Funny thing watching this video...nothing happens!!! Now the same test with a scarebus 340-600, tires exploding...catching fire, too bad the airframe didn't burn. Those french really know how to build stuff
The flaming wheels were a scary sight, but all worked out well. Good to know that this test was done, and done successfully. I just hope that in a real airport, especially a big one, the fire trucks could get to the plane in five minutes.
@xadam2dudex Fun fact, the main reason the brakes burst into flames during a RTO is because it's TOO EXPENSIVE to carry around heavier brakes. Instead they are carefully designed to be able to reject takeoff once, then replace the brakes. WHY would they counteract this saving by adding (UNNEEDED) fire suppression?
@MOBTheNotorious to save the plane and those people in it.. I think they could come up with a weight saving design or just don't carry so much luggage
The test you saw, being able to reject takeoff with worn brakes and sit unassisted for five minutes - THAT is what "saves the people and the plane". If the tire fires became hazardous to the evacuation during that five minute wait, the plane FAILS THE TEST and the design needs to be modified. That's the whole point of the video. Just accept that fire suppression is not there because the plane IS SAFE without it. Most regulated industry in the world here dude.
Your right according to a website dedicated to airliners.The 777-100 was offered to Delta Air Lines and Continental Airlines as an option to replace their ageing L-1011 and DC-10 fleets. Both airlines rejected the offer which led Boeing to make the 767-400ER.
@dmc31400 They keep it usually, for further testing. For example, airbus is using the a340-300 test plane to test the a350 fuselage. But they usually after so many years they will probably donate the prototype to a museum.
Oh, in addition, one of the folks in the cockpit said: "I'll be taking the runway and holding short". How do you do that? You can "hold short" (i.e. up to, but not on the runway)., or you can be on the runway and "In position and holding". I guess I'm just picky.
@mmichaeldonavon now this is a good point... here are boeing test pilots, and they are not using correct phraseology... accidents have happened with less confusing verbage! You can hold short, you can position and hold, or you can clear for takeoff.... you cant do any of those in combination! :)
Just curious. Why conduct the test at 210 mph? V1 (reject) would not be even near that speed. Also, an approach would also not be near that speed. Just don't get it. In addition, as he was braking, I looked for fire vehicles, both sides, who could at least be "standing by", in the event of a catastrophic fire as they were stopping. (like they were going to "lose" the airplane). But the fire vehicles were not positioned for something like that? Hummm, just don't get it.
@mmichaeldonavon 2 things-- 1, this was a test, so they have to "test" to worst case scenario and beyond.... 2, it was a 15k foot runway, and a fully loaded 777 may have a v1/vr speed of around 180 kts (on a 15k foot runway, the 2 speeds would be one because there is enough distance to stop from rotation speed, therefore both speeds would be the same). 180 kts would be around 210 mph. I was not there for the test, so I cannot say for sure!!
@juanchis102 not a simple answer, so sorry in advance. Depends on the weight of the aircraft, the thrust setting, temp, and altitude of airport-- if there is more runway available, and weight allows, we take off "flex thrust"-- reducing the amount of power used from "max t/o" to a flex setting that allows a safe t/o with less wear and tear on engines (lower temps mostly)--- but a fully loaded 777-200 using a normal thrust setting at SL and say 15c to180 kts would be around 45 secs (approx).
@juanchis102 yes, that is the instant the abort is initiated. you can see the ground spoilers come up as well (on auto for t/o, so when power is reduced past a certain point, the aircraft knows the pilot is aborting, and they come up to assist). At that moment, the deceleration is great enough to cause a pitch down moment, just like in a car that is accelerating, then immediately decelerating heavily. And yes, the pilot in this case would push as hard as he could on braking w/ anti-skid on.
The wheels may have been destroyed but if the plane had been full of passengers everybody would have lived and there was no fire or explosions. Impressive.
lol as an airline owner, it might just seem that you would just replace the landing gears and it'll be as good as new (after some inspection of the fuselage and ect)
i would think that its hard to stop and make the engines thrust in reverse in such a short time when just a second ago they were doing full power forward
@dumapies I thought that they could just put the engines in reverse thrust mode at anytime, like in landing the are going 180 mph when then then engage them, so why don't they do it then? It slows it down faster!
Awesome stuff. Take a bow, Everett workers. 9.7million ft-lbs.... god bless the Yanks and their measurement system! This equates to 13 million Joules, or 13MJ.
@FORDGTFANATIC True, that's torque though, divide that by the radius of your truck's tires, multiply by length of runway, then you'll get an accurate comparison of energy to energy, I get very roughly (1 foot diam tires, 1500 ft of runway) 800 thousand foot pounds, that's how much your truck could build up (if it was constantly putting out max torque and had no losses) over the full length of the runway. Powerful vehicle, equals 8% of the brakes of a Boeing 777.
Some tests only allow the use of brakes, simulating multiple systems failures such as dead engines, reverser bucket deployment failure, or hydraulic failures (no flaps/slats or spoilers). Under normal circumstances, spoilers are deployed to help plant the tires to the ground for max braking (by destroying any lifting ability the wing has begun to generate thus far) and reverse thrust is applied as needed.
I believe all planes have the brakes connected to the rudder pedals (I don't fly "big" planes, so I can't honestly say ALL of them do) and let the pilot control left/right braking independantly...although not all planes steer the nose wheel with the rudder pedals (Dassault Falcons for example). Jets of this nature also have an adjustable autobrake system to allow a level of braking force automatically on landing, without any pilot input.
wouldnt it be easier if they would also use spoilers and reverse thrust? they used none of those in this test.. plus, flaps are at 0 degrees, they are normally lowered to 10-20 degrees for take off right? wouldnt that make some difference in this test too?
remeber the prime reason for an abort like this is an engine failing. On a 2 engine aircraft like the 777 its probly not a good idea to use reverse thrust on 1 engine. you probly could do it but it would result in a large yawing.
@simonvega1990 it probably would but at 210 mph with 10-20 degrees the plane would start to hover...i think they did the worst possible scenario, which means more breaking was done to see what the plane is capable of.
stupid isnt ?? however the same people that are bashin these 2 companies have no other choice but fly with them to their destinations .and my opinion is... i love airplanes small or big or boeing or embraer or airbus or mds or w.e i love them all .. not the DASH 9s though i can like those lol.thats my opinion

