I have not seen such a wonderful team of workers who take so much pride in their work in many other organizations. That's the ideal characteristics of a technology firm in the 21st century. You are the leaders!
27:54 I like Steve's enthusiasm for perfection, and his joyfulness. This, more than anything, shows how human emotion, not the absence of it, is at the core of anything that is made with such amazing precision and strength. In fact, what's more fascinating to me than the engine is the genuine integrity of all of the people in this documentary, and how much pleasure this kind of work brings them. I doubt there's a better way to live. Maybe different, but not better.
Everyone of these people are definitely masters of there craft. Beyond impressed by Rolls Royce. Makes me feel even safer when going up six miles high.
I think you're thinking of United Airlines Flight 232, that was a DC-10, and it probably had GE engines. There was one incident where an L-1011 had a similar problem but one of the hydraulic systems survived and no one was injured. There weren't any other engine problems, and that was one of the few times anything actually related to the construction of an L-1011 caused an incident. The DC-10 on the other hand.. That was the one where pilots really got to put those disaster skills to the test.
Thanks to series producer Steve Crabtree and Director Paul King for this outstanding program on Rolls Royce-- so intriguing, I cannot wait to watch it at least once more-- even as long as it is. There is no wasted narrative or extra footage in covering the mammoth complexity of the Rolls Royce operation and its suppliers. Particularly fascinating was not only the precise engineering of energy in each engine, but even the post-sale digital field monitoring of some 8,000-10,000 completed engines in regular service. What a tragedy it would have been for the company's finest moment, the birth of the Trent series engines, to have been eclipsed by a bankruptcy. All, going to show major advances in technology are never neatly predictable and spreadsheet-perfect affairs. * As a historical observation, the stunning and remarkable coincidence for BMW, manufacturer of WW2 fighter aircraft engines for the FW190, to begin production of the Rolls Royce luxury sedan, once the signature product of the same company which made Merlin engines for the Spitfire (Lancaster, etc).
I'm glad they didn't shutter the doors, who knows what the world would be without Rolls Royce engines and thee competition it forces to other engine manufacturing. Long live the royal engine of the skies... the true king of the air that carry the Queen herself and the Queen of the skies
Great video! Even as a pilot I never really realized all that goes into these engines! And did anyone else notice they stole the music from the movie Wall-E there?
At 28:00 the blades being shown are now made by 3D metal printers ... if i'm not mistaken. In any case, Rolls-Royce (and other manufacturers of jet-engines) are certainly using 3D printers to make similar blades.
When you think about the tolerances required to build both these turbofans and indeed the aircraft themselves, it's a staggering achievement... I remember reading about the design and building of the 747 and the entire aircraft are built to a tolerance of 1000th of a inch, the entire aircraft.. and those engines must be trebly so..let that sink in...
There are multiple different types of bearings holding the 3 shafts to distribute the axial and radial loads. Cylindrical and tapered roller bearings, ball hearings and needle bearings are the common bearings used depending on their funciton and placement.
Amazing work... Wow!! ? Just after 38:08 the narrator states that the main fan in flight spins faster than the speed of sound... Did he misspeak? I thought that all the fan blade components had to be subsonic in operation so they do not incurr sonic shock waves & break... Can anyone chime in on this? Thanks!
albert bahoogadin ... Thanks for the reply. There isn't much clear discussion on this. The thing that gets even more confusing is that the speed of sound or the Mach number is variable depending on the air pressure... Where in the compressor and turbine stages sound travels faster due to high pressures/density. How this effects moving components & combustion, I'm not sure. Perhaps the splitting of the spools & counter rotation in the new turbofans mitigates this issue by canceling out the resonance... Of course the larger diameter of the big thrust fan will make the blade tips move faster given the same RPM of the turbine components... This is probably why P&W introduced a planetary reduction gear for the final drive of the big fan increasing the bypass ratio... Quite a science in that. HA!
Modern day cars have a thermal efficiency of around 25% to 32%. Bypass fan engines from companies such as legendary Rolls Royce; thermal efficiency is around 97%. That is what I call engineering progress
just strap it to the top of the car.... hit that highway and blow past the cops.... enjoy the high speed pursuit they would need chopper and have to set up spike belts miles ahead to catch you. but once your tires blow out at that speed... out the front window you go a few thousand feet. Definitely not survive that one. Would be a blast (no pun intended)
They make it sound like all the components are made in the UK.. They are certainly not. I've worked on over a hundred GenX Fan hub frames at Volvo Aero Corporation in Sweden. We make what the others can not =)

Trick question, it really depends on what you're planning to use the engine for, if it was for a tractor you'd want something with a lot of low rpm torque such as an electric motor for an aircraft or ship you'd want something with lots of power and a constant speed like a turbine engine or some jet. As for hydrogen, in theory it could work in any combustion engine, since hydrogen would actually be the fuel, there's an episode of mythbusters where they run a conventional piston engine on it.
The Boeing 787 in beginning at Paine field is the Boeing plant thats located in Everett, Wa. Not Seattle. Than they still go and talk about the weather in Seattle.
Very good documentary but it still missed out the names of a few keyparts. The "brain" of the engine is know as the FADEC (Full-Authority-Digital-Electronic-Control)
They forgot to mention, do not mount defective stub pipes. They did in the Trent 900, which caused an oil fire. The engine caught fire, a turbine came apart and pieces severely damaged the landing system of a Qantus A380. The Qantus crew saved the day. If Rolls Royce does that one again they will be out of business.
Just researched that it was an intermediate pressure turbine disc failure,but surely the engine design should be such that fragments are contained within the engine environment...
It's interesting to watch this from the puget sound. In so many ways this area's relationship with Boeing mirrors that of Rolls Royce to Darby. Almost everyone here knows someone who works or has worked at Boeing. But where RR seems to be committed to it's roots there Boeing isn't & I think it shows. Each year it seems now Boeing is less and less well liked. Where Rolls seems to find success focusing on the development & production of engines and the like. Boeing has not, contracting out as much
I noticed that there are no muslims or africans contributing their massive intellectual skills to the project.........i guess they are too smart for this line of work..
