Volcanic Ash and Jet Engines - Sixty Symbols

[iLOVENATURE2011]

an analogical video...truly amazing...

[muhammadzahmad]

wise engineers should have solutions to this....

[dreasim]

darn those leather chairs....

[spankthereasoner]

I heard the same noise at 2:26, it doesn't seem like a fart. And either way, it doesn't matter.

[dilibau]

OMG 04:56 !! daaaaang!

[counterclockwise123]

In the video he only seems to reference the two incidents of when planes actually flew through ash when describing what happens to the engines. Why haven't they actually gathered some of this ash and deliberately sprayed it into an engine in order to test and study what happens.

[GeneralBolas]

@counterclockwise123 Who says they haven't?

The problem isn't that they don't understand it. They understand exactly what the effects of flying through volcanic ash will be. The problem is that you can't really design a jet engine to handle it without substantially sacrificing power-to-weight ratios, if it can handle it at all. There are simply some things that are not feasible engineering wise.

[soberek]

Anyone noticed he looks and sounds just like Neil Armstrong? Same looks, Hair, voice. Cool.

[ericsbuds]

great story, subscribed!

[DeltaPhi79]

Avoiding it would be a good idea but another simple one that's actually not simple: MAKE A GIANT DUST FILTER! XD

[GeneralBolas]

@DeltaPhi79 In general, if you're talking about a matter of engineering, and you think you have thought up a simple solution that thousands of very smart engineers haven't used, you're wrong.

Exactly why, I can't say for certain, but I imagine a "giant dust filter" would also slow down the velocity of air flowing through, thus making the engine not work. Also, what do you expect to happen when that filter gets clogged with dust, as would quickly happen when dealing with volcanic ash?

[MintBIRDIE69]

FART!!!!!!!!!!!!!!!

[MintBIRDIE69]

uhh

one question

WHY ARE YOU SMILING??

[Lessinath]

There's no solution right now to this, at least that uses technology that actually exists... So, if you want to help, invent a colder engine with the same or greater power-to-weight ratio (and make it cheap enough to be practical), which would solve this problem.

[ggmaki85]

But what's the solution? If the next erruption sends ash into the air for 4 month we are in big trouble...

I they should work really hard on a new engine, or some filters... Maybe something to cool down the vulcan, or stop the ash spreding so easily

[chrisdkdk]

With all the lightning and shit it's like hell on earth!

[xDILS]

Lol

[pauljacksonmusic]

Interesting

[The8thDOCTOR]

Ryan Air will NOT stand by EU regulations and pay for hotel & board for TRAPPED passengers

[trombone7]

How did the engines restart ? In both cases...

[mackat4ck]

@trombone7 The glass coating on the turbines broke off when they reached colder air, thus freeing the combustion chamber enough to restart the engine.

[trombone7]

How did the engines restart ? In both cases...

[wandereruk44]

So what? The bottom line is that the BA and the KLM flight flew right into the ash cloud and understandably suffered damage. The ash cloud over Europe was much more diffuse and gave no reason to suspend flights.

[lopzilla]

@wandereruk44 - another ( consultant ) happy to gamble with the lives of passengers.

Throw a handful of sharp dust in the air and take a very deep breath, I wonder if you'll cough !

[wandereruk44]

@lopzilla No but trained as a chemist and trained to think and analyse rigourously. All I was saying was by the time the ash cloud reached Europe it was far more diffuse than in the BA and KLM incidents. And what do we find now? The ash levels were 20 times lower than that deemed unsafe to fly in.

[ksandom40]

An excellent explaination!

[1971ELLIOTT]

Iceland's banks refused to give our money back, I know the clouds are an act of god, but I think the UK should sue Iceland and claim compensation and get our money back that way.

[robertwc82]

is that what happens if you put sugar in the petrol tank of a car too?

[RollingStone000]

@robertwc82 maybe in a new car, but not in anything '05 or older. I recall seeing a Mythbusters episode where they did that and the car was still running.

