I cant find what does a normal game have to do with this video
Recommended right after airbus announced that they stopped producing A380
Gotta get these last few views in before this video becomes irrelevant.
@@SykeMed this vid literally 13 years old mate
Seems as if UA-cam was listening when you heard that on the news just like me.
This is proof that the 747 is, in fact, the superior aircraft.
@@blockstacker5614 Nop, the economics of aviation are just changing, that's why jumbo jets like the A380 but also the 747 are being pulled out of the major airlines' fleet. The A380 was more efficient, could carry more people and was cheaper to operate that the 747.
will this fit in my honda?
You should buy bigger one because this is little bit small for honda tires....

Energy absorption rate: 5.04 MJ/s
Most things would go on fire having to endure this.
they are on fire though...
+ozzie sheppard No heat needed? This is only true if the airplane is equipped with a kinetic energy recovery system.
+ozzie sheppard Magnetic brakes create exactly as much heat.
+Peter Jerde
But much less sparks and flame.. boring..
+ozzie sheppard It goes to generate heat. A massive amount of heat. Almost exactly the same as using friction except the the system is FAR heavier and the heat is dissipated over a MUCH larger area. Not possible on an aircraft - not even close. You can't 'cancel' energy - you have to move it somewhere.
The brakes knew everything and everyone needed to hide for safety, so it turned into an air raid siren to Alarm people at 0:25
The noise at 0:30 sounds so much like the start of the THX logo sound it's haunting.

What you saw was a worst case scenario, the tire didn't burst, it would have stopped the plane in an emergency. Yes it caught fire but IMHO the test was successful.
they are allowed to in these extreme circumstances(overweigh, overspeed and max throttle of the airplane) but they are not allowed to explode in the first 5 min. and after 5 min the airport fire fighters will have wiped out the fire
Tires bursting when the plane is stopped would not be any dangerous anyway. Everything would drop a bit, but if it burst at speed it could topple the plane.
So yes, very successful.
Johnny Killjoy loool!
The tires have fuse plugs that melt at a lower temp than the main tire material so they deflate slowly rather than bursting.
Tires bursting are very, very dangerous. Not only just from the damage that flying rubber would do, but also since these are probably split rims you could have a couple 50lb hunks of metal flying off it at high speed.
There is a reason when the tires are first installed on the rims they are filled with air while locked inside a cage, to contain the shrapnel.

