Jet Engine Animation

[MultiBrados]

Very simple, but effective mechanism.

[DrVitoti]

This is a very old and simple type of jet engine, nothing to do with modern ones.

[ozzyan123]

"as ancient hisory cause this is centrifugal jet engine animation. Not installed in planes since the 50's . Good animation nontheless" ANS: Many APU and the well known PT6 from pratt and whitney are still using impellers today. Good animation !

[Mubarak1947]

super.........

dont mis it

[fubleduck]

Looks like a centrigugal flow compressor

[orika001]

ok I have a question, I know this is dumb, but how do jet engines work? is it pulling the plane or pushing it??

[wolterh6]

Flawless animation. Excellent video! I finally understand clearly how turbines work :)

[nolifemerc]

can i be inside the camber for scientic resons when the engine runs

[akhilramesh10yt10]

thanxxxxxx



[TheMkgt5]

much crazy!!!!!!!!

[drazenGT]

animation is sucks

[DesignViz]

Thanks for the great animation! Visit the NXTutorials website for more cool tutorials on NX 8.

[chiefishere]

Nice. But is that radial compressor really used commonly in jet engines??

[1v1oCODoStatus]

Love the sounds of the turbine!

[ILSRWY4]

this is a centrifugal flow jet, not a axial flow jet. 

[vasanthbangaru]

simply great

[AmrAshraf93]

what is the time of rendering this video in 3dmax?

[MiniGeek31337]

@Ben Gaut

You're good

[vaneztax]

Excellent teaching aid, easy to understand and conceptualize the inner working of the jet engine. Thanks

[numaiprostiaaramas]

nice one dude...great work

[meterdatamanagement]

what a great animation

[giuseppe34297]

wow



[goblis623]

this is so cool

[knightrider1545]

now i know how a jet works

[Nikitos253]

where is the JFS? how you gonna start that engine?

[elibeli2595]

this is absolutely FANTASTIC!!!

[esrmafia]

the fuel burns when met the oxigen?

[180TheDragon]

its not that simple....

[pilotmonkey]

Nice work

[breedist]

Hi there you might have spare time from your job assuming you are not redundant one.Having made this you should see yourself asking for a promotion

[MrSoflash]

Very nice, did you use FumeFX for the igniting gases?

[matrixsueko]

the blue thing is air?

[amerdhiab]

Great!

[ULTIMATERACER18]

uhh.. i know ill sound like an idiot asking this but... how do the "low pressure fan blades" i think theyre called stay in place? theres nothing holding it in place in the diagram -_-????

[qtuong]

@ULTIMATERACER18 of course, there are bearings, but the author did not go into mechanical details, just the principle of how thrust is created

[ozzyan123]

@ULTIMATERACER18

right, but i guess this should be a one side impeller.

[0011STEALTH]

is that cold fusion?

[0noobcube0]

@0011STEALTH wtf? thats air and fuel being mixed and ignited.

[KarriKoivusalo]

Looks like the simplified turbojet illustrations from the late forties.

There should be air intakes on both sides of the compressor disc though.

[MartialDuartist]

WOW... I never realized it was that simple.

Wonderful example! :)

[MrRshelp4u]

backward turbo charger lol

[DoDzillanator]

nice graphics! BTW, does anybody have jet engine for sale? =D

[abcas1990]

@DoDzillanator its simple enough .. just make one :P haha

[DigitalBoy24]

Very very nice!!!!!!!!!!!!!!

[TechnicalMarkey]

Very simple animation, thanks for uploading!

[cun7us]

Could do with some commentary

[UnitedPebbles]

Jet propulsion is compressed air dejection...no longer a mechanical things since that involved a lot of friction and heat waste...purely efficient, of course with the assumption the medium is available...you actually won't have constant speed with jet propulsion. Rocket science is not really a science at all.

[Andreaslillfreakact]

Is there a elektrik engeine that rotates the fans?

[DanFrederiksen]

looks like an old engine design

[irvinmanohar]

I am wondering how the blades spin?

I know they suck, squeeze, bang and blow. But how does the blades spin? Is the a motor? or a magnetic field?

like in car engines, pistons turn the axle. but what turn the blades to make it spin and suck?