[robertwc82]

@RollingStone000 huh, really? thats interesting. but my question was is that the effect its supposed to have (ugar in a tank) to block of the air intake, or does it cause damage elsewhere (you know, if it was to effect it at all)

[RollingStone000]

@robertwc82 I'm not a mechanic mind you, but I think it screwed with the combustion of the fuel and not necessarily the air coming into the engine.

[robertwc82]

@RollingStone000 seems logical

[Dahl4life]

They covered this in an episode Aircraft Investigation when a plane shutdown after fying through ash. All engines failed, however, the pilots managed to descend and restart the engines. When they flew through it everything lit up and flames were shooting from the black of the engines just like this guy mentions in the video. I don't think a plane has ever crashed because of this problem, but it's the risk of not being able to restart the engines once they fail.

[SuperGuyverman]

Unbeleavable

[SK8ersFATE]

1:34 HE SAYS HUGE BUT SEZ IT WEIRDD

[dem1275]

Very informative video and excellent information. The wee fart made it funny too.

[watfordtripod]

I know a fart when i hear one..My god,i think he unloaded a monster.

Sounds like a Beer fart more than a curry fart.

[BartOrzel1978]

2:17 definetely fart :-))

[gapamu66]

ah ha ha ha ha classic , he farted

[shamelads1289]

FART

[funktwin]

Finally. Proper information.

[WestGreenNutJob]

First the Icelandic banks go skint then the country catches fire........ sounds like an insurance scam :)

[SpacedTime]

I heard the volcano lasted 2 years the last time it erupted. What if that happens again? No jet engines for that long over Europe?

[donkeywarmer]

Better out than in, atleast he didn't follow through. lol

[iTzBatesy]

turtle head at 4:56

[iTzBatesy]

4:56 .. He has a turtle head?

[NintendoStar01]

lmao he farted

[Lizzzie1963]

FART! dirty old man! haha

[chunkyfecalbreakfast]

Great stuff, good to see someone finally explain it in layman's terms but with enough detail to still be interesting.

[StewartBrasil]

2012 is near.

[007shakers]

pause it at every 2 second and you have an epic face

[montyj2y]

fart attack

[TomSkaax]

FUCKING ICELANDICS

[Darksonicfan841]

loads of teachers at my school wernt there because ofthe airport closures some ofthem i am glad they are there

[absalutebeginner]

blocks the air passages lol

the right amount of air definately came out of his engine

he knows his hit though fair play

[kingster991]

2:17 was dat a fart??? hahaha

[DerbyBrandon96]

awesome fart well struck did it smell of eggs lolzzzzz

[frozenmouse76]

his hands on demonstration of expanding gasses at 2:17 is very interesting.

[85sprawson]

interesting. but he defo farted lol

[StaithUK]

Jeez, this guy talks any slower and youtube will have to implement a x2 fast forward feature.

[adyb543]

w w w . i g o t 4 f r e e . c o m for free stuff

[DJLaterall]

lol did he just fart at 2:17? thumbs up if u agree!!! lol hes been eatin beans man!!!

[mraaronyuppy]

@DJLaterall LOL yeah i heard it

XD

[SPQRRoman]

he farted lol

[JonThm]

So not fatal! The present fuss is to do with Euro tunnel

[Nicka712]

have a patience

[migfoxbat]

DOD said today that it caused damage in their own test flight,and then today also BA say their test flight had no problem So the ban is lifted just like that Putting money before human life

[xxxAlicerocks27xxx]

Well Basically, all we need to get rid of the ash is a Big gust of wind to send it upwards, so the sky Can be clear so the Poilets can get to there Destination! and people can get back to where there where!.

[DGTLINSaNITY1]

I thought if the engine failed when it is diving down towards the ground, the ash gets pushed out by the force of the air allowing the engines to restart????

[AK04KGJ]

Can we not just get Mr. Dyson to invent a really big vacuum cleaner!!

[AK04KGJ]

This stupid volcano has stopped my door handles coming from Germany, not impressed!

