pt. 2 of 3 Turbofan Jet Engine failure recognition

[josso1]

IBPCS - Instant Bird Pie Creation System

[lightpaws25]

They missed one possible problem with severe engine issues like that. In some noted cases the engine came off the wing it broke open the Hydrolic systems.

[harrier331]

is this vid ment for pilots

[litrboxsndcstle]

Cool vid and it's pilot friendly...Keep positive control of your coffee and look for red light. Got it!

[madisonelectronic]

They always have crapometers in airline pilot seats now, but we have had them in private planes for years. They are called Hanes and Fruit of the Loom.

[hillberg100]

Like the A-380s engines one blew,and the other didn't shut down, P.O.S.

[hrbear]

Excellent video, but where are the parts 1 and 3?

[vindaloo9]

spill my coffee?? More like soil my underwears!

[azmanic]

sorry can i just explain to the people who dont know alot abut planes........ go

when the engines bang w000000oooooooooftttttfttftftt­fttf your screwed

[circusboy90210]

turbine surge occurs how often?? on average.

[WildBuck007]

If this rides a rocking don't come a knockin XD

[faffaflunkie]

So that was what that sound was. Thanks for posting this one. These things don't fly themselves, you know.

[Welljusthi]

how did i get from 600hp trucks to cummins engines to this???

[1982FMJ]

can deicing fluid be a danger to jet engines if sucked in to sensitive areas over a period of time or applied by somebody careless. Have there ever been cases of airplane crashes atributed to carless decicing employes at airports who decided to rush the job or was having a bad day. I suppose pilots must sometimes wonder whether or not every airport groundworker is trustworthy and not likely to make mistakes

[ryder3939]

since ur smart,can u tell me where the mixture switch is in a boeing 737

[Metromechanic]

@ryder3939 right next to the cross fader, in between the turntables....:P

[plugs313]

@ryder3939 Welllll, everyone knows it's on the F/A's panel... heh heh heh!

[mazithaboss]

*this is the Captain speaking, If you look to your left you will see the engine going in circles.....Hope you all brought your swimming cloths, thank you for choosing Jetblue. :]

[ryder3939]

3:21 the thrust is retarded if it exeeds the EGT

[spilot14]

@ryder3939 cause its retarded. retarded=slow. but nevertheless, hahahahahhahahahhahahahahahhah­aha.

[wfravel18]

Good times being in the shop next to test cell when the engine would stall...

[justforever96]

This is pretty cool. I can't believe the flex on the accessory mounts...I take it that they're attached by anti-vibration mounts or something? Hopefully once and engine is subjected to vibrations like that, it's replaced afterwards! For that matter, I never expected the engine pods themselves to have so much flex. It makes sense, it's just odd to think how frail a plane really is. A 747 LOOKS like a damn granite mountain, but it's actually proportionately weaker than a Cessna.

[srsebd]

what is "EGT"?

[SleepyTito]

@srsebd : "EGT" is Exhaust Gas Temperature; It's one way to measure engine temperature. Some manufacturers use Turbine Inlet Temperature (TIT), or Inter-Turbine Temperature (ITT). The difference is where the temperature is taken, and limits are set accordingly.

[Iketh28]

@SleepyTito EGT is NOT a way to measure engine temperature... it's an indicator of the fuel/air ratio and how they're mixing and burning

[SleepyTito]

@Iketh28 You are correct in regards to a piston engine, but in a JET it's a measure of the temp and health of the turbine section. Specifically, the ratio between EGT and EPR indicates how efficiently the turbines are extracting energy; as an engine gets older it typically takes a higher EGT to achieve the same EPR. Saying "engine temperature" is a simplification but with no other direct indicator in the cockpit EGT is the only way for us to determine if an engine is running "hot".

[justforever96]

@Iketh28 Piston and jet engines are very different. Fuel/air ratio is only important in gas-piston engines because it effects the point at which the fuel detonates...to early, you get "ping". With diesels, it doesn't really matter what the mixture is, since the fuel isn't injected until almost TDC. Excess EGT on a turbodiesel can melt the turbine; same applies for jets. Jets not only run a far lower comp. ratios, but they have a "continuous TDC"...fuel is always injected AFTER the compressor.

[offspringfanman96]

@SleepyTito LOL TIT

[monimstarfox]

@SleepyTito

rofl we are learning all that in school :DDD

its freakin awesome to see something and understand it

[zcg3]

@srsebd You are ALL wrong! EGT is to measured temperature of the "EG"...you only have to decide if you want to take it by oral means or anal means.  Good luck!

[faffaflunkie]

Believe me. If this ever happens you will shit.

[Guilland23]

For a few minutes I felt like I was at the Pilot School.... So nice. A dream come true on Youtube.

[happydappyman]

the thrust lever should be retarded lol

[schlusselmensch]

Well, the shock of compressor stall can be duplicated in the sim but most everyone chooses to forgoe the friendly whack with a spruce wall stud.