[Fent00zler]

@irvinmanohar In steady operation, the compressor is driven by the turbine. This compressed air is then mixed with jet fuel and ignited. The burnt gases then want to get out of the combustion chamber as quickly as possible (the gases undergo a huge expansion in there), so they flow through the turbine blades, making the turbine spin (like when you blow on a windmill toy). How the energy left over is used depends whether you have a turbojet, a turbofan or a turboprop. Hope it helps.

[juredddd]

Hey I am still learning so I got one question:

Would a jet engine should have more rotating blades not just 2 for sucking air and blowing or this is just basic example of jet engine?

[tjf4375]

@juredddd Yes, this is a much simpler design than the large turbofan engines we see on aircraft - the main difference is the method used to compress the air before combustion - in this case the front fan acts as a radial (centrifugal) compressor, pushing the air outwards from the centre, and into the combustion chambers. More complex turbofan engines use fixed turbine stages (stators) between multiple rotating fans, reducing in diameter and pushing the air backwards into the combustion chambers.

[ryanjohnsond]

Beautiful job. Top notch, pro!. The lighting and reflections are great on their own, but the other fuel effects are equally impressive. What kind of light set up did you use? Does 3D Max have a cut tool to create cross-sections or do you have to do that manually?

[GerbilEssences]

This is just a turbojet with centrifugal compression, most modern jets i.e. for airliners have a turbofan.

[EasyOpeasy]

centrifugal compressor. gases are slung away from blades by centrifugal force into the combustor.

axial flow compressor. gases flow axially through the engine

[davonizdashit]

what are the bronz looking things around the spinny thing somebody explain this to me

[Illusion2k]

how many RPM can do the newest jet engine ???

[spboike]

This should be taught in schools...

[BABarracus4]

@spboike it is in engineering schools

[thrax777]

@spboike as ancient hisory cause this is centrifugal jet engine animation. Not installed in planes since the 50's . Good animation nontheless

[ozzyan123]

@thrax777

Impeller are still used for some models today as high pressure compressor (last stage).

[ozzyan123]

@thrax777

Impeller are still used for some models today as high pressure compressor (last stage), specially for turboprops. lol I just say that because I'm actually studying this =P

[ozzyan123]

@thrax777

I think that some new engines still use an impeller, the PT6 from Pratt and Whitney does.

But in general youre right, that's quite old technology.

[ozzyan123]

@thrax777

Many APU and the well known PT6 from pratt and whitney are still using impeller. Good comment nontheless

[rapaceable]

i want that in my car!! :p

[tasman763]

this is a centrifugal compressor . most people expect to see an axial flow design .

[Pantbera]

Actually, the real turbine engines of passenger aircrafts look and work a lot more diffenent than these radio control turbine engine. These rc turbines are all based upon the very first turbine engines that were invented which were quite weak. From the 80's up till now very different types were invented. They have about 18 - 20 fans inside them and 5 - 6 turbine fans. The first fan in front has about 24 blades made with titanium. Each costs about the same as one luxurious classic family car.

[biscaygolfo]

that's a very simplified concept of what happens inside a turbine, the middle section of the turbine is missing...

[julikiman]

Beautiful engineering.........

[Rubdos]

Will burned :)

[limppimento55]

I still dont know how these friggin things work.

[getdown1983]

The relativ atom mass is to handel with (g/mol=x*10^-36) for the exactly molecularmass and so the exactly ratio.

Example: The molecular mass divide by the number of atoms and then to ratiomasses you want.

[TheNecrosisx]

Fantastic animation



[greatwhiterx8]

I dun get it.

whats there to dislike about this video???

Great job btw

[sazzonovjunior]

It all makes sense now!

[CrazyCHikcin]

that's a really nice animation

[MilindSabarad]

a simple, self explanatory video

[jasonbadler]

I think it's a little more complicated than that. Coll though.

[nextgapdotcom]

How does a jet engine lubricate its bearings? What kind of bearings are they?

[akinorhan5]

its like a turbocharger

[akinorhan5]

lol its like a turbocharger

[Narvarth]

Wow this is really nice. The quality is breathtaking.

Nice job. Thanks !

[Cowboy1O1y]

so the engine mixes jet fuel with the air (of which it has great amounts traveling at high speed) and creates a very 'pure' burn?

[rendermedia]

Thanks all for the comments, the software used is 3DS Max, its rendered using a renderer called Brazil by Splutterfish.

