I was a student at GE Engine school in 1987. This technology was already explored and their engines, the Unducted Fan engines were already in their in house museum in Evendale Ohio. Commercially unviable because of the inherent noise.
Indeed, I saw the NASA GE Boeing 727 inducted fan fly in the 80’s or should I say more than saw it we heard it. Extremely loud and we heard it long before it flew by
They're making a comeback because they mitigated the noise problem.
@@jtjames79 Good Luck. Only time will tell the story.
😅
If that mess is the only choice, I'm not flying.
Incredible! Thank you for the report.
I worked in aviation, Navy & commercial for 45 years. The changes in everything - engines & airframes is AWESOME. I'm so proud to have been a part of it. To the younger kids out there, get into this field. It's growing faster than any weed in your front yard !
@@aabbcc5154 dones will di ? Have you graduated 3rd grade yet ?
GE has been flogging this since the 80’s
GE is the owner of CFM
You started with one subject and without completing it you took us into another subject.. 😅😂
I notice that too.
Excellent vids.
I spent 20yrs. working in aviation and have since retired. I miss being a part of the processes shown in this video. Its a different way of life, you have to perform at a higher level than your everyday Joe. Anyway, I least I can say I've done that. Shout out to my fellow A&P's....IYKYK.
I’m just starting. Long way to go
Yea me too
I retired from Useless airways as a A&P and FE after 21 years in 2001 after the Arabic flying club changed aviation.Went into healthcare as a RN, never looked back... the Airline Company and passengers became more savage in action and deed every year.
Merci, en verifiant CFM je vient seulement d'apprendre ce que veux dire CFM ( moteur CF56 de GE + M56 de snecma = CFM) d'ailleurs aujourd'hui meme si SNECMA est devenu SAFRAN ça reste comme çà car ce sont des contractions de noms de produits. GE and SAFRAN seems to be 50/50 wich is fun to see franco-US motorists in aircraft competition. I am far from being a specialist is the RR ultrafan just larger than LEAPs ? Or is it technologically totaly"new" ?? ( I just understood larger) thx Of course because i am french i réd than CFM rise was design by SAFRAN in 2008 so it's french idea ?? Or not ? Thanks
I don't think its about dethroning anyone, its about many things, weather robustness, reliability, economy and other factors only Airlines need to think about, never the less good film.
Regarding past attempts at this that had experienced too much noise/vibrations … were they using winglet type blade tips which both improve efficiency and greatly reduce the noise inducing tip vortex?
Excellent video commentary!
The city in the UK where the RR Trent XWB engines are made, is Derby. It's pronounced *_DAR-bee._*
Ar rite m' duk 😅
Tomatoes or tomatoes?
You can't teach AI how to speak the Kings English
They have been working on the unducted fan engine for a long time. However this is one of the reasons why Boeing said that they would not be putting out a completely new design for a few years. Plus the wing designs are all over the place witch means a lot of expensive experiments to find speed and fuel efficiency.
I thought the factory was in Derby ?? But what do I know ... I'm Welsh 😂😂
Pronunciation correct at least😂
Would be interesting how much share the other manufacturers have. There are definitely more than PW, GE, RR and CFM. Despite in the video they amount 100%.
As a life long Machinist this is sexy cool
What would be the sound noise level?
Totally unlivable.
Like TU-95 😂 new old technology
The noise is going to be horendus
@@vladimirassalukas6726 Everything old is new again.
@@vladimirassalukas6726 Exactly my thoughts😃
You say the second set of blades are fixed yet the footage definitely shows them rotating.
That is another engine. Keep in mind, no CFM RISE have been built yet currently.
I took from that ,was that the second set are fixed " pitch," not rotation.
illustrated @1:08
Most of this video is on the XWB not the Safran engine. 2min on the RISE engine rest on XWB. misleading title.
Probably because it's the best engine in service on the planet.
Nice, How about Exptotic Alloys and Metals, and the machines that require them.Their cost and the expertise neccessary in their creation, also history of their discovery. May need multiple vids. Enjoying your vids, try to keep em short. I can never get enough interesting info.
