Combustor Liners 2 - Turbine Engines : A Closer Look

A look at the second, inner layer of the combustor liners in a J79 jet engine, and how the afterburner is similarly constructed.
I didn't explain as well as I should have that the inner dome is the inside layer "inside" the combustor liner I hold up...

Nice video of flame tubes :)

@FrontSideBus Gaaaack !! That's Rolls Royce terminology !

It's Ok, sometimes I also drive on the left side of the road.. :)

Great video. I didn't know any of this before - I figured they were just flameholders. This better explains what those big heavy parts are doing in there.

Have you guys had a chance to do anything on the Iroquois lately?

@sharrynuk We are worshipping its greatness, but are spending all of our shop time completing customer's work orders...

Finally someone who tells them whats up with the combustor, im sick of those beer can "jet engines". I for my part have to say, the liners are maybe the most important part of a jet engine, it took me 3 different combustor liners before my engine got down to an acceptable Temperature level.

One important thing to add might be, that the liner not only cools the flame, but it holds it in place, without the liner the fuel would burn behind the exhaust nozzle of the engine what would be... pointless

[AgentJayZ]

@XTwina Yeah.. I thought I covered that, but it was a bit quick. Every time you and the other guys notice a detail like that... it makes me try harder. :)

@TheElectricnoob This is an issue that is not open to public discussion. Thank you for your interest in our products. Please pay no attention to any grey, windowless vans parked on your street.

Your videos single handily are the #1 resource on the entire internet for how jet engines work from a non mathematical standpoint. You have done the world a great service.

Great stuff.

It took me about a year to figure this out from 1993 to 1994 (pre-internet).  I used a coffee can for a liner, Folgers.

You Are a Fantastic Teacher!

Thank You!

@AgentJayZ good :D It seems,that there is a lot o demand on basic information about turbines, but do you plan to make more closer videos about things you cant find anywhere ele on the web ? Dont get me wrong, those videos are great, but you have access to the most awesome technology and the people ask for stuff thats explained on wikipedia? Thats wired ^-^

cheers XT
