Pratica di Shadowing: Dominator 3 Tornado Tank ULTIMATE Tour - Impara a parlare inglese con i video
Creazione lezione...
1
The inside of a tornado.
2
Only five research papers in history have data from in here.
3
And that's why we built this monster.
4
And everything about this vehicle is custom built.
5
The way that it looks, the way it operates, the instruments on it, everything is custom built by us.
6
Five, four, three.
7
This is real life Twister.
8
This is the most capable storm chasing vehicle on the planet.
9
This is the Dominator 3.
10
And as you can see, there's plenty of space for sponsors.
11
To study the inside of tornadoes, you can't set up a lab and expect one to come through.
12
So the best way is to build a lab on wheels and park the gear in the path.
13
But if the powerful winds get underneath a vehicle, this can happen.
14
A flip.
15
So that's why we've got this skirt on the bottom here.
16
This skirting has been added across the entire base of the outer armor, and that prevents wind from getting underneath the vehicle.
17
But right here you can see that there's some space where the wind can get underneath.
18
This is the height that we drive down the highway, but we get in the path of a tornado.
19
We have a system that lowers the vehicle and drives spikes into the ground, and we're going to show you that outside in a second.
20
It's this method, and the rocket system will also show you, that have the highest success rate.
21
So up here, check this out.
22
This is victim of the real problem of a tornado.
23
Hold on!
24
Hold on, Nate!
25
Flying debris.
26
This is heavy-duty plastic, and this was shattered and snapped off by a juniper tree inside that last tornado intercepted.
27
So that leads us to the armor system on the Dominator 3.
28
This is three-quarter inch steel, and this is what the shell of the Dominator 3 is made of, and we've covered that with this rough surface right here.
29
This is a Kevlar-based polyethylene, basically a bulletproof vest for the Dominator 3, and anything just bounces right off.
30
Okay, and over here protecting the lights is a quarter inch polycarbonate plastic that's also bulletproof.
31
And the Dominator 3 has a double window system.
32
We have an inner and an outer one for dual protection from flying debris.
33
So this is a polycarbonate windshield and look closely and you can see all these little dents.
34
Those are from pebbles moving at speeds of over 150 miles an hour inside of the tornado.
35
Now I'm going to show you how tough this stuff is.
36
That's tough.
37
Dominator tough.
38
Tornadoes do some weird things.
39
And recording these events helps to verify and guide other researchers' computer models.
40
And that's why we want to maximize our chances of getting great footage.
41
So that's why we've redesigned the entire back end of Dominator 3
42
and coated every square inch of it with polycarbonate plastic so that you can see up at the tornado,
43
you can see all angles of the tornado in progress and capture that very valuable high resolution footage.
44
We can also pop the back open
45
and there's plenty of room for our scientific gear including our rockets which I'm going to show you shortly.
46
Also plenty of room for adult diapers,
47
underwear, but under here these are the muscle and cardio systems of the Dominator 3.
48
When we talk about raising and lowering the vehicle this is what makes that happen.
49
Listen to them purr.
50
And if you go from the air compressors and follow these lines up here, they go up to our door system.
51
But these doors weigh 800 pounds with all the armor so
52
if you look up here we've got this complex valve system to support
53
that weight and to help you push them open from the inside yeah that's our lift system
54
that helps lift the heavy weight of the door.
55
And these gall wing doors aren't just for looks.
56
So when we're close to a tornado, we need to look at the sky.
57
But also when you're up close to a tornado, you're very near the hail core
58
and you could easily get a softball sized hailstone coming through the sky and hitting you in the head.
59
So these doors raise up and they give us added protection from overhead.
60
While the door is open, you can see the original truck door here
61
and then you can see all the armor we've added on on the outside, very thick.
62
Another advantage of the gull wing door system on the Dominator 3 is it fixes a big problem
63
that we found out with the Dominator 1 and 2.
64
So imagine you're out chasing a storm with Team Dominator
65
and you're out looking at a tornado and you have to hop in the Dominator fast.
66
All right, we gotta go guys, we gotta go.
67
Oh no, look at that, we can't go.
68
You actually can't shut the front door until the back one is closed.
69
It's because of how all the heavy armor fixed together.
70
So the people in the back might be out panicking, Maybe they're going to the bathroom, but this is a big problem right here.