My late Dad was an Engineer on the CF6 in Evandale and it is wonderful to read these accolades. Thank you. Does anyone remember Myron (Mike) Petersen?
Are they quieter are they going to propel the aircraft or pull the aircraft?
Imagine a wait list on order. Specially on RR
UNBELIEVABLE!!! WOW
yes
No mention of the GTF Pratt makes? Over 20% fuel reduction and over 70% noise reduction and already in use now.
At the cost of repeated engine failures, the villain behind the failure of the Indian Career GO First (formerly GoAir). Even IndiGo is facing the same shit! CFM LEAP on the other hand, is a down-scaled GE-90, sharing the same qualities of this successful engine, with a few improvisations.
@@JishyFishy4106 the GTF is not having “engine failures” their issue is a manufacturing process problem with materials. The engines are out of service for inspection related to that. I get it either way they’re out of service. However the engineering design is producing better results then anticipated and the leap, Also since it’s improvements are done without increasing the core temps like the leap it has a higher ceiling for even better improvements.
We used to operate Boeing 747's with both the RR RB211 as well as the GE CF6. Hands down, the CF6 was quicker to start and far less complicated than the RR counterpart. We also had CF6 engines on our 767's which were nothing but fantastic- reliable and efficient in every way.
The RR is a three spool,the CF6 is a simpler two spool.
But the RB211 was more efficient with its 3 shaft design.
Maybe im a bit old, but to me Rolls-Royce will always stay as the hand build top of the line and best you can afford in the world. When I am boarding a craft and look at the RR on the engine, I get a felling of top safeness.
There’s a reason you see tons of CF6’s all over the world. Great motors
@@eugeneoreilly9356and?
I would like to see an A350 neo with the ultrafan.
No they don't do an explosive confinement test during the manuafacture process. They do it during the design process. 🤣"It can't be delivered just yet" If you do those destructive tests it will never get delivered lol.
The fan duct, beside directing the airflow, protects the plane from blade separation and puncture of the cabin. These new engines will have no such protection.
Propellers were on planes for a long time though.
@@tomsherwood4650 Propellers aren't this flimsy, even so, propellers have separated and brought the plane down numerous times.
Quite right. P.R.
If it’s made of carbon fibre then it shouldn’t be a problem. Adding extra reinforced walls on the fuselage where there can be a hit should be enough.
@@elmersbalm5219 Hi Elmer. The term "should" isn't good enough for aero engine designers. The energy in a separated blade can be calculated exactly for any given engine speed, and the thickness of duralium needed to stop penetration also calculated. We no longer "fly by the seat of our pants". Even a partial penetration can result in an explosive decompression that can spread beyond the reinforced area. This is why having the engines buried in the wing roots (D.H. Comet, Tu 104) was phased out, and engines on pods under the wing well away from the fuselage favoured. If one Comet engine shed a blade, it had between 30%-50% chance of rupturing the fuselage, the same event in a 707, with the two engines closer to the fuselage (2 & 3), only had a 10% chance of causing a fuselage rupture. The outer engines (1 & 4) had about a 3% chance, based on dividing up the circle of where the blade might go. As engine reliability improved with advances in high temperature metallurgy, aircraft with engines close to, and even inside the fuselage became possible. (727, DC !0, VC 10, Lockheed L1011). It's all about the mathematics of engineering, and I'm sure you'll agree, "there's safety in numbers". All the best, Cheers, P.R.
U know government is too big when you have the people with the expertise having to get approval from bureaucrats with little to no knowledge of innovation
Commercial aircraft regulation is great! You are alive because of it
Hi. And you know government is too small when a plane falls out of the sky and all others of that model aren't immediately compelled to cease flying. "People with expertise" in the small picture can be totally out of touch in the bigger picture where we all live. Cheers, P.R.
So pleased that they all need propellors!
I thought I knew everything..but I didnt realise RR engines contained a Turban - nice to see diversity in action.
i had safran at my school yesterday we had the chance to see this big boi in AR
Awesome.
So aviation started in 1903 with a propellor turned by a small gasoline engine and the future of aviation is a propellor turned by a turbine. Got it.
Interesting how it seems we've gone into a full circle... h m m . . .
