- GE90-115B inside and out
I hope you guys are ready for a very long video, this was much asked for from everyone and I decided to make a more organized and detailed video about component location and functionality. As I said in the video, it’s almost impossible for me to fit all the information into a short video. There is a lot more going on within the engine then what I explain. But it gives you a glimpse behind the scenes and underneath the cowlings.
feel free to ask her questions, and if I made a mistake anywhere here, please feel free to correct me as well. One thing I will tell you is that I am not a know it all, I am a student of aviation, and I’m always learning.
thank you for watching. Have a beautiful day. 🤙

Airline pilot here. A big thank you for everything you do! ❤
My pleasure sir. Thank you for your hard work as well. Appreciate you stopping by and watching
Thank you so much for this video. I actually work for GE Aerospace, building the GE 90 at the Durham Engine Facility and I probably had a hand in building this particular engine. It's awesome to see someone appreciate the hard work we put into these beasts. Great job explaining everything as well. It's great to see the finished product hanging on wing compared to what we normally see after assembly. Much appreciated.
Thank you for all your hard work and dedication for building this beautiful engine. It’s an absolute pleasure working on it. Send all my best to all at GE technician in Durham. And Thank you for being here, I appreciate you.
What’s up Stumpy, I built them too, in the same spot.
@@Bigfish1day Yes, and you were on my team as well.
@@stumpygnome1834 😳😲
@@stumpygnome1834 Oh damn, what up teammate 🤣🤣
Im a fueler and you are right, there's nothing more humbling than to stand in front of these engines. To think these can make over 100,000 hp each, is simply mind boggling. Thank you for showing it to us and also kudos to you who fixes them, and to the engineers that designed them and to the people that built them. Takes truly brute force to propel over 600,000 pounds of plane to 600 mph for thousands of miles. Very durable and they don't smoke at all.
Well said!
Mind boggling these things actually work Can we have a simple engine with one hundred parts only
Don't worry about the video being too long. Take your time and explain everything nice and slow that is easy to catch. Its interesting to learn. Your doing a great job. Keep up the good work.
i appreciate you
Well said dude. If someone finds this video long it is because they are not into aviation like we are. Im not a pilot but I love it!
It's astonishing that you people's are doing great job in maintaining the aircraft engine and lots responsibility on your shoulder rest till the aircraft lands with cargo and passengers. Great
Airline passenger here, thank you for all your skilled work you do to keep us safe.
It’s my pleasure sir. Thank you for watching and enjoying
This is the coolest video I'll watch all day. I thank you all for keeping these birds flying safe in the skies. Can't wait to see more content. Cheers.
i appreciate you being here and enjoying
What a privilege to be able to watch an engine inspection with explanation on TH-cam 💪 thanks man, love your channel
Thanks for watching!
Been a commercial aircraft mechanic for over 35yrs and the triple 7 is just amazing. The diameter of the engine cowling is the same diameter as several commercial aircraft fuselages! Giant! I had the pleasure of standing inside the engine cowl years ago and I couldn't even touch the upper intake cowling!
It’s a humbling experience when you stand inside the intake… first time I did that, I felt like a little ant next to an elephant.
Excellent video. Well filmed and explained. During the last 5 years of my career I worked solely on these aircraft/engines and as you said they are so reliable and a dream to work on. In fact I was working on the freighter version and they could be away from base for anything up to a week having flown multiple sectors and many many hours and arrive back with nil defects and none while it was away either. Brilliant aircraft.
Well said
That's fantastic reliability. No wonder each engine costs more than a whole regional airliner (I think).
This was the fastest nine minute video I ever watched. I'm a gear head and this was so interesting I wished it was an hour long. I recognize the detail and pride displayed in the manufacturing of this beast. I'd really like to see one in person. In addition, you explanation was spot on, thanks.
I’m very happy you enjoyed it. Thank you for being here
thank you for keeping us safe.. I fly a lot on 777s across the pacific ocean, super poweful/reliable engines and well maintained
It is my absolute pleasure, thank you so much for watching and enjoying these videos
I’m glad we have people like you that work for us!