[labrax100]

why dont the flying machine fly under the cloud at 34 feet

[Pierce1978]

now we know why Frodo and Sam had to walk to Mt Doom instead of taking a plane!

[DGTLINSaNITY1]

@Pierce1978 Lol

[bernardm636]

I'm No Expert But BLA BLA BLA BLA BLA, So On And So Forth, .....=)

[makichut2]

u scared me

[thetimster99]

very interesting, but sorry was it a fart at 2:17? lol

[EquuleusPictor]

@thetimster99

Yes mate it was a fart, but it was meant as an illustration of how the combustion chamber works

[IIxXHAMXxII]

@thetimster99 ye i think it was well funny

[McGrot]

@thetimster99 LOL!!

[unastellarkavanagh]

@thetimster99 It sounds really like one :P Although it's probably just a leather type chair squeaking!

[damianpaz]

@thetimster99 It was a sort of a liquid spacing over the turbines blocking the air passages.

[thetimster99]

@damianpaz yes thats what i thought, honestly!

[energy27uk]

The airlines are complaining like mad at the moment because of the money they are losing. I know these companies need to operate their planes to stay in business but it only needs one of them to come down as a result of flying into thicker ash cloud and it will be the families left behind that suffer most. They need to send the stranded home via ships or trains and keep non emergency flights on the ground.

[DazzleStar94]

@energy27uk But the thing is, they would lose even more money replacing a plane, which would cost millions to buy. And the compensation paid to families. It's natural, and there's nothing that can be done about it!

[xxxAlicerocks27xxx]

@DazzleStar94 I Agree, by a mile! All the need is a big gust of wind to clear the Area!

[vShadowWARRIORv]

Thats why mums go to iceland :)

[EMOSLVTUBE]

@vShadowWARRIORv lmfao that was legend !!!

[brummiepride]

That volcano has done more to stop immigration in the last 2 days than the government has done in the last 20 years :)

[labrax100]

@brummiepride well said

[FatsNice84]

anyone else hear him fart at 2:17

[1123anon]

@FatsNice84 hahahahaHAHA lol

[YoungThomsen]

@FatsNice84 hahahahaaaaa

[sixtysymbols]

@FatsNice84 I can assure all it was a squeaky chair in the conference room... And glad everyone has sight of the big issues! :)

[Rrob2593]

@sixtysymbols lies

[tumadoireacht]

@sixtysymbols it sounded more like a a hot gas compressor than a chair to me ! great to see an intelligent(if flatulent!) man contextualize this -some photos of glass encrusted fins would have been good

"all you can do to keep out of the gas cloud is cut down on the broccolli and onion omelettes"

[OHT53]

@sixtysymbols One bad apple doesn't spoil the whole barrel. A reference to "everyone".

[MiraSekelsky]

@FatsNice84 it's all the funnier because he's talking about 'hot, compressed air'...!

[MrAliyak]

@FatsNice84 LOL. I think he tried to let a sneaky one out!

[pompom758]

Whats the difference between Cheryl Cole and The volcano ? The volcano is still blowing Ash :P

[darrencol]

"That's the compressor which compresses it." lmao

[JackWoodmansey]

The end of the flame war...

[TheJakeRusby]

whos laughing at peter griffin's volcano insurance now ?

[smellyboyband]

@TheJakeRusby no1!!!!:DXD

[dan19evans]

@TheJakeRusby haha lmfao thats the funniest thing ive heard all day !

[360kal]

if any one is looking for a video of the incident the guy was talking about type -  air crash investigation: all engines failled part1

its very interesting

[Cobonline]

its not only in the UK

[SpazzyNoodle]

Hmm... It's funny how on the news that the airlines that are losing money are sending up test flights and saying the planes are perfectly fine are juxtaposed by the Met-office, who are not losing money, are sending planes up and they came back with engine damage.

I wonder who is telling the truth?

[dalesteel]

@SpazzyNoodle fail. thats not true.

[oneratcardiff]

@dalesteel

it acctually is.

My father told me about this story.

apparantly one flight plummeted so fast, that passengers not wearing seat belts hit the over-head luggage compartments.?

lol..