Not quite
@@heftosprod Looking back on this, yeah, yo can probably explain it better to some degree. But if I'm right, a propeller powered by a gas engine is a simple propeller, but a propeller powered by a turbine is a type of engine known as a Turboprop, if I'm right... feel free to correct me on this.
@@benjaminpersonsthevoidhermit turboprop engines have existed since just after WW2... Such as the Rolls Royce dart. This is more of a prop fan type I suppose.
@@heftosprodAlright, though we both can't really say for certain what this is until we get more official confirmation, right?
The Rolls-Royce _UltraFan_ is more a technology demonstrator than anything else. The very fact it can be scaled down to a small, 25,000 thrust (111.2 kN) thrust engine means Rolls-Royce is looking at the possibility of a smaller engine that could be fitted to the Airbus A220 or Embraer E195-E2 airliners, essentially offering a second engine choice for these two airliner models. And Rolls-Royce might be thinking of offer the smaller _UltraFan_ engine for even the 737 MAX.
Yeah this technology was already explored yet noise pollution killed it.
And how's the Ultra Fan going now 😉
It’s been 6 months and I’m still waiting for this engine to revolutionise aviation. What happened?
Yea, I bet it goes over like a brick.
This is my highschool science project back in 94...
It's no new idea to use prop-fans. If only they find a solution for the noise they are creating
The noise is the result of the blades going through the air, so it's not likely.
@@ghost307 am aware about that. It's most likely the reason why it has so far not been used more.
When you think of the noise reduction we are currently at now with the A380, B787 and A350 compared to the B747 or B777 this thing would be a step backwards in time like 40 years in time
what about torroidal propellers? can this design be imporved by using torridal bladed propellers?
Se não me engano ja teve um motor desse com pás contra rotativa de um consórcio Brasil Argentina.
The main problem is as a new generation is developed you learn new information throughout the process,where as a whole concept seems to appear from the development process,that in its self births a new dimension what also needs to be developed..round and round we go
Is every engine tested with the water and the freeze type of test, or is that type of testing done during development only?
This was tried on the Beech Starship. Among other issues, the excessive noise from the supersonic prop tips ultimately doomed the concept The Starship was actually responsible for noise restrictions at airfields that previously didn’t have any
Hi L.I.T.D. Quite right. Check out the Mc Donnell Douglas F101 Voodoo that had a supersonic propeller. Just one XF 101 was made because the noise levels made it a noise weapon in its own right without firing a single missile. This video on what should be well known "dead ends" reminds me of the well known proverb "He who doesn't learn the lessons of history is doomed to repeat them". Cheers, P.R.
The big issue with the Starship, and the Piaggio P180 is simply dirty air in front of the props. It doesn't hurt efficiency much, but it's horribly noisy. This is true of pretty much all pusher designs at any scale. Small RC electric pusher wings are almost as noisy as gas engines. Even moreso for the counter-rotating fan engines. The noise comes all from the 2nd set of blades ingesting dirty air. What makes the CFM Rise special is the stators behind theb lades are not rotating which greatly reduces noise.
YEP. This will totally 100 percent fail. Total waste of money. A High school student can tell you this will not work.
@@knottyboy6086 Hi K.B. The interesting question is WHY is this research taking place? The manufacturers must know of past results, and that turbo-props (which is what these engines are) lose efficiency rapidly over 25,000 feet. Jets, flying at 39,000 feet, use half the fuel of the turbo-prop due to thinner air and less drag. The ducted fan-jet also uses the ram-jet principle which is why they can go 2.5 miles higher into the thinner air without losing efficiency. Removing the duct is removing the article that makes turbofans so efficient. I suspect the main driver of this research is an over-generous tax write-off that allows 100% credits for anything spent on research, whether the project is a proven dud or not. That way they keep their valuable R.& D. people in continuous employment, and the company books remain in the black. And who knows, something of interest to the military may come of it. Cheers, P.R.
@@philliprobinson7724 You heard it already in the intro "sustainable" "environment" "CO2". This is where the tax payer money is buried.
Slightly misleading. CFM is jointly owned by the US GE and the French Safran Aircraft Engines in a 50-50 ownership so all engines produced by CFM are joint ventures of these two companies.
