@TheRealdpb95 Usually this type of problem is caused by not enough RPM when the fuel is then running into an engine. Fuel gathers in the combustor can and when it lights it spits out all the other fuel. The bad thing is it can destroy the combustor can inside of the engine.
Someone did not windmill the engine without ignition before attempting a start. The preservation oil needs to be ran out of the fuel system before starting. Then you let the engine run down and then attempt a start with ignition. When I was in the Navy we would light off the preservation oil at night once in awhile to get crash crew fired up. At night, as in this video, it is very brght. During daylight you would barely notice. Really not a big deal unless you get caught doing it.
@jlangfel free flames burns at about 400° celcius, normal egt on 737 800 is at about 600°. anyway it is perfectly normal to see some flames at first start after a period of reparing or complete mautention. it is caused by the protective oil coat on the new components like compressor and turbine blades that leave the surface due to centrifugal acceleration of the moving parts and the hi speed air flux by the elements. nothing to warry about anyway.
@tomcatmaverik Great stuff explaining the science behind this....I'm just more worried about your spelling... "nothing to WARRY about!" I'd be off the plane this instant if I'd know you're fixing it!
@tomcatmaverik So Sorry...I assume most of the time everyone speaks English! DuH! My apologies. *Note to myself: must learn some Italiano* Bravissimo! (that's the only word I know!) :)
So what was it - a major internal fuel leak ? You can see the raw fuel coming out of the back. Does this engine have multiple stages of injectors ? Were they all stuck in the ON possition ?
Oh yeah - if the camera man didn't know - he is an idiot - if that wing got torched through to the fuel tanks - BOOM ! ! ! Was it worth standing around video taping it with that much dangerous stuff that could have happened ?
If you listen closly at 39 seconds you can clearly hear the sound of the engine shutting down, probably the crews response to the flame out on start up. The flames shooting out is very abnormal.
I only work on cars and still feel a bit apprehensive on that first startup of a refreshed engine. I can't even imagine how those mechanics feel. I think I'd be sick!
Yep, that's perfectly normal, nothing of concern. When the engine has been repaired or stored for a long time, there may be a little oil or fuel that poured into the engine and gets burnt during start up.
thats not possible, and that model doesnt exists, 737 has many structural and aerodynamical limitations that not allows this aircraft to fly not even beyond 0.9 machs, and commercial airplanes have no afterburners with the exception of the concorde ;)
@syafiqdell no it is just a blow out this hapins wen there is some oil in the turbine coz on a new turbine thay spray a thin layer of oil to keep it all loobed up after the test and that test all turbines b 4 thay put it in a plane
someone either forgot to push the circuit breakers in and there was fuel pouring in the engine and then it ignites nice flames out the back, they try and avoid things like that as the turns turbine blades to charcoal
The engine has just been overhauled. The white smoke you see is oil smoke that later on ignites. BTW: those turbine blades can handle some temperature ;-) it gets up to 1200°C @ the high-pressure turbine section...
thats a wet start. i have minature turbines that act in the same mater when they are started. only the first start this happens. the next time will be a normal start. they needed to prime the fuel line so it may have got a little more fuel then normal thats the flame you see..
I'm a fully qualified marshal and I have never seen anything like this in my job. I have been trained that in any situation involving fire on start up then we are to instruct the flight deck to shut down it's engines.
Exactly (no offense), but a marshaller. Of course you would not see this. This is a maintenance run, not a pre flight run-up. I am a fully qualified flightline engine mechanic in the airforce and all engine that get shipped from depot or issued out of a engine backshop are preserved with oil in the fuel system when prepped for shipping as a means for corrosion control. Whenever you recieve an engine, on most frames, the only way to purge the engine is by means of a dry motor//wet motor process
And if they shut down their engines on your instruction, then they're not going to put out the fire. They have to cut fuel, and continue to motor the engine to blow it out. This is a pickled engine starting up.
It's just a preserved engine run (fuel system preserved with oil for engine storage). it's perfectly safe and is not seen by passengers, No maintenance run is done with passengers on board. The threat of the flame lighting the skin is very low but there is a possibility. That is why there are fire bottle out there and sometimes the fire department during pickled runs. Relax. lol
@mushmouth1981 I've been an A&P mechanic for 25 years and I've seen LOTs of engine changes and I've NEVER seen this before. If the engine torches it could overheat and when it trends hot we shut it down before damage. The fuel tanks could have blown up because of the flames in this video. The flames could have damaged the composite panels on the wing. There is nothing normal about this run. Yeah, you wet-motor...but then you dry motor to clear excess fuel...NOT blow the plane up.
jet engines do not operate a mixture. The more fuel you add, the higher the RPMs. Thats why jet engines have so much control over RPMs, because if too much fuel was added accidently somehow the engine would simply blow up. Thats why jet engines are so great, they're so simple.
New or overhauled turbine engines always have the oil and fuel systems preserved with MIL-L-6081C, Grade 1010 oil. They always torch when they are started for the first time. This is common,
Oh come on man, I'm an a&p mech for 14 yrs. I've seen a LITTLE flame, but that was sick! Scorched the underwing? Plus glad the football panels arent leaking fuel !!!!! HA HA A
Yeah that's usually what most of the newbies we get in out shop do when the see an initial engine run on a preserved motor, THEY RUN!! That shit is always funny as hell. As long as the idiot does not grab the fire bottle, we're ok!!
This comment has received too many negative votesshow
I don't think I want to get on that plane. I don't care what everybody says. Driving is safer than flying. If your car stalls, you're not going to fall forty-thousand feet.
Funny how the people in the windows were looking out the window. ( I guessed they were nervous.
Nice way to warm up the fuel in the wing section. Am I right that the APU's ( Auxillary Power Unit) just helps get the engine started, plus some other things.
APU is off during flight, it's just an engine burning fuel and doing nothing!
Most aircrafts don't even allow for the use of APU in flight (because of the air intake), and the ones that allow, it's just for emergency (in case of one engine out).
Even so, it depends on the company procedures.
lepape2: The sound you hear after engine #2 start is either the spooled engine going to idle or, most prob a GPU (Ground Power Unit) instead of an APU, they make a hell of a noise!
On a B767 you start APU after landing, but on a A330, if I recall correct you start APU during approach (forgive me if Im wrong.. PSS checklists.... 3 years ago at least).
Auxilliary Power Unit... The smaller Turboshaft turbine engine (in the tail compartment) that you start in order to power essential systems like AC power, hydraulics (work with AC power), Air conditionning, etc. You use it to start the other two engines. I'm not totaly sure that you have to shut it down once the main engines have started and are stable. In fact... i'm wondering.
hot start? mabye its more like a "wet start" with things like the solvents and hydrocarbons in the assembly lubricants being heated to vaporizing point, passing thru the combustor, then, well, combusting!
Yeah, wet start indeed.. we called them hot starts as well.... Most likey it was a new engine full of preservation fluid (thats how we got them) i.e. the hydrocarbons as mentioned above.. combusting lol.. makes for a righteous scare for new personnal and one hell of a laugh for the old timers watch the newbies run..
Well, a wet star is when you don't have an ignition because of the combustion chamber being flooded with fuel.
If it eventualy starts then it will become a hot start because you had ignition with a flooded comb chamber. You see it easly because of the increase in egt.
This video i believe its not one or the other but just the burn of same preservatives deposit after the maintenance at the exaust itself, otherwise the pilot (or mechanic) would shut the engine off.
EGT will increase anyway. A hot start is when the temperature exceeds EGT limits. A pilot would not know he had a tailpipe fire unless the engineer on the ground told him. The actual story is the engine was wet cycled and they did not dry cycle the engine to dry out the core area, hence why you have lots of flames. The website on the video might give you a clue.
Nope. They manufacture all the rotating hardware larger than it needs to be so that the parts size themselves perfectly and uniquely. Each engine sizes itself. This is why you can't replace hardware between engines sans reworking the part back to its correct pre-installation size and letting it re-size itself.
Wow, that was an interesting theory. Who manufactures engines like that? Russians? Because that is not the way it is done in the US. The this vid is a preserved motor (oil in the fuel system) Think about it, if the motor was turbine or compressor was rubbing, you would get sparks of metal comning out, not flames.
IF it's a first start after a hardware replacement, this is no big deal. What you are seeing is the engine "right-sizing" itself so that it will work. All those sparks are from hardware inside the engine rubbing against other hardware and throwing all the "rubbed" material out the back! No big deal but fun to watch!
The thing that looks like an engine in front of the wing, well it's not really an engine, that is the motor for a Star Wars Pod Racer, that they are delivering to Tattooine for some kid called Luke Skywalker.
Its probally a start after a wet motor. Just burning all the fuel off that was in the jet pipe. Good vid.