It is an honor and a pleasure to work here. I love this job
Thats i stick to american airlines 😊
I remember watching GE test this engine on their 747 in Mojave. On one of the runups on the hammerhead it caused a boulder to roll away.
i seen those test first hand
The G90-115B is a superlative aviation engine. This presentation was pithy, as well as insightful.
Massive respect to all the designers and production engineering personnel!
Thank you very much, im happy you enjoyed it
I'm an automotive technician I work on ford 6.7 powerstrokes. I literally just watched all your videos. Very amazing engines. Maybe I should do a career change. You just gained a new sub! Keep up the awesome work.
Thank you very much! and its never too late to join aviation, your experiance as a wrench and troubleshooter will apply well
@@StigAviation tha ks for the feedback! I do have a request if possible. Can you show a brake change
@@BeardedFordTech absolutely, got the video ready 👍
@@BeardedFordTech Just uploaded it... enjoy ... let me know what you think
That was amazing! Thank you so much for showing of all this ! Flight maintenance is sadly often overlooked but those kinds of videos are the ones that make me love aeronautical engineering! I would love to watch a longer video about all of that, maybe going more in detail (perhaps with some schematics if you're allowed to show us that) !
Thanks once more for the amazing work !
I’ll do my best to show more In depth information. It’s just very time consuming to put it all together. But I’ll definitely do my best
Merci pour cette visite très intéressante. Un grand respect aux ingénieurs et techniciens qui ont conçu et entretiennent ce magnifique moteur. Le 777 est un super avion !
❤️From France 🇨🇵
Thank you so much for your kind words.
This is GOLD! I've never seen a GE90 So up close and explained in proper detail! Hope to have more videos!
Glad you liked it! More to come 👍
Engineering is a wonderful mirror of men & women's intelligence, allowing people to enjoy all the benefits from Technology. Particularly the aerospacial Engineering.
Well said 👌
You definitely love your craft. Keep wrenching and keeping us safe in the back and the cockpit. Always fun to have you guys up front for a conversation.
Always! Thank you for being here. I appreciate you
I am an retired AF jet engine technician. Never got to work on GE engines. I was all Pratt engines. I was on the C-17 for 13 years, and they have pretty much the same components under the doors. The GE 90 is an amazing engine to say the least. I work at an airport now and I always stress to other do NOT drive behind a running jet engine!. Good job on video!
Thank you very much Allen. I appreciate you being here and watching, and thank you for your service.
The first time I ever boarded a 777-300 as a passenger, my seat was right next to the engine. I opened the shade and looked out the window and there was a man standing in front of it, as well as a cargo van. Both items looked like they could easily fit inside of the engine. I was floored as to the massive size of that beast. But then, you look around the aircraft and realize just how huge the airframe is and that one of those engines has to be able to power this beast by itself, it's completely proportional to the aircraft. Ever since that experience, I have been a huge 777 and GE90 fan.
The video itself does not do justice to the size of that engine. It’s incredibly massive.
You’re so good in explaining and showing things so clear, that’s for those amazing efforts you put to show the world your passion and enlightening us all..Love from Australia 🇦🇺
Thank you so much and I’m very happy you are enjoying it. Cheers from LAX
Thank you for sharing.
That is great. Just started watching but i love learning about those things as an avgeek, near future flight attendant and possibly pilot a bit later on
Glad it was helpful!
A man who loves his job! Not only is airliner science amazing, but your knowledge of their systems is commendable!
Thank you so much Steve, I’m glad you enjoyed it
Amazing wonder engineering Marvel that flies us .I am grateful to this engine,it's makers and technicians who take care of them.Thanks for showing this.
It’s my pleasure. Thank you for watching and enjoying the world of aviation.
I really love your video as much as you can imagine! It’s really awesome. Thanks for your time and dedication in the making of this 😄
Thank you very much!
I always wanted to continue my aircraft technician career after the US Air Force, but I moved on to a different career. I've always been fascinated by airplanes and working on F-15E's for 10 years was the highlight of my life. Thanks for this video!