You spelled Derby wrong.
Cool looking anyway!😎👍
DERBY....NOT DARBY. BUT IT IS PRONOUNCED LIKE DARBY.
Well, this is an American voice and pronunciation to a European ear is always strange.
@@johnjephcote7636 He pronounced it correctly, but was spelled wrongly in the video text.
I also have a question about this technology,what amount of energy is involved at the by pass part of the engine, i ask because like most I am aware of how much heat is generated by a normal compressor. If the compressor was increased in size a little and made the purposely increase the air tempreture to a much higher rate then surely the bypass gases would contrubute more thrust without increasing the fuel consumption, after all, its what come out the back end that gives each engine its capability. The other part of the question is we are all aware that splitting water into the two seperate gases and then combining the two as a fuel generated a lot more temprature, is there not a way to improve the method of sepetating the two gases to a point where it is enought to run an engine Then the cost would certainly be a lot less plus tberecwould be no polusion what so ever, and as an added bonus the engine would give a completely clean burn taking a lot more care of the engine itself, plus it would mean there would be no flamable fuel at all possibly making planes a lot safer in the event of a forced landing. I am sure that the technology of hydro fuel cells has come a long way it just a question of developing a really efficient fuel cell that is notbtoo heavy.
90 percent of the propulsion comes from the fan on the front.The other 10 is from jet efflux.
They tried this in the 1980's, times were different then, tech has improved, etc. Perhaps this can happen now.
A fools errand. TU 114 was tried in the 50s. Do you understand that there will be no much scientific advancement in the next 100 years! Electric cars were popular in 1900s, no new ideas since 1970s. We peaked bro! Realize that fact
The same thing can be said of stories. You can split it, you change characters names, settings, bend genres, etc, but the core story problem has already been done. No new thinking, just repackaging.@@Pmooli
What amazing pieces of engineering! Incredible!
Sound of silence sucks. Place holder comment.
Counter rotating high speed machete-like blades. I ain't going anywhere near something like that! Nightmares.
How exactly would the first engine give the airframe ANY protection if or when one or more of the blades fail.
It's pronounced Darby but spelled "Derby". And the engine is secured on the pylon by 50,000lb of "thrust"? Not torque? Curious that Rolls is using a gearbox on the UltraFan demonstrator copying Pratt's design. Years ago I read UltraFan would also have a fan pitch change mechanism, but I don't see any mention of it anymore.
It isn’t 50,000 pounds of torque…it’s less than 1000 foot pounds.
@dieselyeti I could never understand why RR went the geared fan route. They already have a 3 spool core so the low pressure, intermediate pressure and high pressure spools all run at their optimum speeds. A 2 spool doesn't have that luxury hence the gearbox.
Interesting , Thank you . I hope they work
*_futuristic alloy_* what kind of compound is that?
🤔 i think it is going to emit too much noise. claimed 20% gain in efficiency is simply too much
I don't buy that efficiency claim either. BS
Appel pushes down pretty fast
UHB, Ultra High Bypass was what they called these engines back in the 70's, it's nice to see that they have come full circle to fly soon.
Strut braced wings and unducted fans. Next technological breakthrough, the double stacked wing.
As far as I understand it, these are probably a dead end design for civilian aircraft as they make a hell of a lot of noise - well above current civil aviation limits - and unlike current contained engines can catastrophically damage the aircraft if blades shear, especially if mounted alongside the tail.
The gear box is the big problem. No-one has managed to make a reliable gear box for counter-rotating duct-less fan engines.
Kuznetsov NK-12 from the 50s?
If the true and complete cost of flying was reflected in the tickets we purchased, would we still want to fly?
Derby, England. It is only pronounced Darby.
The fixed rotor section was used by Charles Parsons in his steam turbines, it is nothing new....
3:20… turbin??
This article mentioned shipping by truck/rail or if overseas by ship or by Beluga. What about the 747 with the 5th pylon for delivering an engine into remote locations? It's the only 747 with 5 engines. I believe it is still flying.
Is Antonov's big 225 still flying. I used to watch that beast on the deck at BNA Nashville and watch them load huge satellites into it. Watching it take off was watching an entire fleet leave the ground all at once. That was 20 plus years ago though, so.....
