冷流科技
[Music playing]
大家好 欢迎再次收看ColdFusion视频栏目
Hi, welcome to another ColdFusion video.
一架实用的电动飞机(的原理)还是令人难搞懂的
A practical electric plane is something that has been so elusive,
比一辆电动汽车更难搞懂
even more so than a practical electric car.
在过去的几个月
Over the past few months,
我有机会走近第一架商用电动飞机
I got a chance to spend some time with one of the first commercially available fully electric aircraft
去看个究竟
to really see what the state-of-the-art is like right now.
我将在视频里分享有关这项技术的优势和局限 都是我真实的想法
I’ll be sharing my honest thoughts on the benefits and limitations of this technology later in the video.
Alpha 电动飞机
The Alpha Electro.
将来会怎样呢?
What kind of future are we heading towards?
未来短途飞行电动飞机会不会变得司空见惯
Is it possible that short flights with an electric aircraft will become commonplace?
正如我在介绍优步的视频里所提到的
As highlighted in my uber elevate video,
电池技术最终有所提高
battery technology is finally starting to improve,
正好达到使全电动飞机在某些应用成为可能的水平
and were just touching the state where a fully electric aircraft has just become feasible for some applications,
主要就是飞行训练还有短距离出行
mainly flight training and short distance travel.
成立于1989的Pipistrel Alpha电动公司
The aircraft in question is the Pipistrel Alpha Electro.
正在研制什么什么
Founded in 1989,
是一家斯洛文尼亚的公司 擅长制造轻型飞机
Pipistrel is a company based in Slovenia that specialises in manufacturing light aircraft,
定位为轻型运动飞机
categorized as a light sport aircraft,
包括电池在内它才350公斤
and only weighing 350 kilograms including batteries.
Alpha 电动飞机是第一架用来飞行训练的全电动飞机
The Alpha Electro is the first fully electric aircraft certified for flight training.
飞机造价大约10万美金
The cost of a new aircraft is about 100,000 US dollars.
飞机上有一个20千瓦时的电池
On board, there’s a 20-kilowatt-hour battery,
可飞行一个多小时
which translates to a flight time of over an hour plus reserves.
这可以非常完美用于飞行训练
This makes flight training the perfect application.
电池5分钟充满
If needed, the batteries can be swapped out in 5 minutes.
引擎功率60千瓦
The electric motor that powers the aircraft is 60 kilowatts,
仅重11公斤
and only weighs 11 kilograms.
飞机很轻
Because the plane is so light,
一个人就能轻松推动
it can literally be pushed and dragged around by one person with ease.
我建了一个站点
I founded a site that still takes some getting used in.
不像通常的燃油轻型机
Unlike a regular petrol light aircraft,
那些燃油机用50年前的引擎技术 有上百个零件
which uses 50-year-old engine technology with hundreds of moving parts,
Alpha电动飞机只有一个可动部分
the Alpha Electro has only one moving part,
所以飞机更安全 更容易飞行
and hence the aircraft is safer and much easier to fly.
引擎上只有一个开关 还有一个控制阀
There’s only an on switch and a throttle lever to operate the engine.
通常引擎要做像混合燃料这样复杂得多的操作
Normally, engine operation would be much more complicated with tasks such as mixing fuel on the fly.
提供这种机型的Electro Aero公司位于西澳大利亚的珀斯
The company that got delivery of this aircraft is Electro Aero in Perth, western Australia.
Electro Aero希望飞行训练成本比普通飞机大幅减少
Electro Aero hopes to carry out pilot flight training at a fraction of the cost of regular aircraft.
因为没有燃料开支 保养费用不多
because there’s no fuel costs and far less maintenance costs and the status quo.
目前 每小时的成本在3美金左右
Right now, it cost about $3 per hour to run the aircraft,
也就是燃料引擎飞机的一成
and that’s about a tenth of the cost of a fuel engine.
飞行训练的费用减少了九成
The result cuts the rate of flight training by about $90 per hour
这是Cessna172机型比较的情况
in comparison to a plane like a Cessna 172.
起初的40训练课时
During the first 40 hours of lessons,
飞行员可节约1000美金
an aspiring pilot could save over $1,000.
现在 第一架电动飞机已飞抵南半球
So now, it was time for the first of these aircrafts to arrive in the southern hemisphere.
Alpha 电动飞机从货箱里运过来 之前在斯洛文尼亚制造
The Alpha Electro came in a shipping container from Slovenia where it had been manufactured.
