Rolls-Royce are renowned for high quality graphics and illustrations, so it would be nice to see an updated version of this video with Advance / UltraFan technology and improved graphics! Oh, and please remember to include the tail cone in the illustration of the exhaust ... incandescence in the region of the low pressure turbine bearing housing is generally regarded as something to be avoided!
*My congratulations to the ROLLS-ROYCE family for the work and development of all the engines that are high technology.*
Yes, thank you Rolls Royce for making an awesome video about how awesome you are!
Thank you Rolls Royce for a great video!
You're welcome 😀
@@Elimarzordan i understand rolls royce
that's. what. we call the true dedication towards. the work.as you did in engineering. hats off for your. dedication. which improves fuel efficiency. in upcoming. engines to decrease. the. level of carbon footprint for the better. future
I just watched the same video by Pratt & Whitney yesterday.
I didn't understand too much but thanx for video 👏👏👏😉😉😉
really informational video seeing Rolls Royce rocking Jet Engines
China is watching 😂
Copy n Paste lol
This is the current engine technology. All countries use this system..
😂😂😂😂
But China failed every time
Oh yeah. No doubt about it
There is no explosion inside a jet engine. The air entering the combustion chambers is heated. There is no pressure increase in the combustion chamber. The air from the compressor section enters the combustion chamber where the volume increases, by adding a lot of heat, the pressure remains constant. This heated air is allowed to escape through the turbine. the turbine robs some of the energy to drive the compressor. the rest of the air expands rapidly though the jet pipe and you have thrust. I refer to a book written by Rolls Royce, "The Jet Engine" A very good read.
+Sultan Singh the pressure remains constant after the compressor (throughout the heating process).
+Sultan Singh The air/fuel mix is ignited by a spark igniter when the engine is starting and then the combustion sustains itself, like a stovetop burner. When the mix is ignited, this accelerates the air back... through the turbines before being ejected through a jet pipe.
the pressure remains constant in the combustor, and it's the spare pressure which turnes the turbines
How much fuel is needed for 1hour flight?
100 liters max

There would be some drop of 6-7%
And to this day, nothing beats the sound of a trimmed out RR Merlin mounted to a Spitfire or a P-51 Mustang on a high speed pass.
Great choice of music, I'm a musician. I love the key change at 1:28.
Great explanation
Good job
I like this films.
high learning yield high result it is awesome . I wish ....
I am a long time share holder of RR, They have very innovative design and proven technology. Their piston engine division MTU power some of the biggest ships and fastest battle cruisers. MTU also powers high speed ferries using waterjets.
Of u are there Shareholder then u must be in Profit.😏😏
Tank for the video 🌄🏞🌍🎆🌌
Its real hard work
I swear if they showed this at school I would have became an engineer.
Our great friends
The more systematic use and utilization of electricity and the improvement of equipment and software that allow calculation of ascents and descents with lower fuel consumption, taking into account airflow (stern wind, bow), optimizing B.P.R. The turbofan has to systematically enter the digital area, redirecting the flow of energy produced for greater efficiency, logically in order to reduce consumption. Powerful hardwares, equipped with software would be bringing efficiency data to the cabin. I would propose some corrections that would certainly bring significant results.
Maybe, Mr. Castro! What mechanisms have you proposed for temperature regulation?
superb ..
Yes Yes Vientos Power Simplemente Toda Una Extraordinaria Ingeniería 👍 De Rolls Royce 👉👍💯
can use a part of this clip for educational purpose in my own language. maybe 10 seconds.
Excellent bro excellent
Generally all gas turbines depend in their work on drawing air from the outside and then increasing its pressure and speed with condensers to tens of atmospheric pressure depending on the number of disc blades so that the friction between the compressed air particles increases with each other inside the condensers, which raises the temperature of the compressed air to many times the boiling point of water to accelerate the combustion of the fuel spray coming out of the syringes in the combustion chamber, which increases the efficiency and concentration of the directed kinetic energy resulting from the combustion, so that the combustion product acts as a feedback by moving the exhaust blade discs connected to the same axis of the compressor discs to control the work of the turbine, but if the concentrated air pressure inside the condensers is disturbed, the energy of the resultant in the combustion chamber will be dispersed in all directions and may cause an explosion inside the gas turbine, so the margin of error during manufacture of the turbine disc blades does not exceed several microns to ensure the stability of the flow of the compressed air inside the condenser.
thanx a lot 4 da video ROYCE
Awesome
Thank you
C,est mécanique moderne sont des merveilles
Ohh i see. Thanks alot rolls royce!
What's the break down of the total thrust from:
air flow as 'pure thrust'
air ignited 'generating more thrust'?
You generate most thrust from none combustion?
Interesting video. Thanks for posting it. Nevertheless, after all the troubles with the Trent 1000 engines in recent years it seems to me Rolls-Royce's repute as "one of the world's leading engineering companies" unfortunately is somewhat at stake. I have no doubts Rolls-Royce once deserved the title "best company in the world" on making engines, but that was back in the days of pistons and fantastic engines such as the Merlin, which I think we all should still be very thankful to Rolls-Royce for. I hope you'll succeed in fixing the problems with your current engines, so that your excellent aim for creating better power for a changing world can be achieved. Best of luck!
per me ormai sono motori superati vecchi basati su principi fisici parziali,io ho indubbiamente ciò che manca con una evoluzione senza fine
muito bom show de vide-o
I like it Rolls-Royce
Muito Interessante
How do the turbine blades endure this much high temperature for a long time is there any cooling system being employed ?
Am on The roll with The Rolls