Mirya An-225 got destroyed in the first days of the russian offansive against Ukraine.@@jbrownjetmech-4783
Very interesting video, but this title and the video sample was in reference to exactly 1m31s of this 10m11s video, with almost negligible information about the "engine that will change aviation forever."
Whew till one of those bad boys throws a blade
Thanks.
"This Changes Everything."
great vid, but lol @ 'Darby'
What about the noise level. I remember a Russian model produced unbelievable noise.
The russian model used counter rotating blades. This does not. So no noise issue.
Antonov 70, with 4 D27 engines
@@GowthamNatarajanAI do you have some numbers? characteristics tables? sharing is caring!
You are thinking of the Tupolev TU-95 Bear, the reverse engineered Russian version of the B-52 Stratofortress, which is so astoundingly noisy, the US can track it via sonar from attack submarines. It’s that loud!
Ho hum, a old 80's idea that just keeps getting the spin. It's never going to happen
it will be good for tu95. surely it cant be louder than existing propellers... right?
Does it come with bolts?
What a weird narration. It went from the new amazing CFM to regurgitating the Rolles Royce engine video that has been on You Tube for years.
That engine looks like somethink from Ace Combat 7..
Somethink? 🤦♂️🤦♂️🤦♂️
What is the reduction in speed and altitude compared to a turbo fan. Maybe ok for short range Europe but not for international, Asia and US.
Carbon fiber props was Stockton Rush's idea?
"...old fashioned turboprops"
العمل والنشاطات والخبرات والتدريب والعمل والنشاطات
Yes, but not a touch on the mighty Turbo Encabulator...
There is no reason NOT to use props. Commercial planes fly subsonic.
Yes bit the props themselves can break the sound barrier at the tips
It also makes Julienne fries.
I would love to see what rolls Royce could accomplish with the budget of general electric or other big American companies
I wonder what would come out of all 3 or 4 companies getting together on an engine project. That would change the game forever.
Consider what happened when two of the greatest Airplane manufacturers in history got together; Boeing and McDonnell-Douglas. This bad marriage of Management styles resulted in their loss of leadership in the industry to Airbus. In their attempt to regain that leadership position, the Result was the Boeing 737MAX which killed almost 350 people in the space of a year. It isn't that they lacked the engineering capabilities or the capital to avoid such a thing. It is that they lacked the management WILL and FORTUTITUDE to put safety above next quarter's stock price. The way to see ever-improving technology is to force them to compete with each other and out-do each other in their quests to become the best. In Nature we call that 'Natural Selection'. Consider that when AT&T had a monopoly, communications technology was virtually frozen in time. When IBM had a virtual monopoly on computers, THAT technology, awesome as it might have seemed at the moment, was stultified by management growing complacent. It took the development of micro-electronics and innovators working with those new micro-circuits to achieve what we now have. Consider that a Silicon Valley startup is not only now the most valuable Car Company on the planet but is building the most powerful supercomputer on the planet.
Ehh, probably not. Too many competing means and methods and politics. It's not like they don't already understand each other's technology, all of which is a very well known quantity these days in those circles.
It looks like a slice and dice machine!
Why on the RISE is the second stage blade even there is the first place?
They have to come up with an efficient way to de-ice the individual blades.
Hello from “Darbyshire”
Derbyshire
I hope it's rad.
My fist guess was gravity is free
I loved always thoughts next-generation of
I call engines that give jet thrust and has an unhoused fan, an ExoTurboFan engine.
Hello Sir, I have one question. You are looking like above 40 but your hand movement is good but in my country here in India people are tracking wrist moment, using biological weapons and vibrations to force damage hand movement. Is it fair sir?
We had this already 30 years ago. The unducted fan didn’t take off.
This has been tried before. It was found that the noise from the counter-rotating fans was prohibitively loud....and at a very annoying frequency.
I believe the noise factor is the biggest drawback to unducted fan engines. Check out the 'Thunderschreech' X-plane with a supersonic propeller. It still holds the record for the loudest aircraft every flown!
that and lack of containment
Just one loose or weak screw...there goes 35 million