[justforever96]

@schlusselmensch LOL. I think you should clarify...it's more like someone smacking the back of your armchair really hard with a 2x4. A jet liner is a pretty big plane, lots of room to absorb the shock wave. In a jet fighter, on the other hand....

[cachorrao00000]

muito bom esse gmp

[CarbonFiberSpoon]

3:22 lmao

[qiplayer]

a must have video, yeah actually the last time I shut down the wrong engine, this video will be a great help in case we steal another 747

[gigaboat]

Fly the plane first , work the problem second .

[whatuwantmom]

they make engines that can take 3/4 of a ton of hail and still work properly, id don't thinks birds are messing us up that bad any more

[schlusselmensch]

@whatuwantmom Capt. Sullenberger might have something to say about your theory.

[justforever96]

@whatuwantmom But hail melts once it gets into the engine...bird pieces don't. As long as the compressor blades survive the initial impact of the hail, it comes out the other end as water vapor. Plus, a bird like a goose has significantly more mass than a hailstone (usually), and at the speeds a compressor blade is moving it might as well be a stone (like hitting the water at 100mph is like concrete). So all in all, a single 20lb bird has a lot more damage potential than 3/4 ton of hail.

[TruthSeekinOne]

They forgot to mention extreme angles of attack can cause surge too, but most modern aircraft have systems to prevent this.

[xNumb3rs]

@theuserofmynameisme why u shouldnt shut down the engine then? sry didnt get it...

[GravityMuse]

@xNumb3rs If you dont shut down the engine and just idle it, it will provide less drag on the aircraft. Also, an idling engine can still provide power to other systems.

[tubestick00]

its a good thing the iraqi government sensors the internet in their country.

[JestAnoutherPistol]

i had the youtube transcribe thing on and in text it said apple pie

[seaboo143]

0:20 look like somebody is fucking inside the engine.. LOL :D

[authmaax]

slow mixture ECU adjustment  ...

when exiting a slighly higher ground air pressure

and air moisture level

man the engines wiggle a lot in normal operation

[federalfsx]

Thanks. Very helpfull

[unambitious]

Omg why would anyone watch this unless they were being subjected to it in an AF class room. *shakes of horrible flash back*

[airboy1997]

i will never fly airfrance again

[ManniMann1986]

you'd be surprised about what makes an "info-freak" tick... :P

[KartKing4ever]

this looks like a flight training video

[Lunarlaserranging]

these pieces of technology are so complex and there are many computers onboard airplanes these days that control the systems. im not one of these people that thinks piloting is all computers because it obviously is not but many of the systems have alot of computer controlled bit that have room for problems. the more technology you have the more to go wrong.

[b3gunkid90]

i hope these birds realise how much trouble they cause us

[04mittald]

@b3gunkid90 yes but its good that planes fly at higher altitudes or the jet engine would be like a blender for birds

[domokid]

@b3gunkid90

I wish more people realized how much trouble we cause them.

[98209276]

they say plains are safer than cars but when you have a car accident your on the ground when a plain breaks down your like 15 hundred feet in the air

[MBM001]

its a "Plane" and only 15 hundred feet??? try 41,000 feet

[SPARKYBLOKE99]

him say 'like' me say approximately

[justforever96]

@98209276 It's "plane". And the "car accident" rarely happens at 1,500ft (or 41,000ft, either). The "car accident" is when the plane reaches 0ft...and hits the ground. And planes are only STATISTICALLY safer than cars. If every person who traveled by air suddenly had to fly 2-4 people per plane, times 100 million travelers....the statistics would suddenly become QUITE a bit worse. And that's not accounting for the fact that commercial pilots are the best, while cars are driven by shmucks.

[schlusselmensch]

@justforever96 Hahahahaha, sit in the pointy end long enough and you'll cross paths with more than a few schmuck commercial pilots! In fact, the ratio of arseholes to good guys/girls is about the same as in any endeavour.

[justforever96]

@schlusselmensch Actually, the tail-end of most commercial jets is more "pointy" than the nose, if you don't count the stabs. But I'm not sure I follow your comment...what does that have to do with what I said?

[schlusselmensch]

@justforever96 You claimed that cars were driven by shmucks (it's "schmucks", by the way) and that commercial airplanes weren't. There's more than a few schmucks driving commercial aircraft, rest assured. And the "pointy end' is always the front.

[justforever96]

@schlusselmensch Oh, I know that "the pointy end" means the front, I just think it's funny that it's not really accurate. I know that navy pilots used to joke that the A-6 Intruder was "pointed on the wrong end". In that case, it was pretty obvious. As for shmucks in the cockpit, I'll bet the most schmuck-ish commercial pilots are interesting, intelligent people compared to civilian Shmucks. I mean, if pilots handled their planes as badly as some of the idiots on the road...jeez!

[willie14n]

haha go to 3:19. lol

[KartKing4ever]

@willie14n so imature but funny

[8XxMvMxX9]

lol!

[seanrosedotcom]

"...continue to fly the airplane..."