I’m glad you got to experience such incredible machines Thank you for being here and thank you for your service
This is turely a nice quick tour and components explanation, looking forward to your next video.
I used to work on the GEnx and CF-6 series, they're good design engine as well.
thank you so much for being here
Great explanation video. Reinforced a lot of systems I know but have forgotten about. Thanks for the re-education!
I am very happy that you enjoyed it Richard, thank you so much for watching
When I worked for Ford I wanted to get into aviation (early ‘70’s) but I was told I couldn’t compete with Vets returning from Vietnam so I didn’t peruse my dream… pilot or mechanic. Thank you for your time & expertise Sir.
I’m glad you are here enjoying it but I wish someone in the past didn’t discourage you from following your dreams. The industry needed mechanics back then as they do now.
@@StigAviation I eventually applied to Falcon Jet for a mechanic’s position. The interview was a joke. They gave me French schematics & he said it didn’t matter, “you should still be able to read them, which I agreed but said I didn’t read French. Then they gave me ‘a soldering test.” Now I’ve been soldering well over 10 years & was quite proficient in it but they gave me a 50W pencil iron & asked me to solder two battery cables like 2 gauge & I knew it was impossible. Before I even started I told them it won’t work without more heat like 500W or a flame from Bernzomatic. He made a rude comment & I knew I was wasting my time there.
Im a supply Technician. For more than 27 years... when we taking care of all Aircraft Parts. Up to now... i cant compare my self as the Maintenance Technician...they are the True Legend 🏆🏅 ..
You wouldn't believe the intricacies of the tools a maintenance technician uses
Imagine they are fixing something that was invented....you know drive how to drive a car...but can you make something like it?
This is the case with the maintenance technicians who make these planes fly..as for the pilot, he is someone who performs a job similar to driving... With all due respect to the pilots and to all aviation workers... But from the many years of experience, the technician is the backbone of the world of aviation
Salute 🫡 my friends
Thank you so much for Sharing this episode.... we value the efforts you are doing 👌🏻 👍🏻💯
Greetings from Kingdom of Saudi Arabia 🇸🇦 and
Thank you for such kind and inspiring works. I’m humbled. Thank you for being here. I appreciate you
Not in America you are the scum of the earth because as far as management is concerned you are costing them money on the bottom line ,I retired after many years in this crappy business
What a piece of masterpiece. When I was studying fluid mechanics as a mechanical engineering undergraduate student, I came across your video. I will hopefully either be an engineer designing these machines or a pilot flying them. Thank you a lot for enlargening my vision, being a guide and reminding me how great decision it was to choose mechanical engineering.
I am very happy you enjoyed it and I’m glad you learned something new. Thank you for watching.
I’ve worked the 777 for about 5 years now. Mostly quick turns, I’ve yet to have a need to open the cowlings. It is a master piece.
When you get the opportunity to open it, make sure you saver every moment, it’s absolutely gorgeous
@@StigAviation we opened it up during school, brand new… is truly a masterpiece. Crazy latching . I’ve spent most of my career with the CF6’s… the 90’s dad.
Im excited, I just ordered GE90 -115B for a conversational piece for my living room.
What scale model did you get ?
Sorry I was just kidding...lol
amazing machines running 24/7 flawlessly pretty incredible
It always amazes me how efficient they are
I can't say thank you enough for doing your videos. I'm a pilot that never made it to the airlines and always have a ton of questions how about the big iron. Super awesome to have some of these questions getting answered. Amazing. Thank you for having such an upbeat personality..
Thank you so much sir. I appreciate you being here and enjoying it all
Excellent presentation Stig. It's very obvious that you take great pride in your job. Keep up the good work! Long live the Ge90115-b1
Many thanks!
Excellent description of this engine! You did an excellent job showing and describing this engineering wonder! You gotta make long-term videos about these engines!
Thank you very much! And I got a few of them so far. Thank you for watching
Amazing video that have a lot of informations in it, i am starting my university journey in aerospace engineering so this is a good start to look at
keep up the good studies
Thank you so much for taking the time to give us a tour of this monster engine. All your videos are wonderfully done.
