You backwards fools still using Metric. Should switch over to the true Imperial system. Metric is only used by 94.3%(This number made up but should be close) of the world and makes people lazy because it is so easy and logical. Plus with metric there are less chances for mistakes and less drama so you metric using fools have to suffer driving over bridges and using infrastructure that is probably fine. No adrenaline rushes or mars orbiter crashes for you. Fools one and all.

Mark Sandstrom GE9X is able to produce more thrust than GE90 when pushed to the limit. They just proved that during testing. The lower thrust rating is in place to prolong engine lifetime and save fuel since the lighter 777X doesn’t need that much power
@@犬井いぬい are you sure that GE90-115B at triple redline makes less thrust than GE9X at triple redline? Neither would be a case that has anything to do with real operation in commercial service. And if the 9X's capability were that much, it would tend to indicate an over-designed engine that is either heavier and/or more expensive than it needs to be.

I built the GE90 from its inception to around the 550th engine. I was on the first team to build it. Built them for 18 years. It's an amazing piece of technology.
I’m not sure if it’s entirely accurate to state a 747 needs all cf6’s to stay airborne. Sure it would struggle to take off on a normal runway with say 2 or 3 engines, but once at cruise it can cope.
Hi....all multi-engine commercial a/c have to be able to perform with one engine in-operative. Hence on take-off the certificated performance includes assuming one engine fails (usually at V1 speed as most critical point).....so the 747 can take-off on three, the 777 on one engine etc. This is why with all engines operating (hopefully always) the twins typically climb faster than quads. Not everything about quads is bad, a twin with an engine failure HAS TO divert to the nearest airfield, whereas as legally a quad with one engine out can continue to destination or elsewhere
just as an intellectual exercise (it would be foolhardy plus illegal to actually do it) I'm curious about the case of 1-engine-out starting right at brake release at the beginning of the runway, at an offloaded gross weight and optimal center of gravity. but then you'd have to think about the case of unexpectedly losing one additional engine during that takeoff, and the exercise ends up being just chasing your tail... Possibly the true answer is, we cannot know.
@Claude Bedard Impressive indeed! Must have been a sight. I've not seen one fly yet. I have seen the Rolls Royce test bed 747 up close, HUGE does not come close to describing these monster engines. 👍
Just flew in the 777-ER for the first time ever, from Newark, NJ to Athens, Greece. Last jets I flew on were the Boeing 707, 747, and 737. The GE90's sheer power and thrust of that takeoff still leaves a smile on my face months later!

Coby, you did a great job here! Four terms matter in communications: Clear, Complete, CONCISE and Correct! You nailed it on all four, and kept it perfectly short-and-sweet. Nailed it! Proud of you.
@Claude Bedard Yeah, They kinda rushed in making it, Causing alot of flaws, It could've been better, But they had to ruin it, Because they wanted to show it as soon as possible.
Excellent video, Coby. 00:13 picture is actually a PW4060 engine. Way to differentiate PW4060 from a GE CF6-80C2 is the precooler outlet on the silver part of the aft cowling position. Left side of engine is PW, right side is GE. This rule applies to engines on 767 and 747-400 aircraft. I've had too much time on my hands looking at airplane pictures throughout the years.😉👍
This popped up. Thought it was new. It was not. It’s great to see how far you have developed your presentation. I think I discovered you 6months ago and I thought you had improved quite a bit since then. This video shows the full growth in 12 months. Well done to you! You should be proud.
I went to Line Replaceable Unit (LRU) training at the Customer Technical Education Center (CTEC) in Cincinnati in 1997 for the CF6. I was working on the KC-10 at the time. We got side information on the GE90 while there. There was also an ex test engine for training available on-site too. Those four foot plus long blades weigh nothing, especially compared to any other metallic fan blade. One of the other things they told us at the time was, when the first it went to the take off power setting in the test cell. The expected thrusted was supposed to be around 90K plus. Instead it exceeded 100k and they were just getting started. Oh yeah, Go Duke!
I’m not 100% sure but I’m pretty sure it was a GE90 I saw being hauled down Interstate 5 near Seattle on it’s way to the Boeing plant in Everett Washington. It was on a big low boy trailer and took up almost two lanes. The thing looked as big as a house. You don’t really appreciate how big engines like that are until you’re driving by one in a little car.

Im around GE90 powered 777 daily. The low tone the engines emit on start up literally vibrate the ground and can be felt within a 30m distance from the engines. It eventually settles into high pitch sound.
I've always wondered why boeing never considered doing a re engine of their 747-8i as a twin jet with 2 very large engines such as the GE90, it would require a new wing, but it would be so much more efficient. Maybe a new design based on one of these airframes would make more sense, but anyway, it would put these very large jets in a whole new category of efficiency.
Wider engines introduce a variation within a turn of the engine [fan]...higher speed incoming in the fuselage proximate air stream, rather than the slower general air speed away from the plane's body. This may be causing some of the challenging 'fatigue' failures in the fan's blades. '
The GE90-115B is an incredible! Very reliable , massive in size, and yes, 127,900 max pounds of thrust. Mates to the Boeing 777-300ER , a wide body craft and very reliable, comfortable. I’ve flown on this craft many times and it’s great! 👍

Come on Rolls Royce has ran engines over 120,000Ib too. The exclusive use of the GE90 on the 777-200LR and the 300ER was conditional on the Engine Manufacturer being responsible for partly bankrolling the the development of the Aircraft I mentioned. Both Rolls Royce & GE are pretty much on par with their Engine development.
Not to be picky but the 747 (VH-OJA) shown at 0:23 is powered by Rolls Royce RB211 engines. That footage is of its final landing at WOL for preservation, in 2015. This is located 20 minutes from my house.

