The cabin should be placed on pods on either side of the wing, whilst the engine will be on the middle. Just like those wacky plane Photoshops of the 2000s hahaha
Well it still would because the ultra fan for the narrow bodies will not be 3.5 meters but rather around the 2-2.5 meter mark. The 3.5 meter ultra fan is for the wide bodies like the A350 that is almost 7 meters wide. So its still about half the diameter.
3.5 meters isn't quite as large as the 4m Boeing 737 fuselage. Speaking of the 737, if Boeing is going to keep that plane going they need to make smaller engines for it.
I spent the bulk of my career flying on RR engines. The Dart, RB.211 on the 757, 747 and L-1011, and now the BR 725 on the G650. Best engines in the world as far as I’m concerned. Godspeed RR on this new one.
Yes. My old company had a pair of BAC-111s, but I never flew it. Flew the Fh-227/F-27 with the Darts. We used to joke that the Speys on the BAC-111 were the world’s most efficient way to turn jet fuel into noise haha.
Unless the materials they used are actually that colour, it’s most likely that this colour was chosen for marketing purposes. We don’t even know if operational Ultrafans will retain this colour scheme.
It will not be as powerful as 9X , since it is efficiency focused. so it has to increase the fan size to get more air through to compensate smaller core and less fuel burn while keep the same power output as the current Trend series. It will sell like crazy with that level of efficiency.
@@dctraveler7507 This doesn’t make any sense. Not quite sure where you get that. All engines are efficiency focused. Why do you think they built the GE9X in the first place? Power does not need to be sacrificed for efficiency and vice versa. The increased fan diameter (combined with the sweep of the fanblades) is for higher bypass ratios which allows three things: - lower fan rotation - lower noise levels - combined with optimum compressor rotation speeds allows better fuel economics. *It has nothing to do with the smaller core nor fuel burn.* However. There is a problem. With RR iconic three spool design, in order to achieve such low N1 rotation with the optimum rotation of the IPC and HPC requires a heavy and seemingly specific redesigned LPT. That means added weight and complexity. In order to achieve that goal they removed the LPT and use a gearbox connected from the IP shaft to drive the fan. With it allows lower amount of stages which results in the smaller core but don’t be fooled. Thanks to the gearbox and redesigned fan the Ultrafan has 15:1 bypass- and 70:1 pressure ratio. High pressure ratios such as that allows for lower *TSFC* which stands for *Thrust Specific Fuel Consumption.* Lower TSFC does NOT equal to less power. As for the Ultrafan being less powerful is arguable. I can see that it might be less powerful. But I fail to see as to why it automatically can be presumed to be lesser. Mainly because thrust comes from N1 rotation speed, air density and propulsion efficiency of the fanblades. None of what you said substantiate as to why the ultrafan has lower thrust. However, if I were to spitball here. The only things I can think of that might lower the thrust capabilities of the ultrafan is durability of the gears and core OR aircraft specific thrust rating. The higher lift capabilities of the 777x is the reason why the GE9X-105B1A is rated lower than the GE90-115B. Other than that I see absolutely no reason as to why the Ultrafan has lower thrust than the GE9X.

Even a 1 to 2% improvement in fuel efficiency is pretty significant for the flight industry and air transporters. A 25% improvement is to good to pass.
When GE developed the GE90-115b for the 777-300ER, Rolls Royce offered a Trent engine of the same size and power but Boeing were going with the single choice for that variant and it was never made - it's a shame because most people presume that only GE were capable of creating such a large fan and powerful engine. The superfan has the size - but is not rated so highly and is all about economy. I doubt we will ever need an engine with a thrust of of the 115b again as we are unlikely to see twins larger than the 777 - even the GE9x has less power.
As an exceptionally proud Englishman, I'm very pleased that Rolls Royce are going to take on the epic proportioned GE-9X. We are perfectly capable of designing a more capable engine, after all...we did come up with the RR dual spool axial flow turbo jet Olympus engines which are still mightily impressive now in 2021, even though they were first designed in 1950!!!🇬🇧🇬🇧✌✌
Ge9x now has competition. Will wait for the test results and hopefully the project goes well. With less people traveling it's a good time to invest in this program before the boom.
For those wondering, this engine is roughly 10cm (4inches) larger in diameter than the GE9X It's also larger than the 737 fuselage and a220, which is quite interesting, since they want to use these engines for narrow bodies as well, imagine a plane with engines that's bigger than the fuselage itself
@@arnavsharma9882 they said they wanted to use these to power narrow bodies (in the video) but I agree, bigger engines = more weight to carry around = higher fuel consumption
No, the idea and a good one, is to scale down. Once tested and up and running, the engine could be scaled down for smaller aircraft, giving them, the benefits of the Ultra. Then you would have a platform, to build for any size aircraft without the need for lots of different types of engine-all Ultras but of different sizes.
Does anyone else think that one day having a 15-25% more efficient engine will be impossible because the current engines are as efficient as possible. What will engine manufacturers do then?
I have always had the greatest confidence in the ability of Rolls Royce to design and build World Beating Jet Engines and I look forward to this new development with enthusiasm. Lots of power, good Fuel efficiency. and low emissions and most of all low noise are goals well worth striving for. Brittain no longer has a Passenger Aircraft industry to supply its Engine products to , so we have to built the best and supply Airbus and Boeing and if possible build better Engines than they do in the U.S.A.
Does a comparison with the first Trent engines imply the possibility that RR are looking to offer the airlines a cheaper route to increased efficiency by replacing engines on existing airframes rather than buying brand new aircraft? It might also offer a solution to those problematic engines for which a total fix seems to be elusive.