Thank you very much!
This was my first video I’ve watched of yours. It’s so hard to really grasp the size of that engine and the word MASSIVE even seems small. I’m so used to to looking at my car’s engine that I didn’t realize just how much is underneath that bad boy. I always fly 737s. I’ve unfortunately never gone overseas but I’m glad there are people that know how to service these engines and take pride in their work. It’s because of people like you that always keeps are skies safe.
Thank you so much for the kind words and yes indeed Massive is an understatement for this engine. It’s truly mind blowing when you stand next to one.
@@StigAviation I’m glad you got to read it. I thought maybe you wouldn’t see it. You definitely take pride in your work and it’s really great to see that side of the world so-to-speak. There are so many details you have to know. It was just an awesome video and I subscribed because of it. Thanks for taking the time to reply :)
Thank you so much. I travel very frequently on B777 clocking 11000 miles each way. I put my complete faith in these engines. Absolute workhorses. It’s nice to understand how they work. Keep us safe and aloft for 13 hours nonstop.
Glad it helped give you assurance. And don’t worry we will keep is working 👍
Outstanding video, good narration, GE has great reliability. Aircraft techs are the unsung heroes of the industry, keep up the good work.
Will do. Thank you Sam
It’s too bad you skilled technicians are disrespected by management and look at you as a liability to the company’s bottom line and don’t pay you for what you are worth
All technicians are considered the "last wheel of train" it's not important how many have you studied and specialized the mass of people see your dirty hands and considered person that turn the scredrivers.
good news is they can't fly without us... we fix they fly
@@StigAviation I have worked as a technician A&P for 38 years and retired management will simply sign the squawk off or get someone else to do it You can’t win in this crappy industry
@@mikethompson3534 it’s changed a lot since then Mike. Things have gotten better. Accountability, transparency and safety is what they push for nowadays.
What a beast of an engine. May I ask a question my friend . How much does one of these weigh?.
Its 2am, i cant sleep and YT sent me here. But at least now i can service a GE90-115B without hesitation next time my flight is delayed. Thank you sir!
thank you for stopping by i appreciate your time
Recently retired MIA 777 Captain. Thank you for this excellent video, and thank you for your diligent work.
Thank you Captain... and thank you for your years of service.
Thanks!
Merry Christmas man to you and your loved ones!!! Please keep the good work, the videos are great…
Thank you so much Andreas for your generosity, I appreciate you, merry Christmas to you and your family and a very happy new year.
About to bid 777F at my airline. Been on the 767 for 8 years. 747 before that. The GE-90 is a massive work of art. So much respect for the techs that keep them running safely on ETOPS flights.
You are definitely going to enjoy the 777. It’s a very good aircraft n
Stig I love all your videos so great to watch what you guys do to keep us all safe . You do a fantastic job . Keep up the great work .
Thank you Jeff I appreciate you being here
Awesome walk through 💪🏻
Glad you enjoyed it
You worked very hard on this video Stig. Thank you so much for posting. I’m certainly going to watch this over and over again before I even begin to ask you any questions about it. Absolutely fascinating. Thank you for putting the effort into making this video and for sharing it with us. GE90-115b. Fantastic engine 🥰
iJeff348
Wow, thank you
Really interesting, thank you for all of that!! -- I am always fascinated by redundancy in systems like this.. Redundant hydraulics, generators, engine control + watch dog systems all so amazing
It’s my pleasure. I’m very happy you enjoyed it. Thank you for watching
My brother in law is a jet mechanic for AA in Tulsa. Nice video work and perfect audio. Amazing piece of engineering!
Thank you so much. I’ll be in Tulsa in early March, I might see him.
This is such an awesome overview! I consider myself fairly knowledgeable and I learned so much from this, so thanks.
Glad it was helpful! And thank you for being here and watching 👍
Man that’s so cool. Thanks for sharing. My best friend was a turbine engine mechanic in the air force and always tried explaining things to me but it’s much easier to understand when you can see it. 👍🏻
im happy you enjoyed it and learned
Great video. So much information. 👍🏻
Many thanks 🙏
What a great job explaining something we passengers would never see. Excellent video and explanation.