This was as much energy as an average human would output in about 10 days of normal living/working. All that energy was consumed here in only 28 seconds.
lewis johnson Where have you heard that? That's not true. Professional cyclist can generate around 500W of power for short periods of time with his legs and with this amount of power you could bring one cup of a water to its boiling point in about three minutes.
lewis johnson Hmm, I'm not sure what you are trying to say?
He is talking about the human bodies heat output through metabolic processes alone. You are talking about the total amount of WORK that can be accomplished by a human.
hoghogwild And if this is true, he's still wrong.
Electron Power That may be, but at least we are all on the same page, even if the words on that page are incorrect.
So...did it pass?
+Charlie Foxtrot The 3rd good question....
It's testing an overweight and overspeed landing with no thrust reversers. This is considered an emergency anyway. In this case, the brakes just have to do two things: Stop the plane before the end of the runway, and keep the fire contained long enough for the airport firefighters to respond (5 minutes). They successfully do both.
+Adam Ahmed Yup, its basically a super worst case scenario
Hopefully they had 1.1KM of runway in this fictional situation...
the typical landing field for an airport that supports twin-turbofan aircraft is 1.3km. which shouldnt be a surprise as this would not be an information that the engineers would just skip over in these emergency calculations
WHERE MY PEOPLE GETTING THIS RECOMMENDED 12 YEARS LATER AT??!!!
Present
Yeet
Here
Ayy
Wao
It is an emergency test and this configuration pass it.
Yea brakes are probably destroyed, maybe whole set would nead a replacement, but this acctualy is by the book - after emergency braking whole set should be inspected and replaced in order.
This would be the same if you drove your car with 2 tonnres of payload at 300kph and apply maximum brake - car would stop but brakes and tires probably would be destroyed.
you mean like bmw m5? Im pretty sure brakes last more than one stop from such speed
BMW M5 is a super car and design to stand excesive braking. For this purpose it has a massive tires and a massive brakes. Plane's tires and brakes are acctualy wery tiny commpared to the plane's size and weight since plane can't afford extra weight. So try to commpare this configuration:
small sedan with small brakes with 2 tonnes of payload pushed down the road up to 300kph and then brakes are fully applied. Do you think brakes will be ok after a stop?
b novak m5 more like luxury sport sedan. Ofc it is build for such stuff, since it can actually reach such speeds. Just saying since you hadn't specified what car were we looking at :p
A380 maximum landing weight is 430 tonnes (430,000kg) and landing speed in round 250kph (70mps). So the kinetic energy is 1/2 *m*v2= 1.05 TJ. A380 has 16 multiple wet brakes and 20 wheels. If you can immagine how much energy is 1TJ you'll get the idea.
Actualy stoping a plane is done mostly by revers thrusters and spoilers+flaps, brakes are only partial applied and they are used to stop the plane when speed drops under 70 knots.
b novak yup air resistance is best brake at those speads
This is why they have thrust reverse. And don't try to stop in 1120M :)
and don't fly overloaded.
Good to know you can if needed though. Always good to have durable as fuck equipment for the unexpected.
Thrust reversers don't contribute that much to braking. Same as spoilers. They are only there to disrupt the airflow over the wings and makes the braking force more efficient. Thrust reversers lessen the load on the brakes.
sandynathan
"Thrust reversers lessen the load on the brakes". Yes, and again, that's why they have thrust reverse.
It's not a matter of flying overloaded, most large jets take off at a weight higher than their normal permissable landing weight, it's the nature of having to carry a lot of fuel to get somewhere.
An overweight landing is needed when something goes wrong a short time into the flight and you don't have the luxury of time to spend hours burning or dumping fuel to get down to max landing weight.
This a certification test to ensure the aircraft can safely stop in an emergency situation, this is not a normal landing.
That’s what my step daughter did to my cars brakes. It’s more entertaining when it’s for science.
gonna need some new pads LOL!!!
Do you think they'll have to replace the rotors too?
LOL
yup!!!!
Eric Pettersen I doubt they can even get them off!!! LOL
hahaha pretty sure the entire wheel assembly will be replaced
Now now now what about the tires
Getting recommended after the a380 stops its production

