  • Turbofan Actually.

  • @ScottsdaleBlessed A turbojet engine comprises the "core" of any turbofan engine.

    The Daimler-Benz DB 670 was the worlds first turbofan in April 1, 1943.

  • @paullees557104 Yes, thank you for proving my point, Whittle did not have a working engine until 1937, after von Ohain did.

    Whittle's 1930 design that was patented was never built.

    No, Whittles design was a gas turbine converted to use as a turbojet, as we know the gas turbine had already been invented. Whittles engine was not the first turbojet.

    Wrong, Whittles first engine was th 'WU' followed by the 'W.1' at 850 lbs of thrust.

  • Prat and Whitney has a new turbo fan engine which has a reduction gear (first for a turbine engine) .. they said its 20 percent more efficient than any similar engine on the market... Airbus dint believe it.. so they tested it for themselves and found it to be true.. now they putting the engine on their 320s and calling it N.E.O -- New Engine Option. Boeing is doing the same with their 737s.. looks like Rolls Royce is about to get a run for their money..

  • Comment removed

  • I thought the turbine generates work to run the fan and compressor?

  • Anyone noticed the A340 at 1:34 has its No. 2 engine different from the other 3? XD

  • @WhiteKestrell they wanted to test run the new engine they were putting on the A380 before its launch..so they put one on the A340 and used it as a test platform.

  • 2:32 I wonder how they get that section in the centre of the blade in there.

    It can't be machined into place, but using a core surely can't be precise enough alone.

  • @doktorbimmer So what is being shown in the CAD drawing at that point in the video?

    It looks like some kind of inner void or stiffener.

  • @lexichronicle2 Well, its not a CAD drawing.. more like a generic aniamation. Modern high pressure turbine blades are air cooled with air bypassed from the compressor stage, the christmas tree is hollow and air bleed holes allow air to flow through and around the blade. Check out this guy- 'AgentJayZ' vid.. he shows this type of blade in detail. youtube.com/watch?v=7upnkrhqRW­Q&feature=g-all-u&context=G283­d500FAAAAAAAAAAA

  • @lexichronicle2 youtube this

    Air-Cooled Blades - Turbine Engines: A Closer Look

  • @doktorbimmer Thanks for the link, that guys got a neat setup going on!

    If you look really carefully at 3.10 when the actual CAD model is flipped up to the root, it does look like there's a channel running up through the blade, as opposed to just microholes.

  • @lexichronicle2 Ah.. they are showing two different types of turbine blades, the first one in the animated clip shows a conductive cooling only type (no small bleed holes) often used for 2nd stage and the CAD clip shows a 'thin film' or 'barrier' cooling type blade. The base is hollow and the main passages extend up inside to the tip with small bleed holes drilled into them from the side. The large passages are cast into the blade, some manufactures use a laser to drill the smaller bleed holes.

  • What are those moulds made from?

  • @210482fmj It appears to be similar to what other manufactures use, a ceramic slurry (clay) coated with sand made using the lost wax process

  • Comment removed

  • And what would happen if that turbine were jammed juring take-off...

  • Duurby?

  • "the size of your hand"?, can somone please explain this!!!

  • @subnannitechnologies A turbine blade is of that size.. So thats what they mean by that.

  • Why does the A340 at 1:40 has 2 types of turbines (size)

  • @TheGianni997 It's an engine test bed. The engine that is a different size is the one being tested. In order to be certified, an engine must under go many types of testing. The main testing is flight testing of the engine itself.

  • lol the sr-71 does not have jet engines but ramjets

  • @h232144 Actually the SR-71 engines are a hybrid type both turbojet and ramjet. during normal flight modes the the engine operates as a turbojet, over a predetermined mach number intake air is bypassed around the turbojet section and it fuctions as a ramjet at high speed.

  • @BuickDoc Well, yes and no, yes there was a long line of folks that published papers or produced drawings but... None of them ever worked. If you read your Wikpedia facts carefully... no one built a turbojet that ACTUALLY WORKED until Hans Von Ohain did it. He's the one man that got it right.

  • is dat catia??

  • Germans are cool

  • Comment removed

  • what is the song from the beginning called?