I really enjoy creating these types of shots, its a great way of explaining with simple visuals how a process works without over complicating.

If anyone would like to get in touch regards bespoke shots or projects for educational or broadcast please get in touch.

Many Thanks

Rendermedia

[assailant85]

@rendermedia can you do sth like this for a direct shift gearbox of a car please? :)

[PowerfulTechnology]

@rendermedia

How long time it takes usually to create like this animation?

[rendermedia]

It can usually take between 6 - 10 days to create a shot like this including a few rounds of changes etc.

[specal123]

@rendermedia it locks realy cool but it is al lot of work for just a very short video

[BenGaut]

Suck.

Squeeze.

Bang.

Blow.

[TimpBizkit]

@BenGaut All happening at the same time

[physivic]

@BenGaut

I think you forgot the 'yank' part.

[Nastyswimmer]

This is the centrifugal/radial jet developed by Frank Whittle, rather than the axial jet which is used these days. It shows the basic principles, but not the true detail of the modern jet engine.

[cr0c0p8]

Icy Hot?

[parus14032531]

It helps me a lot. Totally awesome. Thank you.

[mpd19666]

Great animation, its nice to actually see what your designing. And for those who are curious:

Thrust of a jet engine= mass flow of air*(exit velocity of gas from engine-flight speed) assuming the nozzle is ideally expanded, of course.

Yay for rocket science

[Mick280zx]

wow that is a very old turbine

[MDIVISIONRULES]

So a jet engine is that simple huh

[magnernj5]

@MDIVISIONRULES Modern jet engines are a little more advanced, but this is a good principle of a jet engine.

[crimsonjets]

@willwoodhouse secondary airflow provides about 80% of thrust only on big turbo fan type jet engines, where the first stage fan is a lot bigger then the core compressor. as for fighter jets most of the thurst is provided by the air flowing through the core (primary air flow)

[residentev1]

This is so cool. Awesome. Thanks!

[Teren1990]

nice work, thanks man!

[antoniopetrini]

WE DID NOT KNOW HOW DOES JET ENGINE WORKS... NOW WE DO!!!

[MarcosPaulista1000]

so good,great job!

[tsdisee]

Love this, when fuel explode in each chamber, how to make sure the heated air go to the back not the front.

unless you have a valve at the air inlet, it will close in every blow.

[laudiumWP]

I read that that part of the engine only suppies 20% of the thrust. The rest is generated from the air that goes around the inner edges. I thought that was really weird..

[cmla08]

Idiot's guide to jet engines; Suck. Squeeze. Bang. Blow.

[UfOjaCkal]

so jet engine are actually huge turbo?

[Nonsenseatbay]

Very nice and clean animation. Mechanical fly-throughs are some of the coolest animations.

Would make a nice project for a demo reel.

[MrSaqib140]

EXCELLENT ANIMATION!!!! REALLY TURBINE ENGINES ARE INCREDIBLE!!!

[MrSaqib140]

LOVELY INCREDIBLE VIDEO!!!! THANKS A LOT

[MrSaqib140]

THANKS A LOT FOR THIS ANIMATION!!! ITS REALLY VERY GOOD!! TURBINE ENGINES ARE NO.1.... I LOVE TURBINES RATHER THAN 4 STROKE OR 2 STROKE ENGINES!!!!

[SJWong100]

May i know which software you use to create this video?

[irvinmanohar]

this is a turbojet type engine i guess. 

[cobrachoppergirl]

I still don't get it. How come the combustion in the combustion chamber isn't pushing back out the air intake path equally as the exit path. And wouldn't it be a better design for a higher velocity engine to have the air coming in be accelerated, but go straight through the engine and out the back, rather than follow such a convoluted path? And eliminate as many high speed moving parts as possible. One of those blades snaps off, you've got deadly shrapnel killing a window seat passenger.

[MrNightware]

hmm what fuel can be used on this? :S

[jushal05]

really nice like your videos!!

[phadil]

Next time maybe you can make an axial compressor jet engine. It's what a majority of jet engines are today.

[sjmunoz]

where is the combustion chamber ?