More and More Ahead
With my beating heart... a Rolls Royce engine.
wow.
nice sir ,
Hot gas comming out of the tail bearing housing instead of the low pressure turbine - odd.
It's not odd, it's normal, the hot gas gets directed to the Tail Bearing Housing Nozzles, and where the LPT actually is they put the cone to direct airflow back in the center and mix cold and hot gasses on the exterior of the engines
@@Jeremy974 more confusion.
bravo, you saw their fail, it is wrong how is animated, hot gas goes through turbine , not through bearing housing
Great
Britian amerca this people are very clever and all ways the top
german
They should really pump out more Merlins
My uncle used to work for ur aircaft engine division
Nice
i'm in love
Luarbiasa kak
talk about how china got version of the Spey 202 (the WS9)
Best 👍👍👍

Wonder how fast the fans of the Rolls Royce Olympus would've been spinning...
Please what is the appropriate role to run?
Is the animation wrong? It shows the exhaust in the center instead of annular out of the outer ring🤨 I’m I wrong???
Thomas Schwenke explains this way better. Can I have an engine?
Competition,qualityand security of motors by Rolls Royce .
The motors of Rolls Royce,the go well the time perfection .
The jet exhaust exits the annular ring around where it is shown to exit in the center . 🤨 how manny people caught it🤷♂️
Super
以前、トライスターにRB211ターボファンが付けられていましたね。

Rolls royce perfect
0:32 suck, squeeze, bang, blow
hmmmmm lolll
We respect US,German , Japanese , French,Italian and other countries engineering..but nothing, Nothing can be better than RR aviation engines. Million out of million engines,never failed. RR aviation, it is a very solid company. Do not make confusion with BMW RR cars.
Finally, a plane engine lore
Video as per title starts from 0:30
Superbe 😍😍😍😍
BEST TECHNOLOGY ROLLS-ROYCE.
0:57 The animation is wrong. The exhaust doesn't exist in the middle as a solid stream but rather from through the annular section at the rear.
As you can see at 1:04 there is a metal cone were the exhaust is previously shown to exit, and the annular exhaust nozzle is seen around it.
It comes out in a annular ring right? I just posted the same thing and read down to you! So I’m not crazy !!!!!
Good eyes you would be great in racing!!!
They dont give right info so no competition lol
0:58 A video from Rolls-Royce and they still can't show the proper hot exhaust gas path.
I wanna say this 🙈
What they left out is that the fan blows air through an ever narrowing bypass duct, this air compresses as it’s forced to squeeze through the ever narrowing duct. Once it gets to the back, it flows around the outside of the combustion chamber and cool it, the bypass heats up and expands, shooting out the back of the bypass nozzle providing jet thrust. That’s how bypass air produces thrust!
Magnets are attractions that have magnetic fields. There are 3 ways to make magnets, namely by rubbing, conducting electricity, and magnetic induction. The use of magnets in specially crafted work that is made using electric current, is widely used in various tools including compasses, electric motors, telephones, and telegraphs.
Porque estoy seguro que roll Roy's engine will get in space ⚡
wow
Skipped a few steps there on the turbofan and the exit flame is downright in the wrong place if I understand correctly.
I find it's always better to explain how it actually works instead of attempting a simpler incorrect version.
Loved it amazing minds respected 🇦🇫

U can replace KEROSENE FUELL with hidrogen or oxigen or mix 2
GE90 and Trent-700, Trent-XWB using of gasoline
Beautifull. Batteries and evs, hold thy beer.
What's interesting, in today's Turbofans, the majority of the thrust comes from the Fan!

