人力驱动直升机竞赛:直面困难

Human-Powered Helicopter: Straight Up Difficult | SKUNK BEAR

A structured design is sitting on the edge of what’s strong enough and what’s light enough,
结构设计既要兼顾牢固性和轻量化
taking out the engine is a big challenge to us,
还不能有引擎 这是个巨大的挑战
putting in a human there is what really makes it umm… hard.
再要求能载人 这就更困难了
A team of young engineers from the University of Maryland
一支来自马里兰大学的年轻工程师队伍
is trying to do the impossible.
正在挑战不可能
Conceptually it’s extremely basic, and yet, in practice it’s extremely difficult.
概念上它很简单 却很难付诸实践
Push it! Good! Henry, good! Keep that around there.
加油!很好 亨利!保持好
They’ve spent the last four years building a human powered helicopter
他们花了四年时间来研制这架人力直升机
and now they’re putting it to the test.
现在正在进行测试
These engineering students are chasing
这些工科学生们的目标
the American Helicopter Society’s 250,000 dollars Sikorsky Prize.
是争取美国直升机学会25万美元的西科斯基奖金
Bang bang bang bang…
#邦邦 邦邦 邦邦 邦邦……#
It’s been unclaimed for more than three decades.
这个奖项已经空置三十多年了
They have to build a human powered flying machine
他们需要制作一个人力飞行器
that can hover for a minute and reach a height of three meters
用它在三米的高度悬停一分钟
without drifting out of a ten meter box.
并且不得漂移出10平米的范围
It’s an engineering challenge, it’s…nobody’s ever done it before.
这是个工程上的挑战 这个……还没人做到过
Yes, it doesn’t look like the most advanced technology out there,
虽然这看起来并没有什么高端科技
but you know we’re really pushing the limits of composite structures
但我们真的是在考验复合结构的极限
and you know lightweight design.
类似轻量化设计之类
Ok, so we are gonna do it again?
好吧 我们得再来一遍吗?
A lot of things we are trying now,
我们正在做的很多东西
they start off with some of the capital ideas though
都是从一些好想法开始的
Let’s try to make this super light by doing this.
我们以此将它做到非常轻量
Even when we finish building it, I will skeptical that it’s gonna work.
但就算做出来了 我也不知道它行不行
You know we all love making paper airplanes and really geeky stuff like that
人们都喜欢做纸飞机之类奇形怪状的东西
and this is taking that to that next level.
我们正在将这种精神发扬光大
The helicopter is built of carbon fiber tube,
直升机以碳纤维管为骨架
styrofoam and lots of super glue.
用强力胶粘上聚苯乙烯材料构成
It’s over a hundred feet across
最宽处超过100英尺
but only weighs 80 pounds.
却只重80磅
Unspooling strings make the rotors turn,
不断解绕的线圈带动旋翼旋转
kind of like a giant wind-up toy.
让它有些像个巨大的发条玩具
The pilots all answer to flyer that said simply,
驾驶员们则一遍遍的对飞机说
“Are you light and strong and do you want to break a world record?”.
“你是不是够轻够劲?你想打破世界纪录吗?”
We’ve achieved about three and a half feet off the ground
我们已经达到3英尺半的高度
but haven’t been able to push it any higher,
却没办法更进一步了
so we think that our limiting factor is gonna be trying to achieve the 10 feet.
所以我认为升到10英尺是我们的主要障碍
I think right now, I’m good to go, ready.
我觉得我现在状态很好 准备好了
Broadcast: Altitude record attempts, ready?
广播:挑战新高度 好了吗?
Flight test 11: altitude record.
第11次飞行测试 高度记录
Flight test 11, altitude alteration.
第11次飞行测试 高度改变
Get to go!
准备起飞!
You’re clean, go.
可以起飞 出发!
Oh my god.
哦 天哪!
Holy moly.
天哪!
-Block top. -Back down.
-到顶了 -下降
Bring it down, bring it down.
下来吧 下来吧
Wow!
喔喔!
All clean! Don’t come out there!
其他人闪开!离开那里!
Wow! [Applause]
喔![掌声]
You’re awesome!
太棒了!
This is something that not a lot of people have done before,
我觉得这没几个人做到过
I mean, with the eight-foot flight like
我是说能飞8英尺高这事
I’m the first person who’ve ever flown a human powered helicopter eight feet in the air.
我是第一个将人力直升机飞8英尺高的人
That was the most amazing feeling in the world because,
那是世界上最让人惊喜的感觉
I mean that’s really flying, what do we do, what’s changed,
我是说这是真的在飞行 我们所做的 所改变的
how it is, how we struggling to get at three and a half feet,
我们是如何 如何尽力升到3英尺半
and now we’re popping up to eight feet.
现在却飙升到了8英尺
And you know it doesn’t look like we have to do much more to get higher.
所以我们似乎不用再操心高度的问题了
Broadcast: Ok, this is a record flight attempt.
广播:好的 尝试新的飞行高度记录
For the first time, the Sikorsky Prize’s 10 foot requirement seems within reach.
第一次 西科斯基奖的10英尺要求似乎触手可及
I’ve honestly never gotten to a point where I had to stop because I was tired yet,
说实话 我从未达到过必须停工的疲劳极限
so hopefully that’s gonna be today.
希望今天能够体验一下
There’s still one big problem though.
不过还有一个大问题
There’s no steering on the helicopter and all you can really do is pedal.
直升机上没有舵 你只能控制踏板
The helicopter tends to drift out of its 10 meter box,
直升机很容易漂移超出10米的范围
breaking one of the Sikorsky Prize rules.
这也不符合西科斯基奖的要求
Get up. You’re climbing, good. Keep going up,
正在上升 很好 继续
Push it, push it! Go! Colin! go!
加油 加油科林 加油!
Keep going, keep going, keep pushing it.
继续 继续 继续上升!
Back down, back down, back down, back down.
下降 下降 下降 下降
-Back down, Colin, back down, back down. -We’re out! Clear, clear!
-下降 科林 下降 -出界了!可以降落!
-Are you Ok? -I’m Ok.
-你没事吧? -没事!
A crash has grounded Maryland’s helicopter for now.
因为坠落事故 马里兰小组的直升机暂时停飞了
We’ve had some really major breaks
直升机的损坏有些严重
but we can fix it,
但这是可以修复的
wrap it, rewrap it and reglue it
它需要重新捆扎 胶粘
you konw, give us 10 hours to do anything.
我们需要10个小时来做这些事
The University of Maryland team is already redesigning and rebuilding,
马里兰大学的队伍正在更新设计 重做直升机
trying to control their helicopter’s drift.
试图来限制它的漂移
The Sikorsky Prized hovers just beyond range.
西科斯基奖又飘远了
But the engineers say:
但这些工程师们说:
“It’s not a problem, it’s a challenge.”
“我们追求的不是奖项 而是挑战。”