  • Rolls-Royce went completely bankrupt 1971 and britsh government privatized and sold off all RR assets 1980, RR PLC is NOT britsh owned! major share holders include AXA S.A (France) BlackRock (USA) and Investco (USA)

  • whats the price of a single blade?

  • great engine.... i love it

  • @doktorbimmer Do not blame the ''brits'' for thinking, this, that and the other.

    I think YOU and many other people (or should i say americans?) get confused at this stage.

    Rolls Royce are divided into two seperate companys.

    --RR Motors is BMW german Owned, although RR cars are still built in the uk.

    --RR Aerospace PLC (notice that key ''PLC'' part) however is a seperate company altogether who make aircraft engines and has nothing to do with BMW. and i am a german motor Journalist.

  • Comment removed

  • @doktorbimmer When i mentioned RR Motors i was mearly stating that it is the only german owned part! I was however saying that RR PLC isnt german. when you said in your own words ''it is no longer britsh owned''

  • Comment removed

  • Watching this video I can see why those Trent AIRBUST engines keep blowing up midair, for the type of tolerances that are supposed to be observed and specific quality of materials are compromised from the minute they enter that factory floor. Youll never see a Rolls engine in an Airforce jet PRATT & WHITNEY knows how to build an engine, the only time human hands should be involved is the final assembly that would reduce these deadly accidents that and stupid pilots

  • Derby is pronounced darby!

  • @eyechubcunt Britishit is pronounced britishit.

  • 1. The crout engine only lasted for a few hours

    2. there are still orgional working whittle engines running today

    3. Radial flow was the only practical configuration for the times material technology.

    and people are talking like axial and radial are compeletely different engines; there not! only difference is the method of compression!

    AND whitlle patanted the jet engine long before Von Ohain started work on it. Whittle was developing it as early as 1926

  • @Riechode 1. Its spelled Kraut and its a slur, German jets were already flying for hours while whittle engine could barely run 20 mins in testing.

    2. Yes, you can still find working whittle engines in air museums.

    3. The first working and flying jet engines were Axial flow. The radial design differs considerably and is heavy, bulky and less efficient. whittles early work was based on Griffeths gas turbine, his first designs were not viable and were never built, disregarded by the RAF.

  • Comment removed

  • Leave it to the Germans to I N V E R T the technology.

  • It was actually a german scientist that inverted the turbojet

  • @keirfree Wrong! That is total myth.. In a statement made by Frank Whittle himself after the war he said that Von Ohian's engine was developed totally independent of his own work. Clearly anyone that has actually looked at the two engines would see they are completely different. In fact much of Whittles work was based on Grifiths gas turbine designs that he had access to at the RAF.

  • @Shankovich NO, Its True. The first actually working turbojet engine was built by Hans Von Ohain. Whittles 1930 patent was only a "conceptual drawing" based on Griffiths centrifugal gas turbine. Although it created considerable interest at RAF all agreed it would never power an aircraft. Whittle would not have a successful design prototype or test flight until after Von Ohain, the German Axial type engine was the first successfully tested and first to fly, its the only turbojet still used today

  • @aspiringdrummer17 Wrong, wrong and wrong. Von Ohains axial turbojet first prototype in 1934 first flight test in Aug,1939. Whittle's first full power bench test wasn't until Sept 39', first flight test May 1941. Whittles work wasn't published in Germany until 1940. Whittle was not the first to come with the idea either, Guillaume patents a turbine engine concept 1921 and Griffiths publishes paper on aircraft gas turbine 1926, his papers are made available to Whittle at RAF in 1928.

  • @aspiringdrummer17 There is no need for you to try to discredit VonOhain.. you can't, Its still a very popular myth (mostly among the brits) that Whittle invented the turbojet. But the facts are clear, VonOhain started building prototypes 3 yrs before Whittle in 1934! and Germans flew the first jet aircraft in 1939 a year before too! Whittle's reverse flow centrifugal compressor was absolete the first day it flew. RR and all other modern turbojet manufacturers use the German axial flow design

  • @mudslideVT033 That is a very common misconception that dates back to the war, even Whittle himself thought the Germans had copied his work but if you actually look at the two designs they bare absolutely no resemblance to each other. The compressor, turbine, combustor and ancillary system all completely different on the Von Ohain design and as history proves out the correct combination where as Whittle had headed off in the wrong direction his design now being obsolete.

