这样一句折翼受害者们总结出来的&咒语&:&驾驶好你的伞,一切会好起来的&(Steer, then Clear),意在帮助你对自己的行动排出优先次序:不要把注意力全集中到使塌陷的翼端重新充气,而是首先设法重新控制好充气良好的未塌陷端,并且避免与其他飞行员碰撞。

Resistance of the wing, lines and pilot as solid bodies blocking the airflow.

伞翼,伞绳和飞行员像固体般堵塞气流产生的阻抗。

They should have extensive experience of international hang gliding, paragliding or other FAI competitions and at least one steward should have experience of paragliding accuracy.

他们应该有广泛的国际滑翔翼、飞行伞或其他 FAI 比赛经验,且至少应该有一个筹办人有飞行伞运动准确性之经验。

Example: Turning right, the right tip of the wing goes down and the left side is goes up, thus we rotate about an axis through the center of the wing.

向右旋时,右侧的翼端会向下沈,左侧的翼端则会向上升,因此我们会沿著伞翼中心的轴线旋动。

This speed relates to the trim angle of attack and it is the flying condition a wing will return to when the pilot releases the controls in smooth air.

此时的伞速会与攻角的调整变的相关连,而这就如同飞行员在平顺的空中方开双手时的伞翼一样。

The helicopter is nothing more than a controlled flat spin (spinning the glider at stall point, very low speed). The wing rotates along the center of the glider while the pilot is straight below the glider. During the maneuver the glider acts like a helicopter. The vertical speed is very low, usually somewhere between -1.3 and -2.0

直升机其实就是一种处于可控状态的水平螺旋--即在非常低的速度下,失速速度下的spin;伞以自身的立轴为轴心旋转,而飞行员处于伞的正下方一起旋转;在动作中,伞看起来像直升机的旋翼一样转动,故得名:直升机;该动作的垂直速度非常低,大约为在1.3米/秒到2米/秒之间。