2:28 that engine is actually just 123 inches in diameter, I can tell because the fan blades are not swept fan blades. Only the models with the swept fan blades have a 128 inch diameter. 3:01 that record has since been broken by the GE9X, at 134,000 pounds of thrust.
@3:32 "a 747 usually requires four [CF-6's] to stay airborne" I'm not sure in that; I don't recall a lot of 747s losing a single engine over the ocean and being lost as a result..
I don’t think the 777X is lighter - not sure about EOW, but I know it’s MTOW is actually the same as the 777-300ER. The original wing just really hindered the performance of the 777 by the time it grew to that size.
The 9X set the record for max thrust, its only rated at 105k lbs of thrust because that’s the max thrust chip installed. Just an FYI, the 115s are all down chipped to 105 now as well

Now since I got a job at Emirates to be a Pilot for the 777x that they have ordered they gave me a pretty long break that I’m kinda sad about since I love flying but at least now I get to watch coby explains videos😀
My fav plane is the B757. Still considered narrowbody, ETOPS certified for longhaul, 2 powerful engines (some may say it is overpowered), great for short runways and reaching high altitudes quickly when needed. It's my workhorse.
I remember when I was a kid in the 90s and seeing a 777 for the first time. I remember how massive the engines were at the time. My dad told me those were taller than a tall man and they were the most powerful engines in the world. I guess he wasn’t kidding.
3:36 - lies!! The 747 doesn’t “require” power from all 4 engines to stay airborne! It can do it with just 2, the others are for safety and redundancy! Also the GE9X is not as robust as the GE90... requriring a lot more maintenance and monitoring to make sure it’s running smoothly and more prone to engine failures (see 777X engine issues)!
Thanks for the metric conversions. It saved me the mental energy of converting inches to metres.
Of course! Now if only I can remember to do them for all my videos....haha

GE90: I set the world record for the most powerful thrust produced during testing

The bypass air plays a crucial roll of adding thrust. This was not known during the CF6 age. I’m surprised you didn’t mention this in the comparisons.

nothing, it is too expensive by fuel usage, and noise of bang, it is bigger chance to make all commercial aircrafts slower due to fuel consumption
Coby, you may have hit upon a great new idea : thru laminar ceramic 'needles' to act as interlaminar shear pins and perpendicular adherency boosters.

I am new to your channel. Your videos are fantastic. The content is excellent and you speak clearly with conviction. Please keep up the great work, as your channel will grow strength to strength. Cheers Dave from Australia ;-)
Thanks so much Dave!!
Hi Coby, you should do one on the various types of wingtip. (History, application, pros n cons)
This one's on its way! Ive already started writing the script - just need to proofread, shoot and edit!
Nice video !
Thanks again :)
It was a treat when I flew on United's Boeing 777 last October. What a beast.
Great explainer video, as good as wendover! Subscribed!
I'm excited to see what the RR Ultrafan can do
Only 16 fan blades on the GE9x.. amazing.
you could learn something today: boeing started with b767 wide body twin engines to overflight oceans, second rr made first non shrouded titan sandwich composite fan blades(ge/pw used solid fan blades with shroud)

Believe in JESUS today, confess and repent of your sins. No one goes to heaven for doing good but by believing in JESUS who died for our sins. For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.(John 3:16)❤️😎❤️😎❤️

Now since I got a job at Emirates to be a Pilot for the 777x that they have ordered they gave me a pretty long break that I’m kinda sad about since I love flying but at least now I get to watch coby explains videos😀
Coby: Don't forget to look up
Me: sees nothing
My favorite airplane is probably the dhc-2 beaver because it has such a powerful engine and can still take drag without slowing that much.
Wish I knew more about seaplanes....perhaps I'll do some research :)
My fav plane is the B757. Still considered narrowbody, ETOPS certified for longhaul, 2 powerful engines (some may say it is overpowered), great for short runways and reaching high altitudes quickly when needed. It's my workhorse.
@@gavin3598 You should check out my 757 video then (if you haven't already done so) :)
I remember when I was a kid in the 90s and seeing a 777 for the first time. I remember how massive the engines were at the time. My dad told me those were taller than a tall man and they were the most powerful engines in the world. I guess he wasn’t kidding.
I always had the doubt of why the GE9X would produce less thrust. Now that doubt is gone
You needed to talk about the investments of the french in this massive engine
I Love your Videos its so High Quality Plus thanks for Introducing me to your RUclips Channel
Thanks so much! Glad you're enjoying :) Got any questions you'd like answered?
3:30 talk about size comparison. ge90 vs cf6.
Coby can i ask u a thing? Which Boeing Plane Which is Your Favorite, The most Favorite Boeing plane u like pls
Isnt this engine almost as big around as a 737 Fuselage
2:40 welp there is the answer
do you have a resource on what makes that fan blade shape better? interested in the physics of it.
4 engines are not necessary to stay 747 airbone. 2 engines are enought. 2 of those engines have same thrust as ome GE90-115 engine
3:36 - lies!! The 747 doesn’t “require” power from all 4 engines to stay airborne! It can do it with just 2, the others are for safety and redundancy!
Also the GE9X is not as robust as the GE90... requriring a lot more maintenance and monitoring to make sure it’s running smoothly and more prone to engine failures (see 777X engine issues)!
Yup, It had 4engines since it was prior to ETOPS.
I'm flying on a All Nippon Airlines, does it use the GE90?
Depends! Is it a 777?
Steven Penny Only if it’s a 777-300er.
@@cobyexplanes Yes, 777-300ER
@@dr.stevenpennym.d.3241 Yep! It'll be a GE90
@@cobyexplanes Thanks Everyone !!