They have to tell you that?

[Lunarlaserranging]

you don't think like that. This is for people training to be pilots.

[fritschep505]

loss of engine thrust will produce yaw and spill the coffee in your cup and of course screw up your day! LOL

[simon1000]

@fritschep505

Gin and Tonic in my case....lol

[CSIS25]

About 95% of this i have no idea what he is saying but, i like to think i am learning to fly by watching this lol

[nlqphf7ybx]

Al Gore is a great narrator.

[fuge000]

NICE

[sstroh08]

a compressor surge is sort of like a car engine backfireing its nothing to be scard of it usually just goes back to running normal after it happens

[coolfly005]

come on every multi engine plane is designed to survive without one of its engines but i cant say that you would exprience the smoothest landing you ever had lol... its nothing to be afraid of

[RacerXGTO]

These comments are funny. You guys are little girls!

As long as you have one or three other working engines, you're golden.

[richu27]

I have never known about a person who will laugh at those situations. Wierd....... Hmmmmmmm.

[PanamaIsMyName]

Better not to fly, man.

[Flyingfast79]

The 747 take off was actually a test flight for the 777 engine to test engine surge.

[SubaruB4RSK]

Yeah that's because it had compressor stall.. the explosion would cause the whole engine nacelle to shake.

[AznAviationDreamr]

sadly, ALL aircraft do have flaws, mostly engine failures, its best if we prevent that from happening... nice video :)

[randommagnum]

Man if I was on a plane that started doing that, I'd be CRAPPING MY PANTS.

[obese1konobe]

Surges are not dangerous but certainly get your attention.

Just throttle back on affected engine normally clears problem straight away.

Often caused if cold soaked engine producing high power.

[robf93]

Surges can be dangerous if not handled properly. A JT8D was torn apart in flight due to heavy rain and the pilot's failure to retard the throttles. When they raised it on it's side, twisted and broken blades fell out!

[ymanganelli]

WOW.. awesome video:)

[zeesham13]

don't you know retard means slow.

[PurgePhantom]

What is this for? Pilot training? I wanna be a pilot some day but I guess I gotta go 2 college first... : P

[szplaya68]

id got 2 michigan or eastern mich.

[Roserade]

the thrust lever should be retarded to allow the engine to recover?sounds weird.

[MrBenCleaver]

if your car engine makes a loud bang, would you put your foot down on the accelerator to rectify the problem?

[Roserade]

no.

btw,I don't drive a car.

[L00peey]

loool

[adam3176]

OH Thanks ... Next time i am in my 767 ill try these out...

[sergeantsolo]

5:45......imagine looking out the window and seeing that shit.

[ethicomm]

Yes, I'd be soiling myself if I saw that.

[volodymyrm1]

stall/surge whatever, as a gear head I would just called it a backfire

[lejink]

a backfire is a completely different condition, when the airflow through the engine is abstructed the fuel isnt completely burned within the engine causing long streams of flames out of the back.. thats a backfire

[volodymyrm1]

haha oo well i am a car guy so I don't know too much about airplanes I know only basics how it flies it's all i need to know 4 now LoLz

[keeevan]

well actually a backfire in aviation is not what you would expect. Backfire is when the explosion happens back through the intake and afterfire is what you would call a backfire if you think about cars.

[lejink]

the explosion is an engine surge.

[Iamfukenripped]

unless that alien thing from the twilight zone was maessin with the engine ;-P.

[msezza]

No... completely different *rolleyes*

[koolbossjock]

WHERE IS PT 1??

[pigpenthegreat]

Read the info in the top right dufus.

[syeager9]

DeeJayMiikkii, actually they are talking about windmilling of the fan. And in case of damage it can be unbalanced and at certain RPM can get into resonance and cause dangerous vibration. The engine itself can be shut down. But the fan will rotate. Changing the airspeed will change RPM and may reduce the vibration. Fan is usually driven by the last turbine wheel(s) in the engine. Modern turbofans usually have 3 shafts that connect stages of turbine wheels, compressor sections and the fan.

[indyboom]

yes spiking of egt is a quick reference and also the fuel guage will follow rpms.

[PorkyPiggles]

Vibratory? Is that a word?

[bigtig4life]

Yes, it is.

[PorkyPiggles]

It was a rhetorical question, but thanks anyway.

[fayik123]

frightening to think of over the atlantic

[harshil69]

you got that right haha..ad rather be haunted

[thibaulthalpern]

What is "windmill speed"?

[SleepyTito]

Windmilling is when the engine rotates as a result of the aircraft's motion through the air (relative wind) rather than by its own power. Like blowing on a pinwheel. "windmilling speed" is the speed at which the airflow is sufficient to do this.

[kydrythm]

Woah, that was pretty nuts. Listening to the narrator was fun.

[eugenealive]

4:35. The thing, that i never wanted to see. I would shit my pants if I saw it ))

[Fullperson]

oh jeeze worst fear

[Noobixide]

This was very interesting to watch just for general education.