yes that is write according to what i have watched in previous videos
What about the Olympus
Jet engines scoop air in at speed so, in theory, if you designed the inlet as a rapidly tapering nozzle, you could make it compress the incoming air automatically, without either a compressor or a turbine to power it. Engines that work this way are called ramjets, and since they need the air to be traveling fast, are really suitable only for supersonic and hypersonic (faster-than-sound) planes. Air moving faster than sound as it enters the engine is compressed and slowed down dramatically, to subsonic speeds, mixed with fuel, and ignited by a device called a flame holder, producing a rocket-like exhaust similar to that made by a classic turbojet. Ramjets tend to be used on rocket and missile engines but since they "breathe" air, they cannot be used in space. Scramjets are similar, except that the supersonic air doesn't slow down anything like as much as it speeds through the engine. By remaining supersonic, the air exits at much higher speed, allowing the plane to go considerably faster than one powered by a ramjet (theoretically, up to Mach 15, or 15 times the speed of sound-in the "high hypersonic" region).
Hi Royce, could you just give the engine to turkey please ? Just so we can build our own fighter jet as soon as possible thanks
now i understand why the renewable energy is not welcome
Why some of the blades are turning in opposite direction?
Counter balance and efficiency.
What stops the hot air expanding forwards?
CommanderLake pressure and direction of flow

Giant passenger jets have huge fans mounted on the front, which work like super-efficient propellers. The fans work in two ways. They slightly increase the air that flows through the center (core) of the engine, producing more thrust with the same fuel (which makes them more efficient). They also blow some of their air around the outside of the main engine, "bypassing" the core completely and producing a backdraft of air like a propeller. In other words, a turbofan produces thrust partly like a turbojet and partly like a turboprop. Low-bypass turbofans send virtually all their air through the core, while high-bypass ones send more air around it. Impressive power and efficiency make turbofans the engines of choice on everything from passenger jets (typically using high-bypass) to jet fighters (low-bypass). The bypass design also cools a jet engine and makes it quieter.
The secret is the narrowing of the air-stream inside the compressor. The compressed air builds to a pressure that is actually higher than that of the fuel/air combustion - but - it has a much smaller cross-sectional area. As the fuel and air combust and move rearward, the passage widens again, but still at a lower pressure than the compressed air-supply (meaning it can never reverse flow). The outlet gases of the engine do more work than the compressor because they have a much larger surface area, so with gearing, the drive turbines are able to compress the air and still have energy left over to propel the aircraft.
You have just hit the nail on the head there, sir !! This is NEVER explained but I will now try to explain (but it's only my version that may not be totally correct).
Any fan / compressor has what's called a `fan curve' (also pumps have pump curves) to illustrate how it will perform when the flow rate is varied i.e. how the pressure across it will vary as you vary the flow.
Invariably as the flow is decreased the pressure across the compressor INCREASES; therefore during start up of the jet engine when the burner is switched on the pressure after the compressor stage increases which will tend to reduce the air flow into the compressor but this reduction in air flow will increase the pressure gain over the compressor so a new BALANCE is achieved with the burner on. Google `fan curve'.
With the burner on this vastly increases the volumetric flowrate with the pressure reasonably stable.
The same can be said for a locomotive steam engine - with the boiler sitting at e.g. 10 barg (145 psig) and zero steam take off the fire only has to supply boiler heat losses. Once you start to draw steam off the fire has to provide a lot of heat to maintain the steam flow rate at the same pressure.

U can replace KEROSENE FUELL with electric motor to move turbines to compress air to move the Airplane
No you can't! In case of a big RR Trent engine, let's say for a Boeing 787, the fan easily requires 50 MW of driving power to produce full thrust. Just imagine the size and weight of an electrical motor with that power and that doesn't even include the necessary power source.
That’s the most retarded idea I have ever heard
Who else learned more about train engines?
I have a motor design for you that is never been seen before no gas Newfield nearest solar powered look it up ( X JDA 33 ) one of a kind you could say out of this world
+King James USA (JDA.33) This is an induction motor. What person makes a claim about a never before seen motor without looking it up?
Was not talking about this video
King James USA By the way I'm pretty sure one of the most advanced engine companies know of a basic induction motor.
Perfect for india

I love your luxury cars Rolls Royce,,
Wait where does the piston come into play in an aeroplane? You mention how the aeroplane gas engine works but said that a piston engine is also a part of a plane engine?.... I'm guessing you just mean that the piston engine was used to develop the gas engine of a plane right?
Wao
How it rotates
Does it has motor
The turbines at the back of the engine use combusted air speed to generate rotation, which makes the whole syspem spin.
but how do the blades rotate to suck the air inside?
+MV N Do you mean once the engine is started or how do they spin to start the engine? Once started, energy is absorbed from the combusted gases by the turbine blades and used to spin the compressor and fan blades via a shaft to make the process continuous. In order to start (if I'm not mistaken) I believe aircraft carry a small auxiliary power unit which is used to rotate or spool up the engine until it is running under its own power.
yes but why does it suck air in?
