Blade out test on a turbofan engine.

[myosat]

the question is: will it blend???

[jimnrel]

Its a shame that it didnt work in the QANTAS engine failure..

That was so close to total the plane.

After all the years you would think RR couldnt stuff up a oil feed pipe.

[Alracso]

well, tanks for the video, now i only need one video about the trouble shotting of the fire protection please

tanks

[GGGunitNextLevel]

If I get sucked in there I'll survive.

[tetramoo]

looks like my washing machine when i put my y fronts in!

[tman1gtsi]

what a waste of 600,000 dollars

[VkCuber]

@tman1gtsi not a waste, its important to test how that engine behaves in case blade goes off. if it explodes mid air it may result to death of hundred passengers. im so sherlock here :)

[Obsidian1985]

@tman1gtsi not testing this stuff results in wasted lives. They want to know exactly what will happen under every possible scenario when something goes wrong on a passenger aircraft. In my opinion life is worth more than paper, but I guess not everyone will agree.

[calvinblinkee]

@tman1gtsi The engine in the last part was 9 million pounds

[dave38x]

@tman1gtsi hardly. Clearly operational safety just isnt important on an engine which - if it fails - results in the death of a plane full of people...

[happyapple96]

the smoke detector just went off

[jetaimemina]

Can someone identify the music that plays in the middle? It somewhat reminds me of the soundtrack to the movie Sunshine.

[walkandlookup]

if the flight 232 had this the accident would not happened

[howaboutben]

The fan casing has layers of kevlar wrapped round it. This strengthens the fan case and reduces the vibration of the blade off. amazing work.

[Vitahero]

Thats one of the aspects, why jets are so save!

[bumech]

designing a containment case that succeeds to keep the fan blade within is an impressive work.

[flash4sa]

nice

[samoht1977]

quite impressive.

[mackat4ck]

My answers to your questions:

1)It's a fantastic engine that is efficient, safe and fast.

2)I actually prefer the low pitched roar the engines make on take off because it adds to the effect.

3) The purpose is not to destroy the engine but to test the effect of certain problems that may occur and minimalise the damage caused. With this knowledge we can make sure that the broken fan blade flying at 500mph won't break into the cabin and kill someone! (this has happened on older airplanes)

[XxCarnageX1120]

1) Because they are faster than the old propeller's

2) It's music

3)If I could destroy a jet engine any way, I would point the engine torwards the ground vertically and let it launch up until it ran out of fuel and came crashing back down.

[FALCO64125]

Alone, the thrust from a jet engine would not go in a strait line... but you knew that right?

[lexichronicle]

i bet they send the engineers on holiday the day they blow up their months of work :P

[spencnaz]

0:51 fries are done!

[snoopyloopy]

rofl lol

[adels1234]

ROFFFLLLLL that guy got scared hahahahhahahahahahhaah 2:02

[revorocks123]

OMG I just love the noise at 1:55!

[raptor22Tiquet]

i agree.. it is like music

[yotapact]

lol...... it's powerful!

[johnson2324]

it so boring for engineers when engine explodes at 2:01

[Cyan1902]

hahaha 2:01 the guy on the left side! :P

[HolyBlackJezus]

what the music playing in the middle, very relaxing

[ShuddupChip]

why not? its just simple safety testing, and you could find info about it anywhere...

[leifning]

yeah uh why?

[jammybizzle666]

yeah because terrorists don't know that exploding jets are bad?

[clof2001]

Ok. Drive your car the next time you need to travel across the globe.

[johanvandyk]

Why not? I find this extremely interesting! I work on planes and the technical side of the facinates me emmencely! This st truely remarkable!

[GUAlliance]

Nice... This is so Fascinating.

[alanwrollins]

Remember when the Delta Air Lines DC-9 threw a turbine blade through the cabin? It

[cweyer]

This was in PNS. It was an MD-88, which is technically a DC-9...

[Nrehder]

You know...There is a significant difference between blowing a blade out on land with the engine safely bolted down onto a secure platform and have it strapped onto a wing flying at 900km\h at 35,000ft. Shouldnt they take this into account?

[TheFerruccio]

They do.

[B171079]

How..? =o

[TheFerruccio]

They use something called a "factor of safety"

That is, they design something to take loads far beyond what might happen in an emergency. For instance, this engine was likely designed to take around 1.5x the force of a fan blade coming off inside of it.

Any additional loads introduced at speed will be minuscule compared to the blade coming off. They verify that assertion with calculations and simulations, along with actual tests to measure the loads at speed.

[tchiseen]

The engines are connected via 'fuse-pins', which among other things, allow the engines to fall off the wings safely should they fail in a manner which poses a threat to the wing. This means that if an engine becomes imbalanced and transfers enough load through its mount, the mount will fail and the engine will detach. This is to ensure that the wing doesn't get the extra forces, and the plane can still fly.

[bigred2989]

Doesn't that cause a balance problem when only one engine is expelled from the plane? I imagine that it would make it difficult for the pilot to keep the plane from flipping in midair.

[Heston83]

It would cause a difference in balance. The more noticeable effect would be the loss of thrust and drag on one side, creating a significant yawing effect. However, this is why there is a separate rating class for Multi Engine pilots. They are thoroughly trained on how to handle these adverse effects.

[tchiseen]

The rig on which this is tested is designed to exactly simulate what the engine would do in flight ( ie the vibrations caused ).

[scagliettileopard]

What engines are used in the clip?