  • @jeanlucncoelho Actually germany never inverted the jet engine...they invented it.

  • @jeanlucncoelho

    The German was Hans von Ohain

    but the allies credited Frank Whittle who was British !

    But i'd say doth were pretty awesome !

  • Comment removed

  • @doktorbimmer

    True Whittle's thing was a pure jet engine it'd flame out at lower airspeeds... Von Ohain was very practical but like i said .. as they lost the war... they didn't get credits !

  • @ARKIEX Yeah, but the war ended 66 years ago, its time to put the politcs aside and set the historic record straight once and for all, Von Ohain invented the turbojet.. even Frank Whittle knew that.

  • @doktorbimmer

    all we can do is spread awareness !

  • @mrbinary1001 Not really. The gas turbine was already invented and in use! Whittle copied Griffiths gas turbine and used it as the basis for a turbojet, the centrifugal compressor is not efficient for thrust only propulsion and the reverse flow combustors were simply wrong. a bit like trying to use an outboard boat motor to power an automobile. Anyone in jet aviation (except the brits) knows Von Ohain is the man who invented the turbojet, its the German design we still use today not Whittles.

  • working in rolls royce is interesting enough, I build piston combustion engines however, and I can say, there is as far as I know, no part in our engines that are THIS advanced:P but again, piston engines work under less extreme circumstances, but they too are a very important part of the worlds transportation of goods and people:) not that this got anything to do with the video anyway, whats up with all the hate posts anyway?

  • the engineering here is so extreme, I doubt any Islamic countries would be able to ever field technologies like this on their own.

  • hell yeah...rolls royce engines are massive

    all you idiots making this a national thing need to drown yourselves in a remote, long forgotten outhouse somewhere...chances are most of you have nothing to do with the manufacturing of any engine anyway...these guys have gotten you and your loved ones from place to place for years whether or not you know or care...

  • @TheARMAProductions Hugging trees is stupid, plant them and then eat thier fruits, now thats the way to do it!

  • you can see that to produce engines like this with a a smaller team would take much much longer. i reckon some of the factories in china and japan could build some pretty good jet engines also as they make pretty much everything. it would be good to what the japanese could come up with

  • what is the name of the porgram they us to draw????

  • @Mavleop It's one of these three: PTC Pro/Engineer, Siemens NX or 3DS CATIA. I (want to) believe they're using Siemens NX, since it's, IMO, the best mechanical engineering 3D CAD software available to date! ;) BTW, any of the software mentioned above cost like a jet engine. Hehe, nah I'm only kidding... But seriously, each on of them cost tens of thousands of dollars -- expensive stuff! :)

  • @aryesegal1988 wawww thankss metee!!!!!!!!!!

  • Rolls Royce plc is definitely a great company with some great engines and other products. However, there is one thing that I dislike about them. They choose efficiency over safety. They typically use a three spool/shaft high bypass engine, as compared to a GE or PW two spool/shaft high bypass engine. While the RR engine is typically quieter and more efficient, it is also less safe than its GE counterparts.

    The aviation incidents/accidents related to those RR engines are a significant testament

  • If we're going to compare engineering feats shouldn't we throw in 8 trips to the moon?

  • anyone know the first two songs in this video!???

  • big mistake these things were all gonna drown

  • i wonder how do they make airplanes and jets

  • Durby, It's pronounced Darby idiot.

  • funny how we can make the most pufect thing ever made mankind is awasome!

  • "...in DURRBY, England..."

    hahaha

  • Cars should have small turbo jet engines. Just small ones :P

  • well, the inventor of the jet engine was not only frank whittle, but at the same time Hans Joachim Pabst von Ohain invented it in germany. That is why we had the first jet engine powered aircraft. after WW2 he worked for the us air force... but still a good report

  • does he said "DENVER" for business? 

  • @TheAliante

    denver has many jews

  • @IndianMusicVideos oh ok i asked before i didnt understand what the man said

  • hope i'll get hired in rolls-royce new facility in singapore.. im actually under their joint venture company.. but i want to be a direct employee! lol! wish me luck guys!

