No words can tell how much I am appreciated for these videos, all thanks for the efforts.

Fun fact: The sectional bearings are not all made of the same metals. This is so when oil analysis testing is done for monitoring the bearings, if there are bearing metals present in the oil, the individual bearings can be identified for wear.

واقعا هر چند سال یکبار مهندسان توربین،،تازه میفهمند بعضی از قطعات انقدر ها که بهش اهمیت داده شده،،،فایده و کاریی چندانی نداشتند وفقط سازه را پیچیده وسنگین میکرد وبر عکس این موضوع نیز صادق است ،،به چیزهایی که تا قبله این توجه نداشتن درست در جایه به جا قرار بگیره چقدر کار ،،را مفید ومختصر تر میکنه ،،گزشت زمان وحوادت تلخ بهت میاموزه،،،حداقل اشتباهات بزرگ که مقابل چشمت بود ونفهمیدی،،را دیگه نداشته باشی.با ارزوی پیروزی هرچه بیشتر صنعت هوایی،،سپاس گذارتونیم♥️♥️

incredible how tiny the oil reservoir is on such a huge engine. the large trents seem to have a lot of blowby, i assume from having the smallest possible reservoir as well. thank you for these most amazing videos/animations. definitely the best! very clear and easy to understand! :)

Fantastic video. Even not been a pilot I love technology and the science behind every machine and specially airplane. After watching these videos every time I fly my brain can see the harmony of all these components working together to make an airplane to fly in the sky and not only that but also flying for long hours connecting one country to another.

I worked for GE machining the front fan hub which the fan blades are installed. I also machined the stage 1 & stage 2 high pressure turbine discs.

Keep up the good work please! I'm a big fan of the GE-90 and I'm a nerd that spends hour simulating on the T7 using PMDG magnificent airplane. This just explains the nuts and bolts of how this engineering masterpiece works!

Information with Background music gives goosebumps 🛐🙌 🔥🔥

[nikoahoenk]

Your video is amazing. Give us aditional knowledge. Thank you!

[sursadhnayoutube]

These are the productions of intelligent minds

[Tpr_]

I know some of this stuff but I love the animations such that I always watch

[tk]

Just another great animation and lesson. Really and highly appreciated. Thanks for the effort ! Keep doing.

[robertedwards]

Amazing technology on how a jet engine works and how it is protected. Amazing technology on how these videos were made and how they are watched . Thx.

[imrankhan-ivsn]

Amazing 👏 never seen such information videos ever. Beautifully animated and explanation.
Hats off. Keep it up!

[theriddleman]

Great video with really good explanation. Eagerly waiting for the final episode of the series. Could you also do a series on the A320 and its systems.

[himmetramthakur]

Thanks for sand video . अब part 5 की वीडियो भेजो ge90 ge9x Jet engine

[OneAndOnlyMe]

An excellent series of videos. Thank you for these! I know so much more about what is happening when I'm on a plane now!

[anuppatel]

Excellent series of videos! Please keep up the good work.

[Nyck]

Amazing videos. I love how these engines work.

4:30 interesting, they have core compartment cooling, and also, as shown earlier in the series, cooling systems for turbine clearance control... Kind of odd that they are not one and the same
