Grean explanation? So Can I ask some questions? 1. So the blade pic above is it the active spinning turbine or the other one that doesn't spin? 2. what material is go through these holes inside the turbine? Air or liquid? 3. Then if it was air, is it from the bleed line from the compressor or additional cooling pump? 4. Is there also bled air that skipped combustion stage then sent forward to mix with exhaust gasses to decrease it's temp
1. The pic is of the rotating turbine blades. 2. Air is passing through the holes. 3. The air is taken from the compressor 4. Only approximately 20% of the air that is ingested by the engine is used for combustion, the rest is used for cooling.
@@RoddyMcNamee ok thanks bro, it's really help me out. But how did a hole really that small on a thousands of rpms spinning turbine rotor could let air in?
@@RoddyMcNamee no no, that's not what I meant. You know the blade is rotating, then my question is how the cooling air is coming in inside the holes from outer frame? Is it actually possible for air to get inside a fast rotating blades?
Good video, thank you for explaining.
Which one is more efficient here?
thank you !!!, how the air channels are made ?
ceramic cores that the metal is cast around then leached out with potassium hydroxide or sodium hydroxide after casting.
why use individual blades rather than one blisk?

@@abdulhakim.a1640 have a look at this th-cam.com/video/ff6YVzg2YqM/w-d-xo.html

@@RoddyMcNamee also the inlet holes was just so tiny
thanks for explaining. Can you share your source?
Rolls Royce, "The Jet Engine", 5th and 6th editions.
The day we start doing that on rocket engine turbines we can probably lift a skyscraper tall rocket.
What the program are you using to make modeling and try to simulation?
PowerPoint.
So 😎
The CCP approves this message.
😂😂😂
there is a better way.
Why u talk like this
