Absolutely great video! I'm an aerospace engineer and was the original mechanical design leader of the GEnx-1B fan blade at GE Aviation in Cincinnati. The video and appreciation of it in the comments are really amazing and I'm glad to see so many people interested in it. Working with the great team at GE on this project is my proudest and most rewarding career highlight so far. There is so much engineering and amazing testing on all these components that they could each be their own video. Watching the CFAN team in Texas do the hand layup of the hundreds of carbon prepreg plies for each blade in this video brought back great memories. Just a couple suggestions if you want to incorporate them: First, the actual spelling is GEnx (not GEnX or GENx). Also, the LP system (fan, booster and LP turbine) are all on the same shaft and spin CW (as viewed from the front). Some of the animated cross sections in the video appear to show the booster and LPT spinning CCW. The HP system (HPC and HPT) are on the same shaft and spin CCW. It's a counter-rotating concept, unique to the GENx for GE turbofans and was intended to increase performance and reduce parts count. It's the only GE commercial turbofan to have the LP system spin CW. Some mention of the fan blade out requirements might be warranted. Fan blade out loads play a large role in sizing all the primary engine structures. The unique carbon fiber fan case of this engine is sized strictly to contain this event and keep the blades from leaving the engine Moving from 22 blade to 18 blades as mentioned was a concern on how big the blade out loads were. The fan blade out test required for certification is the most severe test there is and of course pretty much destroys the engine. Thanks for the great video and sharing the amazing engineering that we can do when we we put our minds, energy and passions to it.

I just flew in a 787 for the first time today, and I kept remembering different features of the plane that were described in this video.

@ASJC27 2 роки тому
A couple of small corrections: At 3:25 - an air starter doesn’t feed air “directly through the turbine section”. It feeds air to a separate small air turbine that is geared to the main shaft to spin it. It is just like the cartridge starter, except the starter turbine is fed compressed air instead of combustion gases. 17:13 - the term is pressure ratio, not compression ratio. Compression ratio is a piston term and is a volumetric ratio. Pressure ratio is a jet engine term and is just what the name says. You use the correct terminology later in the video. People may think that they can compare these numbers with piston engine compression ratio but they can’t be compared directly. They describe different things.

Aerospace engineer here. Great overall work with the video! Just have one thing to ad, at 13:10 it is stated that there are only one shaft in the GENX. The usual configuration for turbofans are two or three shafts stacked. In the case of three shafts (which looks like is the case here from the low pressure turbine config due to the slightly larger gap before the last low pressure turbine) connecting the HPC-HPT, LPC-LPT1 and FAN-LPT2.
@EdwardPallett 2 роки тому
It's a 2 shaft engine. The low pressure compressor is on the same shaft as the fan (not clearly shown in the diagram). The only civil wide body jet engines that are three shaft are Rolls-Royce Trents (incidentally the RR Trent 1000 is an engine option on the Boeing 787)

Look up "Chrysler Turbo Encabulator". It kind of speaks to what you are saying there, among other things. Finish swallowing whatever you are drinking before you start the video, though. I've shown it to a few non technical types, just to see how long it takes them to catch on. Most engineers or techs/mechanics are laughing from the first 'explanatory' sentence. The one with the maintenance feature at the end is the best, and those search terms should get you there, because that is the exact title. With YT, you never really know, though. If you do, enjoy. :-) IIRC it may have been done by some engineers at one of the major companies, don't remember which, been too long, or maybe even one of the companies themselves, maybe even Chrysler. Nerd humor, but GOOD nerd humor. Crap, now I've got to go watch it again. The funniest part, for me, is they used to make a great transmission called a Torqueflite way back in the 70s. You'd ask people what the difference was and they'd just kind of give you the 'who knows' sign. They were good trannys, although my dad managed to split a planetary carrier on one of them.