[dalesteel]

@oneratcardiff lol. the dust does fuck the engines up, and it might be unlikely to bring a plane down, but they cant risk it. The planes cost too much hahahah LMFAO.

[toweronepower]

@dalesteel Its lives they are worried about not cost of crashed planes.

[dalesteel]

@toweronepower jesus it was a joke. did you not understand that by the fact i said 'LMFAO' after? my god get a sence of humour.

[zen66608]

Now now Iceland, if you can't control your volcano, you shan't be allowed to keep one. >:V

[serpentide666]

this year i'm going to vote for the 'Icelandic volcano party"...they have done more for immigration in 5 days than the british government has down in 10 years!!!!....can i get a HELL YEEAAHH!????

[31EsoxLucius]

@serpentide666 I'm with you....

[liverpool1sgreat]

the ash solidifies and eventually fall off

[DirrtyKarma]

thet's the compressor, which compresses it...hehe made me giggle a bit.

[Thereganification]

gas turbine engines will make the ash form into a crystal style glass form that will cause the engines to fail and flameout and as the aircraft decreases in altitude the force of the air rushing through the engine will force the "glass" to slowly break up and will allow the engine to start up again but with quite a large amount of damage to the engine.engines will only start if the entire engine is running to a certain speed to much or to little will not allow the engines to re ignite

[andyjy2015]

@Thereganification

it's the safest sign nature has ever shown of a culmative script

[andyjy2015]

@andyjy2015

experiance life is moved forward by experience

[andyjy2015]

@andyjy2015

symbols = signs lol

[andyjy2015]

@andyjy2015

60 = dreams

[andyjy2015]

@Thereganification

@andyjy2015

60 symbols........ SS..... lol peace :) RAF peace :)

[LogInForPaper]

Who shall we sacrifice to appease the volcano?

[Tgodlonton123]

my mums stuck in france because of this, hopefully the wind direction changes so it will fuck off to america! lol

[lunnyyy]

god i cnt take the spitty noises coming from that mans mouth its disgusting

[MarkMcC90210]

@lunnyyy fuck you, you ignorant bastard

[lunnyyy]

@MarkMcC90210 fuck you cunt

[raal2k8]

hey its me lol volcanic ASH lmao

[iMakeVideoz4You]

fk it!! :[ my holiday is gonna be on soon!! on may :/ i hope that ash will go

[Tommiclio]

@iMakeVideoz4You Same here!

Im off to Vegas i hope!

[Rmister1]

are all the airports in europe closed or is it just the uk

[katiexhxoxoxo]

omg that was scary 2 watch : (

[MaxHez]

I'm stuck in france!! :D

[GWIvid]

@MaxHez lol cool. wats it like?

[Loubatron]

so all planes are strictly not allowed to fly.. that is of course the ones taking overhead pictures of the volcano right next to it obviously

[buggardup]

Well said , and i think walsh of british airways needs a boot in the balls for suggesting its safe, considering it was a BA flight this happend to . One thing thats clear BA have no problem of sacraficing passenger safety for profit . and its a well known fact that profit far outways safety in the airline business

[AgentEnigma]

Hey old bean, whats your upload settings for your vids, they're very good quality even at 360p. Much appreciated

[Dandaniels1978]

Hey I've just had a thought! The airlines are saying it's safe to fly after doing some test flights. Well....what if you drink and drive and manage to get yourself home without incident. Does that mean we can all drink and drive now then if the airlines are allowed fly after putting pressure on?

Obviously it has nothing to do with Profit does it?

[rotblaubasel]

Nature gets revenge!! HAPPY DAYS INDEED!!!

[yamatooutdoor]

boloks! i wanna go to Hawaii! mother fucker!

[Ichthys74]

ha me il vurcano irlandese ha rotto il cazzo!!

[jimbobeire]

@Ichthys74 Eyjafjallojokull non è un vulcano irlandese. È in ISLANDA!

[DrChitta]

the americans are prbly trying to figure out which terrorist organisation did this.