Great job UA-cam 👌
5 MJ/s ! that is pretty crazy. It looks 394000 kg A380 with landing speed of 155 knots (290 km/h = 80 m/s), have total kinetic energy of 2.5 GJ.
So it takes 22 wheels and breaks like in these Break test video (each doing 1/8 GJ), to stop it.
It happens that A380-800 have 22 wheels...
I am a bit concerned now :) Shouldn't it have more? But well, it have 90 m/s here, and it makes a quiet a big difference to 80 m/s. Also 394000 kg is maximal allowed landing weight, most often it would be a bit less than that. (~350000 kg). And often it will land with speed of below 200 km/h. But still.
In this demo I am more amazed by the tire itself, and the rubber, how well it transfer energy to the breaks. Wow.
Hey you need to realize it's not just the disc brakes doing all the work, the air brakes, spoilers and thrust reversers contribute significantly more to stopping the plane than the brakes do.
yifuj
Good point, indeed, I forgot about air drag, and additional air breaks, and possibility of using thrust reversal (are they used in normal conditions, or just in emergrencies?).
Thanks! I will sleep now better, knowing breaks can handled all that easily :)
movax20h Thrust reversers are used in almost every landing involving a turbofan engine. For turboprops or piston driven aircraft, pitch reversers are used.
yifuj The A380 uses turbofans?
Yep, a high bypass one at that, which is essentially 90% propeller plane, and 10% jet. Turbojets are reserved for fighter jets of the past, most modern day fighters use low bypass turbofans, which are more efficient, although they are slower than turbojets. Pulsejets will never be used on commercial aircraft (too noisy and inefficient), ramjets are efficient only at Mach 3 and up, so they have no commercial applications, and scramjets are still under development.
I only just realised, not only is this an overweight test with no other forms of braking, they are also, it looks like, spraying water on the tire - if you look when the tire first makes contact with the dynamometer, the pipe above and between them begins spraying stuff at the tire, so it's also a weather based test
more than likely its to prevent the tire from catching fire.
It's used to keep contact with the dynamometer, basically used to simulate the amount of friction against a runway rather than metal
Probably vht (traction compound)
0:30 where THX got their sound effect.
The only reason why the wheel caught on fire was because that would simulate breaking the plane without reverse thrusting and deploying the air brakes. The purpose of this test is to make sure the plane can properly brake without the two other means of slowing down.
plus it's not even the wheel that's on fire, the disc is so hot its smoking and igniting the o2 in the air, creating flames.
It was to push the limits of the breaks. This was to test how the breaks would react with a overspeed landing no reverse thruster and with a overweight landing as well as simulating a wet surface (Just testing the scenario where everything goes wrong and all the environmental conditions are at its worst). As long as the braking is smooth and the tires don't explode after a certain amount of time it passes.
Techno2301 _ *brakes
Please. "Airbrakes" are called SPOILERS. And what they actually do is to spoil the airflow over the wing and the pressure difference on top and under the wing causing it to lose lift and therefore putting weight in the wheels.
They should also invest in fire push buttons for the landing gear
I know right
yep
+Jia Chun Lim one of the problems is, if they douse water or anything cold onto those burning white hot ceramic/metal brake disks or systems- they will probably explode due to the extreme thermal shock.
+Pasha yikes that just makes ot worse.
Jia Chun Lim Yes, which is why there is a safety mechanism. If it's too hot, it usually means the brake was successful. The whole brake system is usually replaced. At the same time, the safety mechanism is that there is a metallic item, the thermal capacity of which is known to a high degree of accuracy, which is designed to melt and cause a safe and non-explosive depressurization of the tires in case the threshold temperature is reached.
its the THX Sound Effect
i started watching slip and slide videos and now im here...
UA-cam LOGIC
Brain dump: Formula 1 car brakes also reach red hot temperatures but they must not go up in flames. They need to last a number of laps not just one "landing". Sure this was a corner case of overload anyway. 125.2 MJ are 34.78 kWh (in house heating terms that does not seem a lot at first, thinking of 35 x 1kW hairdryers running for one hour .. or in other words this is 29,903.51 kcal or approx. 10 days of food supply at 3000 kcal/day . This equals the energy of 60 bars of 100g chocolate or 120 bars of snickers or 18 slices of Chocolate Tower Truffle Cake from CPK. The wheel withstands approx 30.865 metric tons of weight (so ball park weight of the plane is how much with 22 total wheels => 660 t ? Wiki says A380 weighs up to 650 t. Well that all plays along. Very impressive video !
+Marc Boris Dombrowa ELI5
+Marc Boris Dombrowa Very impressive video. Even more impressive calculations you worked out for us! Nice job.
This isn't a landing, this is an emergency like an aborted takeoff at V1 or V2
Career of brake:
2005 - manufactured
2006 - brake tester (one and done)
2020 - UA-cam star
The brakes did their job. The amazing aspect of it is how the tire doesnt spin over the rim. 500cc two stroke crossbike can break two heavy rim locks in high traction sitiuation, move over the rim and snap the valve. Of course these are tubeless tires and wont fail even if it spins but sure make a mess with melting rubber. There has to be some kind of lock in there or then the tire pressure is just so op it holds it with pure friction.
I feel safer to know that even if the wheels are on fire, they will keep stoping XD
We need fuel prices to go down so the A380 program can continue. Best commercial airlainer to date.
20 years, ZERO crash: go beat that!

One of the earliest videos i watched on youtube
after watching this a few times I'm thinking that the hose spraying the tire is actually spraying sand to increase traction between the tire and dyno, rubber on smooth metal has less tractive force then rubber on high strength concrete.
I might be late on this, but I think that what they were spraying was water. They're basically simulating a landing on a wet runway, which would make sense since they are testing for the worst possible scenario
They are testing the brakes, not the effectiveness of the tire traction on the landing surface. They want ALL of the force to go into the brakes, not to be wasted as tire slippage on the metal dyno surface. There are water tests, but this wasn't a water test.
hoghogwild seems reasonable..
125.2 MJ translates to the energy content of 4 kg of body fat
Or 31,000 kg moving at 90 m/s
while we have to run for hours to lose 4kg of fat, this test uses it in 1 minute

These are carbon-carbon composite brakes. Dunlop was chosen to supply the brakes for one reason above all else: unrivaled expertise. They were the first to succesfully test the technology in aircraft back in 1973, and the first to put them into production to be used on the Concorde.
not pretty, but it still did its job. bravo!