These new efficient engines cause flight instabilities on modified planes like the max or the 777x which even scared the FAA who will not review them in flight after a flight test pitched toward the ground like the MAX. A hundred Dreamliners are grounded suffering from quality issues. Inferior titanium that passed initial QA. Oh forgot this weeks issue that affects all past and current dreamliners. The carbon fiber wings and fuselage are made with contaminated carbon fiber. Boeing has a sht show like the world hasn't seen in some time. These ultra efficient engines are huge as the high bypass design has those huge Turbines in the front. This cause modified planes to have to move the engines forward and upward with the edge neat the leading edge of the wing. This was why they use MCAS in 737max and something similar in the modified 777 the 777X. Most Airbus planes are much more recently developed with higher wings that provide proper clearance and are stable in flight. The Dreamliner if it was done properly is also a much more modern design but every one made has major issues. The people who work on the Dreamliner assembly line in SC have said in interviews, "I would not allow my family to fly on that plane". Regarding the insane engine...They are over-stresses as the huge turbine creates huge centrifugal force and bladed if not perfectly mounted, break. Boeing is replacing the shrouds that the FAA cited as being to weak to full contain a turbine failure.

Thanks for the great content! In my time as a contractor at GE in Cincinnati, I helped do CFD for those 3D-printed fuel nozzles and for combustion chambers of the subsequent products that built on the technology of GEnx: the LEAP and GE9X. They were insanely intricate and pushed the state of the art for jet engines. Predicting combustion behavior is also totally a black art. I was humbled by the absolute geniuses they had working on developing the statistical models that I fed into my analyses. @17:43 One nitpick about thermodynamic concepts, here: Maximizing pressure ratio doesn't "maximize" the amount of energy you can extract from the fuel... Adding heat through fuel burn increases enthalpy (H) *isobarically* with entropy (S); think about the 2nd leg of the Brayton cycle as drawn on an H-S diagram. Fuel has some specific energy and you could achieve the same dH for a given fuel mass, because we're still talking about the same specific heat, Q, being imparted to the working fluid. Compressing the air more just starts that process at a higher initial H, but that also increases its T, meaning you'll be actually able to add *less* heat before hitting your turbine material thermal limits. This still improves efficiency because the more the cycle increases H by compression than by combustion, the less fuel is necessary to make up the difference in total energy needed by the complete engine cycle. Thermo is fun!

Me friend told me the first time he flew a sailplane with composite wings it was frightening him half to death. He said to him it looked like 10', at the tips. They definitely are not designed to act like metal wings. If metal wings DID act like that, they'd be separated from the fuselage in pretty short order. I hate it when that happens. Hell, even when metal wings hardly move, at some humongous number of cycles they start to crack, and weaken, hence metal airplane useful 'life' specs. It's called metal fatigue and I expect it happens due to, at best case, large crystal interfaces, usually probably just material weak points or manufacturing 'defects'. I expect that is one thing the single crystal blade does for you, that and it is strong. Multiply crystalized grain boundaries weaken things, and those are at microscopic levels.

Awesome video! Minor point, the chevrons on the fan increase the exit area of the interface between ambient air and fan discharge. Increasing the area decreases the shear which decreases noise. Think of a siren, it makes high pitch noise by shearing the air. We experimented with chevrons on an unnamed fighter engine with no real benefit in noise reduction seen (no comparison implied, different application). Fan discharge air reduces the shear between ambient air and the core by accelerating the air at the interface of the fan/ core discharge. Reducing shear reduces noise. BTW, loved the video so much I subscribed to Nebula.I learned a lot. Love this systems stuff. Also loved seeing "my engine" in the test cell in some clips.

It has 3d nickel based printed parts in this nozzle which I was, and still am in awe of when I looked at it. There is a fan type stationary blade system built into the nozzle which swirls the air when the fuel is introduced making for an extremely atomized fuel delivery system. This swirl was never introduced to the petrol engine until late into the combustion chamber on a IC engine and then not until the last couple decades. (I believe) :)
@brettkemp4219 2 роки тому
@@tomcoon9038 You're correct, Tom. I was only comparing the two in the most basic concept of air/fuel mixing. The swirl (therefore better atomisation) actually started in a well designed inlet manifold and upon entering the offset inlet valve throat thus swirling and giving a denser more complete charge in the cylinder/combustion chamber. You would be surprised at the gains made on the dyno after working the manifold/port configuration. No need to do as much any more as atomisation occurs differently in modern EFI engines.
@bahenbihen 2 роки тому
I completely agree. The swirler however was first introduced for better heat distribution in annular combustion chambers as that would decrease the thermal stress on the (HP) turbine.
