Compressors - Turbine Engines: A Closer Look

Lets look around inside the compressors of a few different turbine engines. How does it all fit together, where does the air go, and how does it work ?

I have filed and/or replaced countless numbers of compressor blades on the J79 during my air force tour of duty. bird strike compressors were nasty to repair/replace because of the odor of "cooked" bird meat throughout the motor. I once found the impression of Abraham Lincoln on a first stage compressor blade, one of the flight line crew forgot to empty his pockets before intake inspection of the RF4C Phantom, his nickel cost a half million dollars in motor damage.

For an engineering hobbyist and aspiring aerospace engineer looking to design my own turbine engines, this channel has been such a wonderful resource. Have car mechanics in my family and they told me there are few better places to learn how something works than from the people that maintain and repair them. Engineering literature has taught me a lot about how jet engines work, but this channel has showed me a lot of the practical considerations I need to make if I were to actually build one.

Thank you for these awesome videos.

4:18 I didn't know the blades supposed to be loose. Learned something today. Thanks!

This is incredibly educational. Thanks so much for sharing this awesome content.

As a student pilot this video is pure gold for me. Thanks.

[HarryLHernandez]

Hands down, one of the best videos I’ve seen today

This was awesome and that cutaway is awesome. I have always been fascinated by jet engines and have never had the opportunity to see such cool stuff. Thanks for uploading these!

Was reading a favored financial blog and someone posted a link that brought me here. What a cool surprise. Video length 7:47 ((: I forwarded your J79-Turbine Engines: A closer look vid to my 92 year old ex-Lockheed engineer Uncle Bill. So now you have two new devout readers. You Rock. Cheers ~Valerie~

I wonder if it's 7:47 long on purpose

A gum wrapper would not damage a turbofan at all. Nor one of these turbojets. But it would be turned to dust, not just shredded.
One of the major advantages of turbofans is they tend to shunt debris through the bypass duct..."bypassing" the core. Overall this makes the engine very resistant to damage by birds and such. A bag of marbles going into a GE90? it would be very unhappy, but it would keep running. If one marble went into the core of the same engine, it would be unable to make any power.

Ich kam mir vor auf einer Zeitgeist. Zurück in meine Ausbildung 1980. Das waren diese Engines state of the Art JT8 d7 / d15 etc.
Sehr schön und plastisch erklärt.
Like a trainer👏👏👍👍😎

Thank you very much for making this video. 12 years later and it just saved me from lots of wrong imaginations about how turbines and compressors work, God bless you.

The genius is the guy who designs the size and angles of those blades.

Yu “filled in the holes” for me in more ways than one by this lifesize sample - it just clicked and added practical education to the theory and diagrams I have been learning from! Thank you !

I have been watching your videos on YouTube for quite a while. I have learned so much about how a jet engine functions. From compressors to afterburners. From lubrication to working air. Thank you so much for putting the hard work, on "your" spare time to create these videos. I had the opportunity to go into the military to become a jet engine technician, but I was young and dumb and now I realized that I missed an opportunity of a lifetime that I could enjoy. Agent Jay Z, your an amazing guy who goes out of his way to share his passion for jet engines to educate people who wants to know and learn from this. I can't say enough, but thank you again! Canada Rocks!

The way each stage is clocked in relation to the one behind it is absolutely mesmerizing.

I used to build the engine core for CF6 compressors. Learned real quick watch your fingers while installing the case halves. A slight turn on the rotor split my nail while setting up for a wax check. To check blade and stator clearances. After 35 years working on aircraft and thier engines I still have all my fingers!

Thanks for the trip down memory lane. I was in the National Guard 40 years ago, worked on CH 47 and UH1 helicopter engines. I blended and polished quite a few blades that suffered FOD. (Foreign object damage). Blades that could not be fixed were smashed with a hammer to prevent them from finding their way into our spare parts streams. Various use once parts From the aircraft were also given the hammer treatment. This would prevent the unscrupulous parts suppliers from performing unauthorized repairs to critical parts.I understand even now counterfeit parts can be a problem in the aviation industries.

[frankievassallo]

I thank you for this video. Because I understand how it works. When learning something, books give me an idea on how things work but not at this level. Thank you 🙏

Fantastic video. I teach new Crew Chiefs in the Air Force about the F-16's engine (both Pratt and GE), and this video will help me describe the stators within the high pressure compression section much better.