[nick945]

Really strange looking in to the sky and seeing no planes or vapor trails. Also a lot quieter at night.

[IAreCrazyChris]

Q. what's the difference between Cheryl Cole and the volcano in Iceland?

A. The volcanoes still blowing ash xD

[MegaHorse88]

Damnit I meant 2:16

[MegaHorse88]

2:26 I swear

[MegaHorse88]

Fart at 2:17 ?

[Bastard78]

Not trying to be childish here but did i hear a fart at around 2.17 ?

[DigiBiker11]

@Bastard78 Yeah, I hear that too, lol. I think it's probably his chair squeaking as he leans towards the diagram, but it could be a fart :D

[shardlow123]

My mate is stuck in Florida hahahaha lucky sod

[sarahwolfgirl]

well i wouldn't wanna be on a plane if the engine would mess up mid air. good job for cancelling the flights

[lolcatish]

This is F@cking G@y i missed my flyet because of this sh1t. One in 10 000 000 chance

[nordthernlights]

@lolcatish me too;-[ i suppose to be on Holiday now....

[lukabert]

@lolcatish maybe other countrys shouldnt be forced to suffer your presence, i think the ash cloud did everybody a favor

[ClanMacDonought]

Does anybody know why the planes couldn't fly slightly lower just to avoid the ash? I know it would increase fuel consumption etc. but otherwise I can't see a problem.

[FSXtorrentz]

if i look up i can see them

[scott2k44]

I live in northern ireland right on the north coast and we can see a little ash in the sky (its a very thin light brown cloud) and their is ash on our cars

[royeb63]

I don't doubt that volcanic ash can stop a jet engine, but what most people seems to ignore is the fact that the BA-flight in -82 was flying about 30 km from the volcano.

Europe is more than 1000 km away from the volcano. The ash cloud has been diluted substantially by the time it reaches our shores, and I don't think it poses any threat. KLM, Lufthansa and Air France have been test-flying with no ill effect.

My opinion; closing the airspace is paranoid overkill.

[NabsterHax]

@royeb63 If you look at the pictures (e.g. at 1:57) you can see the ash over the uk and in fact it seems heavier over us than over the sea. It's only just after it blows past us that it starts to disperse.

[NabsterHax]

@royeb63 Oh, and, think about how many planes fly in and out of the uk every day. Now, maybe only 1 in 100 planes would be affected by the ash, but that still adds up to a LOT of planes would.

[stephenstez]

@royeb63 could'nt agree more

[patsosas]

Very interesting expert

[Films4You]

Thankyou very, very much for explaining this issue

[ezasad]

perhaps the engines restarted at lower altitude because of higher oxygen partial pressure (helps with ignition) and higher air density (better compression ratio). Just a thought.

[culwin]

Take a boat.

[SPQRemperor]

perhaps you should do another channel about geology

[tk0145]

Very informative.

[ereg1300]

fascinating, I assumed you just couldn't burn the stuff in the clouds and it starved the engine. I never would have imagined that would be the better alternative, since you'd just sandblast the turbines until you dropped out of the cloud.

[wrnchhead76]

The other issue is silica (the glass). It can tear them up, and restarting would be out of the question.

[labrat882]

Just what I wanted to know :D you're great, always on with what's happening heh!

[spacemonkeyjim]

I would be interested to know if there has been an unusual rise in temperature due to the lack of high altitude pollutants, con. trails, etc from the jet exhaust similar to what has been hypothesized after 11-9-2001 in America when all their aircraft were grounded. Of course the ash itself may also have effect on temperatures, but there must be reduced air traffic around the world as thousands of plains are grounded in northern Europe.

[sussexpenguin]

you've got to love how Mother Earth can always confound Human endeavour.

[stebbislayer]

Just wait for katla which is 100 times powerful then eyjafjallajökull which is erupting now. katla's ash will probably go all over the globe.  Katla will probably erupt after eyjafjallajökull.

[clarkcolt45]

we should invent extradimensional planes that fly in another dimension then the ash (lol)
