Boeing 777 Rejected Takeoff Test (RTO)

[randytosh]

THAT WAS WAY COOL

[oomblikkies]

Kudos to Boeing

[ktosi11]

FAIL

[blueb0g]

@ktosi11 ... Fail? In what way?

[hpcwsd]

Maybe Boeing should implement a fire dousing apparatus in or near the wheel wells that they can deploy fire retardant?

[perfectionbox]

Impressive. Most impressive (Darth Vader voice)

[Miscskies]

Was there personal on this plane, or was it remotely controlled for the test…?

[GMSamuelRhine]

@Miscskies it just said the pilots were sitting on a ticking timebomb are you fucking idiots retarded or something? if your gonna watch a video than pay attention dumbass

[Miscskies]

@GMSamuelRhine Careful when fiddling with your e-penis that hard, you might jerk off into your underwear.

[MisterChips]

@TheSimonHarris I think you're the dumbass here. Just because I used the word "unique" in my comment doesn't mean i was referring to the uploader - I made my comment in response to the stupid A vs B comments being made.

@RontoTheDog, @stomignigg

The fuses in the tires have a couple of added benefits. As the high pressure nitrogen in the tire is released across the brake pack, it cools rapidly, absorbing excess heat. Because it is an inert gas, it also assists in fire prevention. Firefighters approach from the front or back in case the wheel fails, in which case the pressurized tire causes shrapnel to fly directly outwards.

[RontoTheDog]

I watched the A340 RTO test, and it made me sick to watch... >_>

The tires don't have the fuse plugs that deflate the tires before exploding. When the firefighters went to put out the fire, the ground control argued about it, until they were putting it out while standing next to exploding tires. The ground control ordered an evacuation, and the pilots asked for the ladder, and got absolutely no response. It was disappointing, and completely unorganized.

I am most certainly sticking with Boeing

[stomignigg]

@RontoTheDog: Just to be correct: The "Airbus"-tires do also have these fuse plugs. What you can see on that video are the plugs blowing out. It looks exact the same on the Boinge planes. They just don't show it in this video!

The story with the ladder its an other story ;)

[RontoTheDog]

@stomignigg

Sorry, I must misunderstand you, or something. This video of the Boeing 777 shows the tires slowly deflating because of the melted fuses. On the A340 video, I didn't see any deflating. I just seen every one of the tires explode. I heard that the Airbus tires did not have this valve, which is why they exploded.

[stomignigg]

@RontoTheDog

I'm flying myself airbuses and you can believe me: What you see on the Aribus A340 video are no "explosions". These fuses are there to make shure that the power of the deflated tires goes to the side. Thats why firefighters allways approach straight from the front. Boeing does not show the "fuse-explosion" on the video but you can believe me, it looks quite the same. The tires are not slowly deflating, you see them allready deflated.

[RontoTheDog]

@stomignigg

It seems like the power would be pushed to the side anyway. But anyway, during the A340 test, the ground control even stated that there were "explosions" and you can plainly see massive vibrations in the wings and fuselage, which could cause damage to the struts and possibly the fuselage.

[matatan69]

@stomignigg Agree with you on the fuses, but the RTO test on the A-340 seems to go out of control as the airplane almost catches fire.

[matatan69]

@RontoTheDog , to make the video shorter the blow up scene has been ommitted. but the airbus RTO almost catched fire. On the 777 video, the plane slowly taxies to the fire engines, on the A340 the firemen run to the airplane even though the fuses where still exploding, for me a failed test. but for French authorities a big O.K.

[RontoTheDog]

@matatan69

If this is true, why do they say "Each tire had a fuse plug which melted at a certain temperature, before the tires because so hot they exploded"?

[Mysticlambo]

@RontoTheDog

if the tires exploded they could cause a lot more damage and the whole operation would go to shit, risking the entire airplane.

the tires blow and the airplane falls on nothing but the trucks- which is not good.

[RontoTheDog]

@Mysticlambo This is exactly what I was saying. The others below said that the A380 had a similar fuse plug that would deflate the tired before they exploded, and when I said that the tires DID explode, they said that's how the fuse plugs work. They should not explode. I was comparing the A380 to the B777. The 777 in this video shows the tires slowly deflating to prevent explosion. There was no fire, and it was perfectly fine. The A380 however, did catch fire, and there were many explosions.

[jeetendrag10acc2]

i read that the whole structure of the landing gear can also be damaged if the fuel dump did not evacutae enough mass.

