如何叠一个打破世界纪录的纸飞机

How to Make a World-Record-Breaking Paper Airplane

如果你想要叠一个世界上飞的最远的纸飞机
So you want to make the world’s farthest-travelingpaper airplane.
你在学校里学到的技巧可帮不了你哦
The technique you learned in school won’tcut it.
叠纸飞机有四大要点:
When making a paper plane, there are fourthings to consider: No.
第一:纸质想让纸飞机飞的距离够远 你需要用尽可能重的纸
1: The PaperWhen you looking for distance you want your paper as heavy as possible
按照一令(500张)的重量计量
Paper is measured in the weight of a ream—500pages.
美国普通的复印纸为20—24磅
The average copier paper in the U.S. is 20-24pound stock.
吉尼斯世界纪录允许使用
Guinness World Record rules allow us to use paper that weighs
最重100克/平方米
up to 100 grams per square meter,
即26.4磅的纸做纸飞机
or about 26.4 pounds.
通常这个重量的纸规格为
Paper that heavy usually comes
A4——一种在美国不常用的国际纸张规格
in A4—an international paper size not commonly used in the U.S.
John Collins为目前世界纸飞机记录保持者
John Collins, the paper plane designer whocurrently holds the world-record,
他说 要用复印过的纸来做纸飞机
says you want paper that’s been photocopied on.
复印机的热处理工序让纸张变得坚硬
The heat process from the photocopy machinestiffens the paper.
复印用的墨水并不算真正的墨水
And the ink is not actually ink,
而是一层超细的塑料
it’s a microfine layer of plastic.
这两者——加热和塑料 使得纸张能够把折痕保持住
Those two things—the heat and the plastic—help the paper hold a crease.
所以 要用回收再造的纸
Use something that’s in the recycle bin,you know?
还有就是 不要用打印过的纸
And don’t use something that’s been printed on.
因为那种墨水会破坏纸张的纤维
That ink will hurt the fibers of the paper.
如果你用再生纸
You want something that’s been photocopied
要用复印过的纸
onto if you’re using a piece of recycled papers. No.
第二:力和重心
2: Forces andCenter of Gravity
对任何纸飞机来说
For any paper airplane,
在飞行中你都需要处理好两种力:升力
you’ll have to deal with two major forces during your flight: lift,
或者叫向上力 和阻力 或者叫向后力
or upward force, and drag, or backward force.
你的飞机要起飞 就需要产生的升力大于阻力
Your plane needs to generate more lift than drag to go up.
如果阻力大于产生的升力 飞机就会掉下来
When more drag is generated thanlift, the plane falls.
你需要设计出
You have to engineer
一种方法让飞机通过加速来抵消阻力
in a way for the plane to gain speed to counteract drag.
在机尾处折出向上的弧度
You put a small bend at the back of the plane, upward,
这样一来 当飞机加速
so that when the plane has gained
到位后 足够多的气流从
sufficient speed, there’s enough air bouncing
上弧位置弹回 把机尾
off of that upward bend to deflect the tail
拉低 机头拉高
back down and that pulls the nose
从而达到水平位置
up and now it’s level again.
当你在设计飞机的时候
When designing your aerial vehicle,
要确保机翼是向上折的
you’ll want to make sure the wings are bent upwards.
这叫做 正二面角
This is called a positive dihedral angle,
它会在飞机开始摇摆时 起到修正作用
and helps the plane to correct itself if it starts to sway.
当一侧机翼下沉太多时
When one wing dips too low,
正二面角会产生额外的升力 把飞机拉回重心
it produces extra lift and the plane will return to its center of gravity. No.
第三:地点!地点!地点!
3: Location! Location! Location!
想找到一个
It’s not easy to find a
能打破该世界记录的场所并不容易
space big enough to break this world record.
Collins那打破世界纪录的飞机 是由四分卫Joe Ayoob
Collins’ world-record breaking airplanewas thrown by quarterback Joe Ayoob
在加州Sacramento的McClellan空军基地抛出去的
at the McClellan Air Force Base in Sacramento, CA.
并且Collins还说天气情况必须要完美才行
And Collins says you need the perfect weather conditions.
投掷结果最好的那些日子基本上温度在52-62华氏度
All of our best throwing days were 52 to 62 degrees,
湿度在25-30%
25-30 % humidity.
如果空气厚度不对
If the air thickness is wrong,
或者机翼没有坚硬到能够驾驭
or if the wings aren’t stiff enough to take advantage of the
空气质量 飞机通常会在最后三分之一程力竭
air quality, the plane tends to die in thatlast third.
你需要百分百的稳定
You want perfectly stable. No.
第四:投掷
4: The Throw
棒球投手的投掷动作
The best form isn’t like a pitcher in baseball,
甚至NFL里四分卫的投掷动作都不是最合适的的
or even like an NFL quarterback.
最合适的更像标枪投手的动作
It’s like a javelin thrower.
Joe的优点在于 他有自己的方式
The great thing about Joe is that he had a way,
和理解 去改变他的投掷方法
a knowledge, of changing his throw to
来配合该运动 这对于研究
match the sport that really was invaluablein looking at
如何用最合适的方法投掷纸飞机来说是无价的
how to throw the paper airplane the best way.
我们一起合作了大约18个月 整个期间他都在
We worked together for about 18 months and he was working
不知疲倦地练习他的投掷方式
on his throwing technique the whole time.
让我们总结一下:用100GSM的A4纸
To summarize: Find 100 GSM A4 paper,
设计飞机时找准重心
design your plane with the proper center of gravity
和升力的中心
and center of lift,
在合适的地点 合适的条件下 用合适的姿势投掷飞机 恭喜你
and throw it the right way in the right place under the right conditions. Congrats,
现在你是新的纸飞机世界纪录保持者啦
you’re now a world record holder.
