Jet Engine Irises - How to make?

[TMortan]

Its an exhaust nozzle

Not a jet expert but i know on the F-22 its also a directional nozzle (vector thrust) providing more agility by controlling the direction of thrust.

Cool, I'll do some searching. It's amazing how hard it is to search for something when you don't know what it's called :)

Thanks,

Thanks to some help from Digital_Crystal, I've worked out a rough, functioning solution. Now I just need to remake it with more detail... !!!

search for GE-110 engine, the nozzle of some block30 and up F16. you will notice how each 'petal' is designed in order to let the previous one slide over it and itself slide over the next one. I had a maxfile of it at home maybe ill post it later on.

This is the best photo I've found so far:

Can't see much detail on the inner petals, but the large outer petals make sense.

If you have a max file you could post, that would be great. Or if you have some good references, I'd appeciate tha as well.

when this is open reducced velocity of air scape and the speed of the machin,closed make the air push strong and accelerate the machine.

sorry for my english.

These things are also often refered to as "turkey feathers".

Kinda like fst4ry said:

A small diameter outlet = low volume, high velocity exhaust = lower thrust but high aircraft speed.

A large diameter outlet -> high volume, low velocity exhaust = high thrust but low aircraft speed, typically used for take-off and other low speed, high thrust situations.

Hope this helps
