Best glide speed -airspeed at which a glider achieves best glide ratio.

最佳滑翔速度—滑翔机获得最佳滑翔比的空速。

Then they popped the fish into a wind tunnel to calculate their lift-to-drag ratios, sometimes called the glide ratio.

之后，将其放入风洞以计算升阻比，有时也被称为滑翔比。

Define the projected ratio (0.8), while the rope length has been fixed, smaller is projected ratio and more solid is the span. But the disadvantage is smaller the glide ratio.

确定投影比(0.8)，在绳索长度一定的情况下，投影比越小，展向刚性越好，但是同时滑翔比越小。

And the higher the ratio, the farther the aircraft will glide.

升阻比越高，飞机就能飞得更远。
