With its huge variable pitch fan, this engine really blurs the line between a turbofan and a turboprop.

The U.K. continues to punch above its weight with the Rolls-Royce units. Impressive! This video is an advertorial for Rolls-Royce, of course.

Gagging on green. A geared fan engine that will run on bacon grease. The world is saved.

Poor pigs though!

The Ultra Fan looks to be a ducted turbo prop.

Geard fans have been around for a long time it's nothing new. And not really a prop.

GE's GE9X produces 134,300 lbs thrust. How much thrust does the Ultrafan produce?

The engine should be able to handle non-stop Heathrow-Sydney flights with the potential to allow for non-stop Heathrow-Auckland and Heathrow-Christchurch flights.

I wouldn’t go near one of those flights. The question is why would I?

GE9X hasn`t been released yet & RR`s UltraFan is far from being considered by Boeing or AB. The most efficient turbine built thus far is RR Trent XWB -84 & -97 these two engines power the A350-900 & -1000 respectively & will do so for some years to come. XWB has been proven to be very reliable & has helped the company to become more profitable since the pandemic & the debarcle that was Trent 1000 issues that did RR so much harm is now a thing of the past with those issues sorted. GE9X will have to prove itself when B777X is launched but that could be some time off yet but it could well surpass XWB efficiency. UltraFan could well push the boundaries further but until either Boeing or AB want this engine for a particular aircraft RR will be reluctant IMHO to invest funds.

Since 2014, its a test bed engine. No longer intended for production in its current form and is not available to airframe manufacturers, although it could be scaled down for narrowbodies. According to RR press releases a year ago, technology learnt from the UltraFan is being transferred to current engines, ie the Trent series, so expect some announcement for upgrades to those XWBs at a suitably propitious time, like when the B777X finally gets certified, when just maybe Airbus then announce improvements in performance to the A350 at the same time...........

That's freakin' fantastic. We can all fly around loads more now 🤣

Will these now appear on the new Globemaster or the the A380 Neo ?

'This Airbus A350's “MASSIVE NEW ENGINE” Will Change The Aviation Industry FOREVER!' - because the geared fan engines fail permanently and have to be checked with a lot of amount. The next generation of engines will get a larger diameter than the fuselage.

Actually the passengers will be sitting all around the circumference of the engine , A flying engine instead of a fuselage 😅 Just upscale the similar fighter jets LOL

I'm wondering how RR thinks the Ultrafan engine will be adaptable to narrow body aircraft when its diameter is so large? It will be interesting to see how they do it... IF they can!

How do you keep cooking oil from freeing on 35000 ft at Negative 200C° modern Aviation fuel has additives to antifreeze and cope with any kind of situation to continues supply of steady flow. Cooking oil need to be well developed to do that in the future.

Your ignorance is laughable. Saf ain't cooking oil for a start. And -200°c way to pull a random number out your ass. -56°c if the lowest temperature aircraft encounters. And if you really wish to know, go ask British airways, airline that's been using it for 3 years now.

But it's not a given he ultra fan will power future A350 variants!!

That AI commentary is SO annoying

Help me understand. This engine is the diameter of a 737? How will it fit on the wing??

Well maybe because it's not made for a737 in the first place. Just like the GE90 or Trent 1000 it's meant for large jets 🤦🏻

⁠the engines on the 737 don’t matter. You need a parachute when flying Boeing these days. Never know if you might get sucked out of a door or have some electronic system crash the plane! I now check the planes a route/airline is using and select a flight with Airbus over Boeing wherever possible.

Why are you sure it is forever the industry will change??????

Yeah that's not how it works. Most modern jet engines can use SAF it's the entire point of saf. This is just far more efficient because of the larger bypass and gears fan.

It is physics and unfortunately real

Some wealthy countries (like the US) are developing the methods and infrastructure to mainly supply their militaries with an alternative fuel source, and the airlines are piggy backing on that. "Green" jet fuel is not economically viable at the moment, it's too expensive and hard to produce for widespread use. "Green" jet fuel also has to be produced and refined to be an exact replacement for current gas turbine/jet engines. The engine makers are not going to modify their engines to fit your alternative fuel, sorry, doesn't work that way. So it's not a selling point, it is a requirement.

@rogerphelps9939

Ай бұрын

If you calculate the amount of land required to produce biofuel to power just one A350 you will find that it is huge. Fuel synthesis using green electricity may be better but then you have to consider the number of big wind turbines necessary to supply one A350. It is a lot.

Pure Speculation! Where are the facts?

Any jet engine can use sustainable aviation fuel like GE engines that attached to 777-9.so it's not be brannded to airbos.

Computer narration is getting better, but this one still sucks.

BLUE fan blades !! That's groundbreaking stuff

I think Airbus is causing too much stress for Boeing?