71
But now it's fixed on Dominator 3 with the Gullwing lift system.
72
Pinch it off, we gotta go!
73
And the last thing before we jump in is I'm gonna show you the engine underneath all this.
74
Squeak, squeak, goes the Dominator 3.
75
So the whole reinforced hood of the Dominator 3 comes forward like this, giving us a look at the powerful engine inside.
76
This is a 6.7 liter turbo diesel engine, And this is what drives the 10,000 pound Dominator 3 at highway speeds of over 70 miles an hour.
77
And we can also accelerate very fast.
78
If we have to run from a tornado that's too powerful to intercept, this power stroke engine gives us the pick-me-up to get out of a hard spot.
79
And believe it or not, this thing gets about 16 to 17 miles per gallon on highway speeds.
80
And in case we need a pit stop, we get a flat tire, we have these protective flaps that we can lift up and access the wheel.
81
Heavy duty tires, of course.
82
All right, let's step inside the Dominator 3 and show you how we get our data.
83
Yep, eye contact, yep, okay, yep.
84
Three, two, one, release.
85
Well, welcome inside the cockpit of Dominator 3.
86
Good to have you.
87
Kind of a standard F-350 look from the inside.
88
See some cup holders, you can put your Mountain Dew energy drink right in here
89
but you can definitely see a couple things are added we've
90
got this peak of the armor the peak of the armor
91
on the hood is designed to funnel the wind up
92
and over the top of the vehicle so
93
that you don't get all this debris just slamming into the windshield
94
and this is where we're putting our updated live streaming panel
95
because yes we stream live our tornado intercepts and storm chases as it happens
96
looking in the back you can see
97
that we removed the bent seats of the ford f-350 and replaced it with three additional captain's chairs.
98
We pretty much live inside this vehicle.
99
Comfort is important as well.
100
You got a great storm chase?
101
So our research is divided into two modes, intercepts and rocket deployments.
102
Intercepts are measurements at the ground level of a tornado with the dominator.
103
We actually started with super heavy ground probes that we would drop in the path of a tornado.
104
But after having some tornadoes bend away and miss, we decided to turn the whole vehicle into one big probe.
105
That way we can adjust forward and backwards with the tornado right up until the last second.
106
So when we get in the path of the tornado and it's bearing down on us, I press number one to drop the vehicle flush to the ground.
107
Bingo bingo bongo.
108
So now we're flush to the ground but we want to make sure we're not thrown.
109
So we hit this second switch.
110
The spikes go into the ground about six or eight inches and that anchors us to the ground when the tornado arrives.
111
Then we go to the outer switch.
112
So we're lowered to the ground, the spikes are at, the windows are up, now we're in full-blown intercept mode.
113
Intercepting a tornado is one of the most intense experiences of your life.
114
The winds feel really powerful, so powerful that even dominator is bouncing up
115
and down they make this really low roar almost like a freight train
116
or a really loud waterfall like niagara falls uh the dramatic
117
pressure fall makes it feel like a lot of weight is
118
on the shoulders your eardrums are about to burst out
119
and it happens really fast suddenly the sun is coming out
120
you see the blue sky you see the tornado moving off in the distance
121
and you realize that you survived it
122
and then suddenly you're overwhelmed with happiness you realize
123
that the dominator 3 got its job done and most importantly we know
124
that we collected some incredible data from inside of the tornado.
125
But as rare and valuable as that data is, it's from the ground level, just like those four other research papers.
126
The Holy Grail now is actually getting data above ground level, in the heart of the tornado.
127
It's only been done once, and that's where our rocket research comes in.
128
Team Dominator has spent over 10 years funding different methods trying to get probes inside, but we kept running into one problem.
129
A wall of powerful sinking air surrounding the tornadoes.
130
It would knock our probes out of the sky right before getting inside.
131
But in 2019, we finally settled on a method that would punch through the sinking air.
132
And here is the Team Dominator rocket.
133
Our rocket has two main parts, the rocket itself and this right here.
134
This is the Team Dominator Skyfall sensor, custom made by our science lead, Mark Simpson.
135
We're going to fit this sensor inside the nose cone.
136
We're going to attach a parachute on it, and we're going to get ready for launch.
137
We also have a parachute inside of the rocket.
138
It's all ready to go.
139
So we've got the sensor in the nose cone.