看到飞机的一个个塑料包裹的零部件 还是有点惊讶
An aircraft coming in plastic wrapped pieces was certainly something unusual.
它让我想起我在Twitter和Facebook上面
And it distinctly reminded me of an unboxing,
发过的一个关于拆箱的视频
which I posted on my Twitter and Facebook as such.
我到了飞机的组装地 珀斯南的Jandakot
I was there when the plane was being assembled in an aircraft hangar in Jandakot, south of Perth.
了不起的是 整个的组装过程就花了几个小时而且顺利
Remarkably, the process only took a couple of hours and was pretty painless.
经过简单的飞行测试 就好了
After a quick test flight, it was ready to go.
Electro Aero是世界上第一家取得这种飞机制造资格的公司
Electro Aero are the first company in the world to have this aircraft certified,
比美国和加拿大还要早
even before anyone in the United States and Canada.
这架飞机成为世界上最早的电动飞机
And that makes this aircraft the very first certified electric plane in the world.
我和Electro Aero的CEO Joshua Portlock坐在一起
I sat down with Electro Aero CEO Joshua Portlock,
和他聊聊这架飞机
and had a chat with him about the aircraft.
Alpha 电动飞机就成了第一架电动飞机
So, the Alpha Electro being the first certified electric aircraft in the world,
我们是第一家获得资格的公司
and we were the first to get that certified.
Electro Aero在电动航空训练商业开发方面迎来机遇
Electro Aero now is a great opportunity to commercialize electric aviation in the training sector,
飞行员能够在考取驾照时节约开支 从中受益
where the cost savings are very beneficial to pilots getting their licenses.
长期来看 我们将认证第4 第 5 第6 代飞机
For longer term, we want to certify 4, 5 and 6 seed aircraft,
让空中交通也能利用电力
allowing air taxis to utilize electric proportion.
目前的空中交通主要还是那些设计为长途飞行的燃油飞机
In an air taxis at the moment, they’re using petrol engine aircraft that are designed for longer flights,
在进行10到15分钟的短途飞行
but are only being used for 10 to 15-minute flights.
就意味着引擎比设计的要更频繁地被开启和关闭
That means the engines are being started and stopped much more often than they’re normally designed for.
引擎磨损更多
Therefore, there’s much more wear and tear on the engine,
保养费用有点高 更换频繁
and a lot higher maintenance expense and cycles.
对于电动飞机 你启动和关闭引擎多少次都没关系
In electric, it doesn’t matter how many times you start and stop the motor.
每次没必要要走一个完整的热工循环
It’s not having to go through a major thermal cycle every time,
也没有很多的运动部件
doesn’t have hundreds of moving parts,
只有一个旋转部分 变化方向也没有齿轮箱
which is the one rotating part and direct drive no gearbox.
所以 一小时内的短途飞行很适合电动飞机
So, the short hop flights of sub-one-hour are perfect for electric.
电池也能满足要求
The batteries can already do it,
续电也不像热工循环的引擎那样会受影响
the maintenance is not affected by the thermal cycling like an engine.
看看这飞机
A look around the plane.
前电池空间
So, the front battery compartment,
储有10千瓦时电量
where it stores a 10-kilowatt-hour battery.
前后都有电池
as is battery in the front and in the rear.
两组电池连接起来
So, the two batteries combine.
就能飞行一个小时
I get just over an hour of flight time,
而且还有多余的电储存
and it gives us redundancy.
如果一组电池不能工作
So, if one of the battery’s fails,
另一组电池可以提供大约一半的电量
the other battery can keep flying the aircraft and give you typically half now,
这大约是足够让飞机下降的电量
sort of reserve to bring the aircraft down.
通常 引擎要占据这么大空间
Normally, you’ve got your engine taking up this much space.
对于电动飞机来说 只占用这么一点位置
But instead, the electric motor only takes up this much space.
它很紧实
It’s quite compact.
和蛋糕一样大的马达
It’s a pancake-so-size motor.
充电点非常像特斯拉的
The charge point very similar to the Tesla.
一样安全
Safety.
Alpha 电动飞机安装了弹射式降落伞
The Alpha Electro is fitted with the ballistic parachute
当遇到控制系统失灵或机身故障
that means that in the event of a control system failure or catastrophic airframe failure
你不能迫降 虽然那是安全落地的首选
that you couldn’t glide down, because that’s your first choice of safely bringing the aircraft down.
你可以拉下红色的大手柄
You can pull big red handle,
它会从机身上方发射一枚火箭
and it will launch a rocket out of the roof of the airframe,
弹出降落伞
and pull a parachute out.