[33049156]

awsome animatio. :) 

[egymedo2011]

greaaaaaaaaaat video thank u very much

[IIIgGeeksIII]

i still dont get what is spinning the rotor

[93blackstorm]

one of the best animations I have ever seen Nice Job

Please can you tell me the name of software you used to do this

[gryzman]

there's air missing in the middle part, with a bit that compresses it.

[zappaflorida]

i still don't know how the water doesn't get into the combustion chamber

[thehossman1]

compressed air directed into separate ignition chambers. very old technology.

[strassj]

I believe its old design of those turbojet engine? Look like it was used on DC-10

[gblpst81]

It's a very nicely rendered animation, but it's not a design that's used anymore in any aircraft that I'm aware of. Only the earliest jet engines worked this way. Modern designs use a more linear flow design with a multistage compressor. Sir Whittle would be proud to see his design animated like this though.

[sodafdublebareL]

Jet engines are easy, blue goes in, red comes out.

[digitalblue9000]

Clutch-starter interlock device start first fan, first fan take air to second fan.....

[zapbolt]

so how come planes don't have infinite energy? if so much heat can come out from the second end, can't they just make some extra fans for the purpose of heat only?

[airgunner12]

Ummmmmm, where are all the other component's like the compressers and such .. ?

[zredbaron240]

you can't make a simpler explanation of how a turbine engine works. full points.

[aliadinsr]

thanks for share this video, I will wait your next,,,i like it...

[qAyyUm]

i still cant understnd how airplane turbine works.

[ProzacR]

@qAyyUm In really simple way it just just third Newton law.

Engine emits gas backwards so all plane moves forward.

Most simple model is rocket, like fireworks. Just main difference that rocket uses other oxidiser and jet engine produces oxidiser itself by compressing air so it is cheaper and more practical.

[qAyyUm]

i still cant understnd how ariplane turbine works.

[agrogreenTV]

any text explaination?

[mestizo23]

Now I'm sure Impellers or centrifugal compressors are mostly used in turboprop airplanes.

[pollolocol]

@mestizo23 You are right to an extent. Small engines tend to use impellers or centrifugal compressors. Impellers are very good at compressing in a small space, but as the engine gets bigger, the impeller has to get big enough to handle the mass flow. After a certain point, it's too big to be practical so you end up getting into axial compressors.

[pollolocol]

@mestizo23 You are correct on this. This is because turboprops and turboshafts (helicopters) are small engines that require little airflow since they produce less power. Impellers take very little space axially. When you try to increase the airflow through the engine, the impeller has to be increased in size radially. This means it must get wider. Thus you have a very wide, heavy engine. At some point it makes more sense switch to axial compressors. (about regional jet size like the ERJ147)

[trueChaos23]

wow that was actually helpful in understanding the basics of how a jet engine works in a nutshell...

[kumpasmavra]

PAYŞAŞIM İÇİN SAOL GERÇEKTEN GÜZEL BİR ANLATIM HERŞEY ORTADA

[bhs117]

thanks for the video i learned something i didnt know before 

[quangluu96]

i have a question...........does the more air compression the more thrust it produce?

[mestizo23]

maybe - The compressor is used to compressed the air but keeping it below the speed of sound and when it reaches the diffuser it's velocity is decreased but its pressure increased but more stages do help in performance and also some air is used for cabin pressure or heat air, for wings & engine de-icing etc. Remember altitude and where the air is less dense benefits different engines. Turbofans perform excellent at certain altitudes so do turbojets. You want more thrust Afterburner is the way.

[willwoodhouse]

@quangluu96 not quite... although some thrust is gained from the compressed air which is ignited with fuel and pushed out through the secondary fan, most of the thrust comes from the air which is then pulled through by this fan and is not involved in the combustion process. (I think this air causes about 80/90% of an engines total thrust on the most efficient models although im not entirely sure)

[k0nn0r]

@willwoodhouse It's true that about 80% of thrust comes from the fan in modern engines, but only during take off at sea level. At altitude, the large area and high inlet speeds cause a lot of losses in the fan. There's a vector addition going on between the rotational speed of the fan and the inlet speed which causes the fan to "see" supersonic speeds. That creates a lot of losses and makes it difficult to extract work from the bypass stream at cruise, so thrust only comes from the inner stream

[pollolocol]

@willwoodhouse You are correct. The fan (we call it bypass flow in the industry) provides about 80% of the thrust in modern jet engines. The more we can pull into the bypass flow, the more efficient (generally) the engine is. Note for terminology: the part that does compression - ignition - expansion is called the CORE and the air that goes around it (through the fan) is called the BYPASS.