140
We're going to stuff the nose cone on, and now we're ready for launch.
141
To launch a rocket, we need to get in the perfect place in the storm, right in the inflow notch of the supercell.
142
That's where all the wind is flowing in toward the tornado.
143
and we need to be at least a quarter mile away from the vortex.
144
There we go.
145
Rockets attached.
146
So this stop right here is what keeps the rocket in place.
147
We've got the blast plate.
148
That's needed, too, to give the propulsion necessary to launch.
149
And we have these long rods, too, because that stabilizes the flight path early on.
150
And we have the two rocket engines.
151
Now I'm just positioning it to connect the igniters to the engine.
152
That's what provides just a little bit of fire in there to ignite the rocket engine.
153
I'm going to make sure positives on one side and negatives on the other and they don't touch.
154
This is very intense when you know you have an F4 tornado bearing down on you.
155
It's going to stay just to our west.
156
What's marked?
157
Am I connected?
158
We now have continuity.
159
I know that the red and the black are connected properly because the continuity lights are on.
160
Can you close your hands?
161
You gotta stand up and reach out.
162
All right, we are launching in 10, 9, 8, 7, 6, 5, 4, 3.
163
Okay, so now the rocket is flying toward the tornado.
164
It punches through the pocket of sinking air around the vortex.
165
And once inside, the nose cone pops off and the parachute deploys, and it's carried around inside the vortex, just like the movie Twister.
166
And we've got to get after the rocket.
167
So as the probe is getting carried around inside of the tornado, we're immediately getting live data like this.
168
We've got pressure, relative humidity, we've got IMU acceleration, we've got our GPS position.
169
And we even have the data of exactly how the sensor is tumbling around in 3D.
170
But right now we're only getting live data at one time per second.
171
But we actually have to recover the physical sensor to get the super high resolution data.
172
But for the Lawrence to Linville, yeah, four tornado.
173
The tornado carried it over 26 miles away from where we launched it.
174
Mark, is the rocket in the tornado right now?
175
I believe so.
176
How high is it?
177
10,000.
178
10,000?
179
10,000 feet?
180
No, 10,000 meters.
181
Yeah.
182
30,000 feet, guys.
183
And there it is, the yellow.
184
There it is right there, the nose cone.
185
Made it that bright yellow color so you could see it easily.
186
See the nose cone and the parachute?
187
and that is holding the sensor with the valuable data inside. So here it is.
188
The moment of glory here when you retrieve the nose cone.
189
This contains the high resolution data from inside the tornado, the pressure fall, the wind speed, all that 3D information inside,
190
and it's all contained on the sensor in the nose cone.
191
So we're going to head back to the Team Dominator headquarters and show you the data right now.
192
So here's the actual data, the GPS positions of the rocket launch that we had into the Linwood EF4 tornado.
193
These are the first ever data points measured above ground inside of a tornado core flow in history.
194
And so each of these are data points measured at a rate of five times a second.
195
The red is the actual rocket.
196
And so it was going toward the tornado.
197
And then the parachute popped off with the nose cone and the miniaturized sensor.
198
And then it got entrained into the tornado.
199
So if we look from the top, you can see that it did nearly two revolutions around the inside of the tornado.
200
And at the same time, it was measuring a pressure fall of over 100 millibars.
201
That's how you know it was inside the core flow of the tornado.
202
And this probe then rode the mesocyclone up to 30,000 feet before falling to the ground near Leavenworth, Kansas, over 26 miles from the launch site.
203
And we wouldn't have found the probe if we didn't post a picture of it.
204
That's how we found the probe, over 26 miles away from the launch point.
205
And thank you to Matthew and Jeremy for keeping their eyes open
206
and finding that sensor in the lawn of a church in Leavenworth, Kansas.
207
We're going to be doing another video
208
and take a deeper dive into this first ever data collected above ground inside of a tornado.
209
We're also going to talk about our future research plans, launching dozens of rockets into the tornado at the same time, dozens of sensors.
210
That way we can measure gradients in pressure, gradients in temperature, and really get a three-dimensional understanding of the tornado.
211
Storm season is about to get started in a big way.
212
We're going to have several months of severe weather and storm chasing.
213
So be sure to tune in to Team Dominator Live.

Cos'è la tecnica dello Shadowing?
Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