它是全机身的降落伞
And it’s an entire airframe parachute.
降落伞下面的绳子会拉紧机身
So, straps that hold the airframe under these covers.
实际上降落伞会带着飞机飘向地面
And it’ll actually be floating down to the ground on that parachute,
安全落地 乘客可以安全出舱
and landing safely so that the occupants can safely get out the aircraft.
看看里面
A quick look inside.
Electro Alpha有EPSI 指电力能源旋转系统
The Electro Alpha has an EPSI, which is an electric power and spin system.
有触摸屏的Garmin GPS
It has a Garmin GPS that’s a capacitive touchscreen.
你能触控放大 就像你的手机一样
So, you’ve got your ability to pinch zoom just like a mobile phone.
它就像一个放在一个便携式装置上的现代的玻璃舱 可从这里解开
So, it’s like a modern-day glass cockpit on a nice portable device second unclip from here.
你可以把它带回家编程或写飞行计划
And you can take it home to programming waypoints or flight plans.
当飞机起飞 任务完成
When the plane was set up and the hard work was out of the way,
该庆祝了
it was time to celebrate.
有几个言论
There were few speeches,
特斯拉参与了进来拍照留念 整体想看看电动飞行器可能的未来
and a Tesla came in for a symbiotic photo opportunity at a glimpse at a possible electric future.
在后来的几天里
Over the next couple of days,
本地媒体看过电动飞机进而试飞
local news teams came to check out the electric aircraft and take a ride in it.
他们对电动飞机有强烈的兴趣 和好奇心
Those keen interest and genuine curiosity.
现在 航空的革命从珀斯起步
Now, to the aviation revolution that’s taken off in Perth,
世界上第一架电动飞机已飞上了天空
the world’s first fully electric aircraft has hit the skies,
所有者相信这是趋势
and its owners believe it’s just a taste of things to come.
这是澳大利亚的第一架这样的飞机
This plane is the first of its kind in Australia.
一家珀斯的公司试制这种革命性的电动飞机 可能会改变我们的出行
A Perth company has launched a revolutionary electric plane that could change the way we fly.
它能成为华盛顿地区飞行的未来方向
It could be the future of flight in W.A.
一个由电提供动力的革命性的飞机将极大的降低运行费用
A revolutionary plane that runs on electricity with the power to slash operating costs and fares.
可能这是你见过的最安静的起飞
Probably the quietest takeoff you’ve ever heard,
成为南半球的首创
and an electric plane the first of its kind in the southern hemisphere.
飞机内部如何?
So, how is it like to fly inside?
如果你飞过轻型机
If you’ve taken a flight inside any light aircraft,
就和那差不多
it’s basically like that,
但视觉更开阔 因为通常窗户更大
but the views are better because the windows are unusually big.
主要你会觉得噪声很低
That aside, the main thing you’ll notice is the noise or lack thereof.
比通常的燃油飞机要安静很多
It’s a lot quieter than the average petrol plane.
噪声主要来源于螺旋桨
Most of the noise is from the propeller itself,
当你飞行时空气掠过机舱
and the air rushing past the cockpit as you’re flying.
我控制需要30秒
I took the controls for about 30 seconds,
对于这样的灵敏度我感到吃惊
and was surprised at how sensitive it was.
食指轻轻一点就能使你处于安全的角度
Just a light press from your index finger could have you banking at a healthy angle.
Electro Aero的飞行员已做了一些试验飞行
Now that some test flying had been done by some of Electro Aero’s pilots,
到了挑战的时刻
it was time for a challenge.
挑战
The challenge.
有个澳大利亚的团队正试图用电动飞机跨国飞行
A team was going to attempt the very first cross-country flight in Australia with an electric aircraft.
团队的飞行员有Rob
The team composed of Rob, the pilot,
还有Richard 金融指导 也是飞行员
Richard, the finance director but also a pilot himself,
还有我 我将会记录那天的情形
and me who would be documenting the day’s events.
计划是Rob由Jandakot机场起飞
The plan was for Rob to fly from Jandakot airport
去一个70公里开外的乡下机场叫戴尔河
to a rural airport called Dale River, which is about 70 kilometres away.
在戴尔河 我们用一个便携式的发电机给它充电
At Dale River, we would then use a portable generator to recharge the plane.
完后 Rob返航
After this, Rob would make the return journey.
那天 我们早上7点在Jandakot碰面
So when the day came, we all met at Jandakot hangar at 7 a.m.