[collierman57]

On the animation shown of a simple turbojet, air drawn in at the compressor all flows through the combustion chambers but not all of its oxygen content is used up during the combustion process. High bypass ratio turbofans direct a vast quantity of air around the core jet engine which I think is what you mean.

[Umbot786]

@willwoodhouse

Yh your absolutely right mate

Ive been doing research for my interview at rolls royce, the air that is being sucked in and used as thrust is known as bypass thrust, the air the is compressed and combusted is known as core thrust

The type of engine is a turbofan, then there is either a high bypass engine which gains 80% of its thrust from bypass and the other is a low bypass engine which gains most of its thrust from the core etc

[donotwantyoutoknowit]

@willwoodhouse: not in this engine. it's the first generation, not a turbofan. in later generations yes, but here there is no bypass of air. It's the first whittle engine. all air goes through the combustion chamber. In all first generation jets there were no bypass. Anyway, the actual energy gained and produced comes from the combustion process and yes the more pressure, the more thrust you get (pressure ratio).

[doug65536]

@quangluu96 Not really. More fuel makes more thrust, but it also increases the turbine RPM. Also more fuel increases exhaust gas temperature (EGT). Jet engines all have a limit on RPM and EGT. When flying in the cold air at high altitudes it all changes. Typical jet engines have enough power to destroy themselves if you went full fuel flow at low altitudes, but full flow would be fine in the thin cold air at high altitudes.

[pollolocol]

@quangluu96 It's not directly related. More air compression results in more efficiency. So, for the same fuel flow, you would get more thrust but that is due to the fact that your cycle is more efficient.

[Jonas645silva]

woooww that's beautiful!

I love jet engines

[pengy44]

so what is filled in the space between the combustion chambers and the shaft? is it just empty space like it is in the animation? or is it filled with electronics and stuff?

[pollolocol]

@pengy44 It's "empty" space. In reality, we use this space to route cooling and pressurization air to be used elsewhere in the engine. The electronics and hydraulics are all mounted to the case of the engine, outside of where all the action is happening.

[kenupcmac]

can this use for a jet roadbike? and how much would it cost to get 2?

[COD5252]

why there are 16 chambers to burn fuel,why not 1 or 2?

[COD5252]

why there are 16 chambers to burn fuel,why not 1 or 2?

[mifan93]

ok, i sorta get it...

so the cold air intake turbine spins because its connected to the exaust turbine?

so from one spinning it turns the other?

[spectre55x]

Not bad for a centrifugal flow compressor design. Not very common on med to large sized jets, though. Give me a good ol' 16 stage axial flow design any day! We test Pratt J75s all the time. A "straight" turbojet putting out more thrust than an afterburning TF-30. Now that is power!

[nickabokka]

i love these animations. amazing break thru for education

[JonThm]

Jet engines do nuclear fusion from all that steam!

[guitmarc54]

a 3d image is worth a trillion words....

guitmarc54

[AndrewLLFrazier]

@guitmarc54 if a picture is worth a thousand words, then a 3d image would only be worth a million words.

A 4d (3d animation) is worth a trillion words.

[ChildoftheKoRnf9]

Looks kinda cheesey on the model but the flames and the airflow look pretty damn good. Should hire this guy for the syfy channel and actually put out some decent quality, lulz

[jep0rox]

mkuki no but you can use carboniced paraffin wax (who new) lol me

[doromanekia]

no the axial turbo engine wasn´t geman invention actualy french and then british! the germans made it practical. as allways.

[doromanekia]

the germans didn´t invent nothing just copied! the british and french invention!

[ccx91]

this is a very simple single spool engine with a centrifugal compressor. modern jets usually have multiple spool engines with axial compressors which are generally more efficient

[Raleigh3000]

Is there a downloadable version of the video?

[PistolPete2]

This is a turbo jet engine. They are used mostly on military aircraft. Most commercial jets use turbo fan engines which has a fan disc in the front which bypasses air around the engine and creates extra thrust. Some commercial aircraft use turbo prop engines. The shaft in front of the engine turns a propeller after going through a gearbox.

[f1837]

(nowadays military engines are using turbofan)