Rejected take offs do not occur because of wheels catching on fire. They occur for other reasons such as engine failure, tire blow outs, take off warning horns, or other reasons.
Boeing was proving here that their aircraft was safe enough to stop even after reaching maximum speed. Since the force required to do this caused the brakes to heat up to 3000 degrees centigrade, the wheels caught on fire.
This comment has received too many negative votesshow
wat im sayin is all i seen on youtube is a rejected takeoff because of a wheel catching on fire,i know it would happen for other reasons.da only rejected takeoff ive seen on youtube that isnt about the wheels is a fsx video
the brakes apply automatically when autobrakes are set to RTO and the throttles are reduced to Idle or Reverse. The wheels do not catch fire but there is some huge heat development due to the friction within the brakes.
Rejected takeoff in real life are for all kinds of reasons - the wheels catch fire BECAUSE of the rejected takeoff, they are not the cause of it. The rejected takeoff is the plane accelerating to maximum speed and then having to BRAKE down to 0 mph. As you might imagine, this takes a great deal of strain on the brakes and wheels, which is why this is what the focus is on in "rejected takeoff" excercises
Exactly. They have other means to slow down the plane besides just the brakes. But this test shows that with JUST the brakes, the plane was able to stop safely.

P&W engines, weird ha
thegreatdude112 2 years ago
@thegreatdude112 Why is that weird? The 777 uses engines from all three major manufacturers

210 and you would melt the tyres (rated upto 190kts only) Typical speed for max weight take off is approx 150kts. Maybe 160 at most on a hot day!

210 knots is V1 for a 777 at max gross weight? Doesn't same right.

@SuperDrummerGod2112 Boeing likes to overtest there aircraft instead of reaching minimal requirments

@umahuma4 thats boeing for you, if a braking system doesnt stop at max speed it wont at the minimal requirements. XD

210 miles per hour is actually 182 knots.
That does seem right.

@Python1287 mph to knot conversion is 1.15 isnt it
terryk1233 2 years ago
knot to mph is approx 1.15
182 kts * 1.15 = 209.3 mph

Man so much airbus and boeing bashing, people have opinions and my opinion is boeing.

stupid isnt ?? however the same people that are bashin these 2 companies have no other choice but fly with them to their destinations .and my opinion is... i love airplanes small or big or boeing or embraer or airbus or mds or w.e i love them all .. not the DASH 9s though i can like those lol.thats my opinion

Hmmm
sounds like
" dances with wolves."
I was expecting some Indian chiefs to show
up at the end of the runway,,blocking the takeoff...!! LOL !!
but seriously folks,,
it was a lone endangered wolf that caused this aborted takeoff

This is from the PBS documentary. I bought the series - it's in five parts - back in the days of VHS. Still have it. It's pretty interesting to see it all from beginning to end.

Engineering at its best, who ever said the knowledge and excitement of the moon shots was over. We have all become too desensitised to fantastic achievements around us everyday.

I remember watching this series on PBS back in the 90s (I think it may have been NOVA or it was a multipart special). It was really really good!

why do all rejected takeoff gotta be because of a wheel catching on fire?whats wrong with the wheels
gary747pilot 2 years ago
Rejected take offs do not occur because of wheels catching on fire. They occur for other reasons such as engine failure, tire blow outs, take off warning horns, or other reasons.
Boeing was proving here that their aircraft was safe enough to stop even after reaching maximum speed. Since the force required to do this caused the brakes to heat up to 3000 degrees centigrade, the wheels caught on fire.

wat im sayin is all i seen on youtube is a rejected takeoff because of a wheel catching on fire,i know it would happen for other reasons.da only rejected takeoff ive seen on youtube that isnt about the wheels is a fsx video

dont understand this line.
the brakes apply automatically when autobrakes are set to RTO and the throttles are reduced to Idle or Reverse. The wheels do not catch fire but there is some huge heat development due to the friction within the brakes.

Rejected takeoff in real life are for all kinds of reasons - the wheels catch fire BECAUSE of the rejected takeoff, they are not the cause of it. The rejected takeoff is the plane accelerating to maximum speed and then having to BRAKE down to 0 mph. As you might imagine, this takes a great deal of strain on the brakes and wheels, which is why this is what the focus is on in "rejected takeoff" excercises
acnicolet 2 years ago
Exactly. They have other means to slow down the plane besides just the brakes. But this test shows that with JUST the brakes, the plane was able to stop safely.
Simply amazing.

will they use the trust reversals when aborting take off?