[asulca593]

well worth the expense if you ask me

[TheFirepiper]

It is Edward AFB Runway 04. Brake RTO tests are conducted in stages up to 100% RTO.This test is done on Civillian and military aircraft. The fuse plugs are on each wheel and are designed to go at a set temp. 5 min need to expire prior to the application any water. The test is designed to demonstrate that any resulting fire will not advance up the gear to the wing or underside of the aircraft.

[pilotman088]

what airport is this?

[wanaplayrough]

@pilotman088 Looks like Edwards AFB

[pilotman088]

@wanaplayrough ok thanks

[wanaplayrough]

@pilotman088 I'm 99% sure it is, nowhere has a runway big enough + u could always check the runway number against that of Edwards

[adang118]

This exact thing happened to NZ90 from Narita to Auckland the other day. Aborted take off due to auto thrust fault. All 12 tyres burst!!!

[dergrossen]

@adang118

Yup...they are supposed to burst..like a fuse..filled with nitrogen..no fires!

[mrblujet]

The tires do not burst - they are designed to deflate should the fuse connected between the tires and brakes reach too high a temperature.

[bertie343]

Can someone tell me what this segment is from? What show or special?

[InuyashaKnight]

Look at the video response, i am uploading episodes as we speak.

[boundaryzero]

@bertie343 Its from a "making of" the 777 aircraft, put out by Boeing I believe. It was an hour long and included various aspects of the 777 production including 1st flight, wing destruction tests, assembly, etc.

We had access to it at our Tech school in Vancouver Canada.

[JonteKrok]

Those GE90's had to work pretty hard to get it up to speed ^^

[GeneralKenobiSIYE]

Those were Pratt & Whitney's. Pause it a 2:52. You can clearly see the PW logo on the engine. Being PW, it's no surprise they had to work hard. Would have been no problem for the GE90-115B.

[JonteKrok]

Oh yeah i see it! That's why commented, seems kinda strange it took so long to get it up to speed. The GE90's are truly amazing engines!

[HydroPT619]

1) You ever flown a 777? As a passenger or as the pilot? I doubt so... I never did.

2) Hmm?

3) The market demands so. Passengers want more comfort, safety and faster trips. The companies build new aircraft with those characteristics. It's just like cars... although cars take much less time to build and develop.

4) I don't have that impression. Some of the most amazing aircraft and avition technologies were made in Europe. Airbus, fly-by-wire, BAC Concorde anyone?

[djarmani420]

1) Its huge, and its new technology. I am a pilot myself and fly small aircrafts. Not as easy as the big ones (though more responsibillity) because we fly more manual then the big boys. We look up to them.

2) As a pilot other people often has the image that i'm a rich bastard who likes to party coz we're away with airhostesses all the time. But some people have the image that we are decent and clever people aswel.

3) Safty first, then economy and speed

4) Russians were better...

[ermollejuo]

thank god there is youtube, so airbus can youtube on , "how to make a brake test for you r airplane 101"...I saw the one from the 340 , and here boeing shows its experience...

[jamedorr]

Compare this 777 test to the airbus a340 test where the pilots are freaking out about the stairs... It seems so much more controlled and professional with the Boeing. Or maybe it is just the dramatic background music....

[op3l]

Not only were the wheels destroyed, the brakes were all destroyed too. They were still glowing hot when the water was sprayed.... ouch

[gobuzzrobotics]

whats with the random yellow line goin down the screen

[ddavismedicalart]

This level of quality is what makes America the country it is. The fact that they are willing to spend that amount of money to test brakes sets Americans apart from the rest of the world.

[MisterChips]

This test is a requirement for certification, and is in no way unique to Boeing or the US.

[artgoat]

I saw the same test done on a BMW motorcycle, testing the front brake disks to destruction. There are no requirements for such a severe test for motorcycles.

[TheSimonHarris]

@MisterChips You = Dumb ass, read the comment carefully and you'll see that he is talking about the lack of embedding feature on unique videos (unique = 1 of a kind) So he obviously downloaded it then re-uploaded it

[ttbryson]

uhhh.. they have to do that to get regulatory approval. everyone does. nothing to do with being american.

[judas2969]

boeing the best !! boeing or im not going

[Z06ified]

If it ain't Boeing, I ain't 'goeing!

Good job Boeing engineers - keepin us safe!

[coolbreeze32526]

MAN THOSE ARE SOME EXPENSIVE TIRES!

[curna9]

nice vid!! *****

[eleanorroosevelt1]

we're all gonna die!!!!!!!

[saratcho]

Good study material

[argos408]

amazing video and thx for sharing