I’m very happy you enjoyed it
It's obvious that you love your job. It's really good to see AMTs which have a passion for the trade, rather than treating it as just another job. I'm at 29 years as an aircraft mechanic. 23 years USAF, and 6 as an AMT. I absolutely love my job. The 777F is one of my favorites to work on. MD-11 is my first.
It’s definitely one of those jobs that you have to truly love to appreciate, you also have to have a deep passion for Aviation. The 777 is a wonderful aircraft, the 727 was my first.
GE employee here who helps manufacture these bad boys. Cool to see how you (our customer) deals with them on the daily basis!
Thank you for building an incredible engine. i take great pleasure working on it on a daily basis
I could watch this kind of video for long periods of time. Don't ever feel the need to rush.
thank you
Thank you for your PASSION, it’s great to learn from everyone’s trade skills.
My pleasure!
That was so interesting to see what is hidden beneath those cowlings. Keep those videos coming.
Thanks, will do!
Brilliant insight into these fascinating works of art, excellent commentary Thank you Stig.
Glad you enjoyed it. Thank you for watching.
Absolutely fantastic video! Thank you for the opportunity to see inside.
Glad you enjoyed it!
Utterly incredible!
Love the "long" videos
Thank you for sharing
Glad you like them!
thank you for showing us around all the inner workings.
my pleasure
Brother, what a fantastic channel. Only just found you now, so candid and real. Brilliant mate 🙌🏼
Pleasure to have you here. Enjoy the adventures
In my opinion, this engine and others like it are the epitome of engineering. So many components working exactly like they are supposed to with tight tolerances for thousands of hours in the worst conditions. Just amazing!
I agree with you 100%
Absolutely brilliant.
Thanks for your hi level technical video excellently shot. Loved it.
I’m happy you enjoyed it. I appreciate you watching
I worked at LHR for many years and when I saw United do its inaugural flight with the RR trent is was huge, and on the same day BA had the GE 90, BOTH ETOPS going over the Atlantic to Kennedy probably. It was stunning hearing them spool up. The idle on these engines were high and would cause the A/C to creep at a speed without throttle.
Super excellent & super wonderful mechanical & electrical engineering technology which produces GE 90 engines #❤️❤️ 👍🇵🇰
Well said
One of the best things I've seen on TH-cam... thank you!
You're very welcome!
Beautiful! Just beautiful and well explained! Thank you.
Thank you very much. Glad you enjoyed it
Thank you so much !
I really enjoyed this “tour” !
I bet you are an instructor too. Very nice didactics !!! Take care .
Thank you very much! and im far from an instructor, just a regular mechanic
Thank you. Very interesting to me. I’ve worked on cars to big trucks and equipment for 39 years but know almost nothing about aviation
I’m glad you enjoyed it
Thank you so much for this @StigAviation . Huge engines like this 115B and the Trent 900 are the reason I want to study aerospace engineering or aircraft maintenance. I would love to go into aerospace but I can't due to lack of funds.I've been trying for 10 years now, since I got out of high school.Your videos are among the things that keep my flames of passion burning. KEEP IT UP SIR!!!.
Thank you for the info about this fascinating engine. Now that you are making full screen TH-cam videos I hope you will consider making another full screen video about this huge engine. And longer videos are welcome, the content certainly justifies it.
I have been making very long videos lately, and with proper filming of landscape, if you have time check it out Carl. And thank you for watching.
Amazing video. Thanks for sharing.
Thanks for watching!
Please keep them coming, I'm learning a lot from you guys 🙏🏾
You got it! 👍
Men behind the machines are unsung heros
One day the world will see that.
Incredible, the stigster shows us a masterpiece of human endeavor.
It’s an absolutely incredible feat of engineering
Thank you for taking the time to produce these informative videos, I have loved aircraft since I was young. I subscribe to plane and pilot magazine even though I'm a fifty year old truck driver now.
I’m happy you are enjoying aviation and thank you for all your hard work sir. Truck drivers are the backbone of nations.