  • ill respect Rolls Royce when they start making affordable electric cars. till then, go fuck yourself Rolls Royce.

  • @XmojotronX

    Fuckwit !! Rolls Royce, stopped making Cars, decades ago,

    wat planet/ trailer park do you live in ?

  • @keirfree actaully rolls royce still make cars, it just that they're owned by BMW.

  • @only19r Wrong!! Rolls Royce Motor Co makes cars , Not Rolls Royce Engines they make Jet Engines

  • MAS :D

  • this is Rolls Royce one of the most manufacturing company in the world. the other one is General Electric. I like it

  • They made the same mistake in the How It's Made episode of turbine blades that they did in the episode. The thrust made by the engines they are referring to in this are Turbofan engines. The majority of the thrust in most is not made by the turbine exhaust but by the Fan section of the engine. The thrust ratio (called Bypass Ratio) varies from turbofan to turbofan and a turbojet engine having no bypass.

  • @pdlip1

    The Rolls Royce Trent 1000 for the 787 which is shown at the end of this video has a Bypass ratio of 11:1.

  • My Favorite Jet engine is Rolls Royce Trent 800.

  • this video is great, i´m currently studying this and all that was said was pretty accurate

  • dead the end of planet earth evil why cant they use f-cell technology now

  • @bobodd5 heavy, bulky and inefficient, also a HICE system (same fuel as your precious fuel cell and ssame exhaust but instead of driving an electric motor it operates like a conventional jet or car engine) is more effective

  • With all my respect, but the jet engine was invented by an engineer called Henri Coanda and he flew the first time in 1910 somewhere near Bucharest, Romania. It's the same engineer who discovered the Coanda effect.

    Best Regards

  • great tv show " how do they do it" !! I watch it on Sky tv in italy!!!!! thanks for sharing!!!

  • I wonder how long it takes to make one jet engine.

  • @05u16hep your just a dick

  • @05u16hep dont for get that it was your Goverment that did not want it, so he had to go to Germany to get it done. America made the first maned flight. What did you do.

  • @bumbleyou What did we do?? Invent the jet engine, invent the fully flying tailplane and did loads of supersonic research that the yanks nicked, make the first aircraft to have "autoland" basically invented ILS, invented RADAR was first to introduce wide chord fan blades made the first atlantic crossing made the first jet airliner made the first aircraft to have EEC co-made the worlds only SUCESSFULL supersonic airliner (TU-144 was a faliure and coppy)... want me to name any more, co I can

  • I go to skills canada every year and have an engineering scholarship. Building Lego machines has gotten me further than making senseless comments on YouTube, which is where you have decided to stay.

  • LOOKS LIKE A COOL JOB!!

  • That's right!!

  • Here's one thing that i never see explained, a car engine has an electric starter to get it going. What part of a turbojet actually starts it spinning?

  • @cpu64 The APU.

  • will I work in such technicall industry ?

  • rolls royce today is actually nothing but a sorry sight folks

    ı mean in terms of designing and developing military engine

    The last engine for fighter aircraft which RR developed on his own was PEGASUS for HARRIER in 1960's !!!! After that everythin was joint venture..Look at the achievements of mighty PRATT&WHITHEY it eclipsed RR in every single area .RR is still great in engine for commercial airliner but a dwarf in military engines ouıtperformed by its US rivals GE and P%W by 20 years

  • viceroytennis haha RR takes idea from the real masters GERMANS, they build the first turbine jet after sir frank whittle came up with the idea and he is british. Intregrity haha dont make me laugh, also for iamzoli dude come on whittle's engines would be the best if he had the money for it but once more germans build the best aircrafts back at that time when everything started, I'm not german but I have to give it to them.

  • @pred1990 . Don't quite understand what you are getting at here. Sort of a strange English. Sorry. Look up in a dictionary what integrity means, then read a few history books. I can give you a list, if it would help.

  • Very simple my english is probably out of your league, you could talk all you want in the end I'm the A&P tech here. Let me ask you a simple question and if you dont know this plz do your self na favor and dont even answer it, google it do w.e you will not get it correct if you have not seen an A&P textbook. What are the 4 type of turbines out there, the 3 types of turbofans, and what turbines produce thrust and torque? very simple and easy.