No, the idea and a good one, is to start large, then scale down. Keeping the improvements but with smaller ultras to suit the aircraft. I would not recommend any for the 737max.
I say it again. 2 inlet fans for 1 outlet is what is required. These modern engines are getting silly large. Soon they will have wings attached each side of the engine and somebody will say, "er, what about passengers?"
I wonder why they had to make it so big? Surely smaller engines would be more profitable as they can be replacement units for a vast fleet of existing airplanes already in operation. This monster will be available only for very large airplanes, and in a post Covid-19 world with much more limited air travel needs and volumes, I don't think this monster is appearing at the right time. Smaller engine please.
If only we can retrofit newer turbofan engines to older airframes/airplanes. That would increase aviation efficiency in less time than waiting for new airplane models/variants to be manufactured. But airplanes aren’t modular so they can’t be future-proofed for upgrades.
@Joe Davison "Will they be powerful enough to fly the 747 or A380 with only two engines ?" My guess that an even larger version of 777 than 777X will use them. Emirates, Qatar, Etihad, and Singapore would be interested.
How would this monster fit on a practical plane ? Its got to be part of the wing structure itself, unless the plane would be even more massive than the 380.
25% is a huge reduction! as we know fuel is the largest cost to an airline, this could allow for lower tickets once the current fleet is retrofitted or replaced. i for one am exited to see it on the 777 and many others!
Even a much smaller reduction is more worthwhile than it seems. The plane has to carry the extra fuel which takes more fuel to carry it. One wonders if the 25% is factoring in the lesser fuel load to be carried or if this is the bare figure per hour. Which would indicate even greater savings in operation. Time will tell.
These look cool. Love seeing the technology in jet engines keep improving. GE90s were a great breakthrough and we will see if these are the next evolution. Funny covid was brought up like that has anything to do with this lol.

No, the idea and a good one, is to start large, then scale down. Keeping the improvements but with smaller ultras to suit the aircraft. I would not recommend any for the 737max.
Great to see plus 25% less fuel further flight time plus better for the environment
This is a story about big fan blades, but there are no details about them. Aircraft engine nerds will be disappointed.
Forward thinking always has an added investment for tomorrow's aviation, But always worth the time, effort and cost. Proceed !!!
I say it again. 2 inlet fans for 1 outlet is what is required. These modern engines are getting silly large.
Soon they will have wings attached each side of the engine and somebody will say, "er, what about passengers?"
The engine sounds like a winner but Brit management + Brit worker unions are well known for snatching success from the jaws of Victory.
Snatching success from the jaws of victory? This is why we read things through :)
Only time will tell it's efficiency.
Narrow body? The engine will be larger than the plane! Which narrow body are they thinking of?
Possibly the A380?!? 🤣
I wonder why they had to make it so big? Surely smaller engines would be more profitable as they can be replacement units for a vast fleet of existing airplanes already in operation. This monster will be available only for very large airplanes, and in a post Covid-19 world with much more limited air travel needs and volumes, I don't think this monster is appearing at the right time. Smaller engine please.
Brilliant Company 🇬🇧
It looks like a geared turbofan. Is it ? Makes sense.
If only we can retrofit newer turbofan engines to older airframes/airplanes. That would increase aviation efficiency in less time than waiting for new airplane models/variants to be manufactured. But airplanes aren’t modular so they can’t be future-proofed for upgrades.
Will they be powerful enough to fly the 747 or A380 with only two engines ?
@Joe Davison "Will they be powerful enough to fly the 747 or A380 with only two engines ?" My guess that an even larger version of 777 than 777X will use them. Emirates, Qatar, Etihad, and Singapore would be interested.
Any idea on the thrust ratings of this engine
Just wondering how much larger than the 777X or the A350 engine is. It should require lengthening of the landing gear to ensure ground clearance.
At this rate, the 737 could be turned into an engine!
Maybe with 3 of these we will see 747 a380 size aircraft being built
Another benefit besides noise and fuel efficiency might be it can swallow a bird with less damage.
Ultra ultra high bypass turbofan
How would this monster fit on a practical plane ?
Its got to be part of the wing structure itself, unless the plane would be even more massive than the 380.
bigger than the GE90
It's on hold for now.
This is technology that will be redundant very soon.
Maybe just one massive central engine and mount two smaller passenger pods on the wings?
Hope they've got a strong elastic band.
I am a nutter, I think jets sound nice. No doubt these will sound even nicer especially when you take to the air and they are just humming!
What is the ratio of these UltraFans?
When the landing gears do not function, you can use the engines as skis.
No longer will need to worry about bird strikes... This thing is going to eat other planes
25% is a huge reduction! as we know fuel is the largest cost to an airline, this could allow for lower tickets once the current fleet is retrofitted or replaced. i for one am exited to see it on the 777 and many others!
Even a much smaller reduction is more worthwhile than it seems. The plane has to carry the extra fuel which takes more fuel to carry it. One wonders if the 25% is factoring in the lesser fuel load to be carried or if this is the bare figure per hour. Which would indicate even greater savings in operation. Time will tell.
Maybe we could see a 747 twin engine? Or it’s definitely an end of an era?
It may have enough thrust but the 747's wings aren't strong enough in the right places. Plus the B747 is a near dead product.
These look cool. Love seeing the technology in jet engines keep improving. GE90s were a great breakthrough and we will see if these are the next evolution. Funny covid was brought up like that has anything to do with this lol.
Certainly combined with a new wing shape like Blended Wing shape it could be a real game changer for efficiency.
Turbo jets have no external moving part putting the fan behind bars with a moving scrapper to keep it clean
Narrow bodies too eh? I’d love to see a couple of these bolted to an A220
one would be too much! lol
Or E195
Lol it would be a mini concorde😂
Not possible
They will scale the technology up or down, and produce smaller engines for narrow bodies. The improvement itself is essentially the geared turbofan.