If it eventualy starts then it will become a hot start because you had ignition with a flooded comb chamber. You see it easly because of the increase in egt.
This video i believe its not one or the other but just the burn of same preservatives deposit after the maintenance at the exaust itself, otherwise the pilot (or mechanic) would shut the engine off.

EGT will increase anyway. A hot start is when the temperature exceeds EGT limits. A pilot would not know he had a tailpipe fire unless the engineer on the ground told him. The actual story is the engine was wet cycled and they did not dry cycle the engine to dry out the core area, hence why you have lots of flames. The website on the video might give you a clue.

That CANNOT be good for a wing full of fuel can it?

It's a good idea not to let the passengers see that before boarding.

It take very very long... because Kazahkstan is big.

Nope. They manufacture all the rotating hardware larger than it needs to be so that the parts size themselves perfectly and uniquely. Each engine sizes itself. This is why you can't replace hardware between engines sans reworking the part back to its correct pre-installation size and letting it re-size itself.

Wow, that was an interesting theory. Who manufactures engines like that? Russians? Because that is not the way it is done in the US. The this vid is a preserved motor (oil in the fuel system) Think about it, if the motor was turbine or compressor was rubbing, you would get sparks of metal comning out, not flames.

IF it's a first start after a hardware replacement, this is no big deal. What you are seeing is the engine "right-sizing" itself so that it will work. All those sparks are from hardware inside the engine rubbing against other hardware and throwing all the "rubbed" material out the back! No big deal but fun to watch!

so wait thoes things do that the first time the are started so that they will work proerly what i just seen is compleatly normal?

What am I looking at here? How does the engine end up in front of the wing?

What you are looking at is your computer monitor.
The thing that looks like an engine in front of the wing, well it's not really an engine, that is the motor for a Star Wars Pod Racer, that they are delivering to Tattooine for some kid called Luke Skywalker.
The real engines are inside the wheels.
Airliners are now all electric.

They did not do a depreservation run to get rid of the preservation fluid in the fuel system..
