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.

just flew on it 3 days ago. after a long while of no flying, in the moment I think its pull soo hard, but probably the normal take off acceleration. now when I look it up, omg, I just experience the holy engine take off.
@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.
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. 👍
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.
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.😉👍
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!
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.
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.
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! 👍
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.

When I worked at Delta, a 777 pilot was so proud of his aircraft, he had a fun facts paper he would give to anyone who came to the flight deck. One fact was the a single 777 engine could supply electricity to 25 homes!
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. '
@@user-hm2jb6ed5k whats your point? Etops of 330 minutes. British airways had a different fuel heating system that caused the problem. Wasn't the engine.

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.
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.

Nice breakdown of the GE90! Curious about your interest in things aviation. Is this a hobby for you or do you have some sort of professional relationship to the aviation world?
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😀

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
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.
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.
@3:32 "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..
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)
So lucky to have stood inside the GE90-115B engine , while the engineer took a picture of me 🤣🤣 question , why doesn't the 747 use 2 GE90's , instead of the current 4 engines it has ?
because the 747's wing is optimized to handle a distributed load across the entire wing. Sticking two engines on instead would localize the weight and risk aerodynamic instability/wing cracking. Would be cool to see, though!
This is a really good one actually, especially considering they almost went bankrupt to push the entire industry forward. Will start working on a script!
When you consider that the 777-300ER is a larger aircraft than nearly half the 747's built - certainly larger than the 747-100 General Electric formerly used as a testbed, one moving that lightly loaded testbed through the air on its own isn't a particularly big deal.
After thinking about thrust and jet engines, it seems as if the actual thrust comes from the intake fan from the front. The jet stream in the back is a by product of the thrust which is actually from pulling the plane forward through the air…IDK….any thoughts?
The new GE9X which is going to be used on the 777X recently proved to even more powerful than the GE90. The GE90 produces 128,000 lbs of thrust and that’s a lot, but the GE9X put out over 134,000 lbs of thrust on a test. The GE9X is the NEW most powerful engine!
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.
GE90: I set the world record for the most powerful thrust produced during testing
GE9X: Hold my throttle
Well, looks like a follow up video is in order haha
the GE9X actually makes less thrust than GE90-115B, because the new wing of 777X improves performance enough to reduce thrust requirements
Mark Sandstrom what I was stating was at triple red line testing
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

Nice breakdown of the GE90! Curious about your interest in things aviation. Is this a hobby for you or do you have some sort of professional relationship to the aviation world?
I'm excited to see what the RR Ultrafan can do
Thank You !!! 😁
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😀
One rare video where Coby is not wearing a cap (oh and that is the 400th comment here 😀)
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)❤️😎❤️😎❤️
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
Hey man great video!
3:34 The 747 does NOT require 4 engines to stay airborne, no matter what engine it uses.
A very good aircraft with wider aisles,Toilets,Silent and smooth take offs and landings.
A perfect airliner by any standards.
Only 16 fan blades on the GE9x.. amazing.
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.
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.
@3:32 "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..
GE90: I will be the most powerful engine for years
GE9x: Hold me beard
Nice and awesome video sir👌
Excellent explanation 😉😉😉😉
You got a some facts backwards (3:45)...747 only needs 2 engines to stay airborne..not 4.
Other than that...you're spot on.
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)
Nice video !
Thanks again :)
So lucky to have stood inside the GE90-115B engine , while the engineer took a picture of me 🤣🤣 question , why doesn't the 747 use 2 GE90's , instead of the current 4 engines it has ?
because the 747's wing is optimized to handle a distributed load across the entire wing. Sticking two engines on instead would localize the weight and risk aerodynamic instability/wing cracking. Would be cool to see, though!
You needed to talk about the investments of the french in this massive engine
I always had the doubt of why the GE9X would produce less thrust. Now that doubt is gone
How about a video on RR and their history on engine manufacturing
This is a really good one actually, especially considering they almost went bankrupt to push the entire industry forward. Will start working on a script!
Dank Fuk RR and their junk engines !!!!
Good stuff thumbs up
Thanks! glad you enjoy
Coby: Don't forget to look up
Me: sees nothing
When you consider that the 777-300ER is a larger aircraft than nearly half the 747's built - certainly larger than the 747-100 General Electric formerly used as a testbed, one moving that lightly loaded testbed through the air on its own isn't a particularly big deal.
After thinking about thrust and jet engines, it seems as if the actual thrust comes from the intake fan from the front. The jet stream in the back is a by product of the thrust which is actually from pulling the plane forward through the air…IDK….any thoughts?
The new GE9X which is going to be used on the 777X recently proved to even more powerful than the GE90. The GE90 produces 128,000 lbs of thrust and that’s a lot, but the GE9X put out over 134,000 lbs of thrust on a test. The GE9X is the NEW most powerful engine!
I clicked on this video not cause I want to know about THE GE 90 but because I like this channel and am obsessed with THE GE 90
preach :)
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.
I’m getting that ASMR feel from the mic on your jacket 🤣
The GE9x broke the record for highest thrust tho
Guess I'm going to have to make a new video haha
@@cobyexplanes it's OK it's rated at 105 only 😂