我们检查了充电器 装上了车
We performed some checks on the charger, and loaded it onto a truck,
调阅了天气 看是否适合飞行
and check the weather to see if it was suitable for flying.
Rob起飞 Richard和我驱车前往戴尔河机场
From there Rob took off, while Richard and I drove to Dale River airport.
当我到了那里
When I arrived at Dale River airport,
我想那里更像是一块高速路旁的废弃的农地 而不是一个机场
I thought it looked more like a patch of abandoned farmland near a highway than an airport.
无论如何 Richard和我得等Rob的到来
Regardless, Richard and I would wait for Rob’s arrival.
安全起见 团队决定
For safety, the team devised the decision point.
当电量65%时 执行决定
That the decision point comes into play when the batteries at 65%.
假如Rob在这时没有飞完半程
If Rob hasn’t flown half the distance at this point,
他最好返航 落地
then it would be best for him to turn back and land.
主要原则是不要去挑战那仅剩30%电量
The main concept is he never went to break through that 30% reserve battery.
加上在Jandakot与DaleRiver之间没地方落地
There would be nowhere to land in between Jandakot and Dale River,
这才是关键
so this was important.
在地面 我们用苹果手机应用跟踪Rob的实时飞行
On the ground, we could track Rob’s flying in real time with an iPhone app,
很酷的
which I thought was pretty cool.
过了一会儿 我们看到了
After a while, we had a visual.
他很快落了下来
And he touched down shortly afterwards.
我问Rob关于这次飞行
I asked Rob about the flight.
他其实很担心
And he said that he was worried,
因为很强的逆风 飞机爬升非常快
because the plane was climbing too fast due to an unusually strong headwind.
在这种情况下电量下降很快
This was a concern as the battery tended to drop quickly under these conditions,
额外的电量用光
because of the extra power used.
这种情况下 计划用便携式发电机给飞机充电
So at this stage, the plan was to recharge the plane using the portable generator.
不幸的是 不知道什么原因
Unfortunately, for an unknown reason,
发动机不能全电流充电
the generator couldn’t handle charging at the full current,
一试就熄火
and shut down immediately when it was tried.
太搞笑了 因为它应该可以的
It was funny, because it was supposed to take this rating.
当电量只剩一半时 发电机会工作一段时间然后瘫痪
When at half power, the generator would work for a while before conking out.
它需要降温半个小时 才能再试
It needed to cool down for about half an hour before he could try again.
顶着大太阳 经过几个小时的折腾
After a few hours of frustration in the hot sun,
我们充足了电 安全返航Jandakot
we finally got enough energy into the batteries to make a safe flight back to Jandakot.
这就是澳大利亚的第一次电动飞机跨国往返飞行
And this completed the first cross-country return flight in Australia with an electric aircraft.
说实话
And for the truth being told,
这种情形很生动的反映了电动飞机目前的局限性
this situation vividly highlights the limitations of electric aircraft at the present moment.
跨国飞行将来一定很普遍
For cross-country flies to be more practical in the future,
你一定不希望再依靠老式的发电机
you wouldn’t want to depend on an old generator,
你可能需要超级充电器 3相动力电系统
and you would need a supercharger 3-phase power system readily available,
问题还在 但电池的能量密度在提高
until this infrastructure is in place and battery energy density improves.
目前 飞行训练是电动飞机的最佳应用
For now, it’s only really flight training that is the optimum use case for electric planes.
我看长距离飞行得等2到5年后
I see longer flight applications being about 2 to 5 years away.
总的来说 目前的处境很有意思
So all in all, it’s an interesting state that we are at right now.
我们站在新的起点
We’re definitely at the beginning of something new.
无聊如何 还是要做的
Anyways, that’s going to do it for this video.
我想问 如果有人住在珀斯
And I do have a special treat for you if any if you happen to live in Perth,
你是否愿意去看 甚至自己还飞一趟
or do you want to see the Alpha Electro in person and fly it.
我和Electro Aero 合作拍了这些视频
I’ve teamed up with Electro Aero for this video.
假如你用ColdFusion的折扣码 你的首次飞行减50美金
If you used the discount code ColdFusion, you can get $50 off your first flight.
我将在下面留下链接
And I’ll leave the appropriate links below.
强调一下 Electro Aero正在做一些非常酷的事
As a side point, Electro Aero is actually doing some other pretty cool things.
其中之一是电力推动系统的专利设计
One of them is a patented design for electric propulsion systems,
这给公司赢得了几个大合同
which’s won the companies some big contracts.