  • Turboshaft-tourque, Turbojet-thrust, Turbofan-thrust and Turboprop-tourque

    Turbofan: High bypass, low bypass and geared

    I can name about 5 more if u want me to, so get your head out of your anal cavity and realise you cannot change the past, ever how much you want to. Oh, and what did america invent for aviation?? NOTHING!

  • Ummm...u ever hear of the wright brothers???

  • Are you fucking retarded? Americans were the first to fly. Typical foreign twat mad at the US for spit roasting there country with allies

  • @freezinteen I'm talking about inventions. The wright brothers did not invent the airplane, they simply managed to make one that could actually work. There had been gliders flying for over 1 minute befrore the wright brothers.

    Dont also forget who made the first jet powered airliner! and, if Von Ohain's engine was superior, where was germany's jet airliner?

    It makes me sick to hear americans slagging off the british, and supporting the NAZI's! go play with your LEGO you dirty facist

  • @05u16hep Actually. The Wright Brothers simply flew the first powered flight in front of an audience with photographers! Karl-Jatho was actually the first to acheive powered flight. In Germany.

    Yet again the Americans rewriting history. This is just because the Wright Brothers were rich.

    The Wright's used a catapult for take-off and an updraft, flying down a slope. karl-Jatho flew 4 months before the Wright's without a catapult, tacking off from level ground! -without an updraft!

    Ptch.

  • @05u16hep i believe americans are the founders General electric aviations..?

  • I agree with pred1990 100% ..Hans vpn Ohains concept was far superior..Both men met in 1978 for the first time and Whittle had to admit defeat. Von Ohain is the real father of the jet engine

  • Really!

    If this is the way things will go. What will they do when CMA energy is finally here?

    Picture in your mind an energy drive by a constant magnetic acceleration energy.

    There will be no heating to get any thrust. And will probably be able to develop thrust by the use of a high generation of ions. Think these guys are going to realise the hard way. They are using horse and buggy days technology.

  • dont forget america stole the idea of a movable tailplane to break the sound barrier from british engineers and scientists. but... we english did better and did it commercially with the concorde, which may i add stayed in service for 30 odd years...

  • CONCORDE IS ONLY 50% BRITISH...

  • Only!??

    i think not...

    The whole thing was designed by Brit engineers... We just told the French where to bolt the bits!

  • @Tommiclio well said m8 :D

  • death smelly evil global warmin shite dynojet kitt

  • Rolls Royce is a great company because it has engineering integrity. A little bit more integrity and respect everywhere would make the world a far better place.

    Integrity = adherence to moral principles, honesty.

  • @viceroytennis they are a great company but at the moment are experiencing some problems surrounding the engines used in the Airbus A380's.

  • @viceroytennis Roll Royce and integrity? You must be delusional to mention these two words in a single sentence. However I agree that integrity is a problem today, especially in English and western cultures.

  • you really got to quit bitching about americans. you got to change the record every now and then

  • @rustman217

    Amen

  • Germany got there asses kicked.. twice rofl

  • This is why I heat Fucking American Media 'cause they wanna create their Own silly putty heroes. Whittle Didn't invented the jet engine, Hans von Ohain designed it and Heinkel put it in a plane.

    Does the fact that the allies won WWII give them the right to re-write history to their advantage and discredit their oponent?

    FUCK YOU AMERICAN MEDIA.

  • To Eloidor:

    I don't know why you are so ignorant. Winning a war DOES give us the right to re-write history in our advantage and discredit you. Have you studied Rome or any other of those great civilizations? After winning, they could write it any way they want.

    Besides, it's not like the Germans and the Japanese didn't write their own history books. What your saying is that your going to walk into a German library and find books about how Germany and Japan was so bad and horrible.

    Idiot

  • "Winning a war DOES give us the right to re-write history in our advantage and discredit you. Have you studied Rome or any other of those great civilizations? After winning, they could write it any way they want."

    You call that being moral? Does having the bigger stick (weapon) mean you can kill? Does might make right? Does a victory parade make you unaccountable for your actions, both during the war, or in writing history?

  • haha just get over it