O yes, a lot of passangers even do not know about Maintenance staff and what they do, but you telling them that we exist, (above 40 years aviation experience) good job.
That’s why I call us “the ghosts of aviation “. You’ll never see us… but we are what make the metal really move. 👍
Wow, amazing, my soul delights in your channel,my mind is overcome by human knowledge,gracias.
Wow, thank you
Just INSANE engineering wow 👍👍👍🔥🔥🔥
Perfectly said 👌
So cool. I work on IDG’s all day but I’ve never seen it on an aircraft. I’m based in Miami and I work at a place called summit. All I do is disassembling inspect and reassemble and test IDG’s all day.
Frank what’s really cool is that I have seen an IDG disassembled only one time in my life, and that thing is absolutely incredible
@@StigAviation it really is. Just taking it apart is amazing. Thanks for replying dude. Awesome. I’m actually starting a program to become a pilot so I’ll be putting the tools down soon. Maybe one day I’ll run into you. Love the channel and the content stig. Awesome stuff as always.
This was a great tour of the engine. Thank you!
Glad you enjoyed it!
What a good and informative video.
Glad you enjoyed it
When I was driving OTR long haul on I-5 between Seattle and Portland I’d see special semi - trailer combinations hauling those GE 90’s to Everett. They are big. A lot of overpasses on I-5 in Washington state where built in the late 50’s when they originally built the interstate system. Those engines would barely fit under them. They had convoy vehicles with special strike antennas in front of the semi’s. As for being a OTR truck driver hauling Jet engines is a good gig , that’s all these guys do is haul Jet engines.
Yup. I seen that too. Fun fact.. most hazmat components have to be hauled by truck. They can put it on aircraft. We have gotten many deliveries like that to LAX.
Very good video, thanks. I'm allways fascinated by these engines when I fly on B777 300ER towards Caribbean. A master piece of engineering and a huge power.
Couldn't agree more!
Amazing and beautiful🤙🌅✈️
almost lol but within limits
I worked on c-17s in the Air Force as a 7level technician (engines was my shred) but I was also a 5 level crew chief. Everything you explained was true. EXCEPT those automatic buttons for the TR doors and accessory doors. We had to get stands and hydraulic hand pumps for the TR door’s because the Air Force thought it would be funny to watch us use those pumps all while telling us to hurry because said jet was to block out soon. So… lol.
I assume on military jets they try to make it as simple as possible on the systems. But our narrow body jets with the smaller engines are like that too. Manually hand pumps to open the TR cowlings.
Excellent video. Everything is fine. My congratulations.
Thank you very much!
Those GE90 engines are amazing pieces of machinery. I wish I could see one up close. An airplane mechanic at LAX told me the basic concept of the jet engine : air is sucked in, then it’s compressed, and then fuel is added, and then it’s blown out the back. But my question is this: why do the engines sound so loud? Their thundering roar also amazes me. Jets taking off from San Francisco fly over my house at about 25,000 feet and even at that distance I can hear the onions roar. Wow are they so loud.?
The good old concept, with a bit of comedy, suck, squeeze, bang, blow 😅 obviously, there’s a lot more involved. But the reason they make that sound is because you have a lot of compressed air being ignited, it’s a very large engine it’s gonna make large sound.
Excellent video. Thanks 👍 Brother. Good bless you.
Thanks, you too!
What amazes me the most is the cowling ring and how it doesn't bump against the fan blades. There's what, 5 mm between the two? With all the bumps those planes take, it's amazing the blades don't grind!
It’s perfectly engineered, it’s quite amazing even I get shocked at some of the tight tolerances
Appreciated your service in fellow human safety....God bless You 🙏🙏
Thank you so much 😊
Only recently discovered you Stig , absolutely love your approach .. Informative and educational. I'm a light vehicle tech but wishes I'd gone into aviation doing your stuff . "subbed and belled" 😁👌
Thank you very much Mike. A pleasure having you here. Thank you for the watching.
Thank you for your service! 🙏 With your skills, we get to fly in this beast's safe belly.
I appreciate that!
Very good and informative video 📹
Glad you enjoyed it