[itmeng]

PW4000

[gcoochy]

This is a Rolls-Royce 535-E4 all RR engine turn clockwise

[tehflamer777]

Absorb it through the cuckoos? wtf

[KwantumPsyentisd]

0:54

you would think that they would turn off the smoke alarm for such a test....

you know, it kinda looks like an off balance washing machine

[conoba]

Never seen metal catch fire from friction, untill now.

[TheFerruccio]

If you're talking about the explosion, the fire is actually a result of the following process:

1: Blade comes off, slowing down fan and the compressor.

2: Compressor thus loses compression, which is maintaining the fuel/air pressure in the burner.

3: All that compressed fuel/air mixture in the burner becomes uncontainable and shoots out the front of the engine.

[tchiseen]

That is correct.

[WisdomVendor]

what a cool job to have,, destroying some of the most powerful engines in the world.

[legox50]

@WisdomVendor  -_- The GE90 is the strongest...

[Alpharius93]

@WisdomVendor And expensive too...

[scott82mar]

Is that the roll royce turbofans engines they where testing?

[greggerm]

It may be a RR in the first segment, but the engine on the outdoor test stand sounds (literally) more like a GE than a RR.

[greggerm]

Replying to my own post - the outdoor test stand is actually probably from the A380 test routines... so it very well could be a RR engine.

[kgrimnes]

It seems to be several engines in this clip. Just count the fan blades.... The first part has an engine with 28 fan blades. The test cell control room shown in the start of the clip is a Pratt & Whitney control room in Connecticut(worked there)probably the GP7000.,is a RR in the outdoor test. Discovery filmed that test in Nottingham,search for "A380 Blade Off Test"

[PeteRosenburg]

Safest transportation in the universe.

[clof2001]

it's tests like these that make me want to fly a plane any day over driving my car. Air travel is really safe, those engineers think of everything

[zauraliyev367a2]

not so safe at all

[RMZ280]

you're stupid. airplanes are the safest way to travel in the world. the jet kept al the debris in so obviously its pretty safe.

[greatbritainwba]

You are more at risk in a car than in a plane.

[mrdiamondback1]

@greatbritainwba Of course idiot

[napischu]

@greatbritainwba Unless there's snakes on the plane!!

[airbuscrazy]

2:06 Hyper-drive!

[roaming2]

May someone please tell me what kind of music starting on approximately 1:15? Thank you.

[Heli0doros]

new age

[themilksnatcher]

0;49 the fella detinating the explosion was way off the count!!! lol!

[gamerzipo]

stupid.hes supposed to use filter in front of it

[coldasiice]

Wow all this testing because of the dc-10 that crashed landed in sioux City

[clof2001]

They fixed that issue 15 years ago. This is a routine test that the manufacturers do on every engine before putting it on the market.

[kdraper2007]

no, they've been doing this since the first jet airliners were designed.

[Vasos77]

Wow! That's pretty cool. I prefer that this masterpiece of engineering is destroyed though, without blowing the rest of the aircraft. These tests are a necessity and very cool too.

[enrmur]

impressing

[symmetricalprofile]

What a kickass job.

[yogods]

What's the probability that this occurs?

[theflyinggal]

this is not retail..it's engineering

[UltraAwesomeChannel]

Shut up. Read the comment again and realise that your the one who is wrong.

[cyborgtroy]

This is not engineering, this is Sparta.

[slennxirothe]

Nice one :)

[grooveclubhouse]

wow now those people have a great job.

"so bill what we doing today?"

"not much chuck, just blowing up a multimillion dollar engine."

"again...i should have gone into retail."

[Rhenoism]

Run that by me one more time....I'm sorry did you say "one released fan blade can throw my car 100 feet into the air (upwards against gravity)?

That's some power there, boy.

[walkandlookup]

it hurts to see such a fine piece of engineering destroyed OUCH!

[MattTheRushman]

Hey thanks guys. Yes its very sad that these engines are destroyed. But it is kinda cool. :-)

[Reggae45s]

@MattTheRushman Youd rather not see 1 engine destroyed to ensure your safety?

[cjpatz]

That's an awesome job..

[000darkstar000]

OMG!!!thanx 4 this Awsum vid*****But it made me Sad,2C that Beautiful Engine Die.ok it's 4 science+it keeps us Safe.i just luv Engines,

2me they'r more than move'n metal parts.Who

feels the same way???

[deathhell77]

ME FEEL SAME WAY

[BJWTF]

i feel the same way mate!

[000darkstar000]

CooL:)mate,good 2see there r some of us real people left!i went 2SummerNationals,Syd Aust.8000hp-Top Fuel Gasers!OMG!!!Best time Ever!!!

AA-gas!!!NITRO OWNS ALL!!

[skipplet]

Speak English for God's sake.

[000darkstar000]

WTF!!R U ON???Dumbass!y do'nt U JFOADBAMF!lol

[Miiikkiii]

i do

i LOVE THE SOUND and the look its just amazing

[rahul1004]

The last one was from an A380 engine. SO AWESOME!!!!

[telepater]

Truly amazing and quite stunning....

[illeagl]

best part is at the very end where you see the turbine housing shudder and swell from the explosion

[buybygb]

00:49 was funny, the entire place fogged up and you could hear the person in the background say "WOW!".

[fortesimo]

he didnt say wow he was saying 1234 LOL!

[buybygb]

No, i ment after he said that.

[howardbeale1976]

I like how there are smoke alarms going off.

[RadiusRocks]

the last engine test was on the a380

[medfexer]

That was the best jet test vid

[102trafalgar]

That's what keeps us safe. Really awesome footage, thanks.

[naughty00e]

Looks like it cooked the engine. Bet that was a fun day at work.
