when you press I buton on some planes,its smoke effect.But I wonder what it is in real airplanes,how that snmoke effect creates,do you know or do you have some linke to show,I realy want to know how*?

Smoke is usually produced by introducing diesel oil into the exhaust. The colour can be changed by mixing dye with the diesel. This works on both piston & jet engined aircraft. http://www.raf.mod.uk/reds/dyeteam.html

Some display aircraft are fitted with special smoke generators. These are like small gas turbine engines & work on the same principle.

disel oli into exhaust,but hoe exhaust are in wings,some airplane have it on wings some on tail,like extra 300s,and some jets,I still dont undesrstand,and will they lose thair diesel oil durinf smoke effects...

Here's a shot of the Sukhoi Su 26 taken at a recent air display. Note the smoke is coming from the engine exhaust stubs.


Now a

what that dieseil oli use for in airplane,and is it some extra oli only for  smoke or it is use in flight for flying and will somthing ha

The smoke system is completely separate & only fitted to display aircraft. It has no effect on the performance of the aircraft. Read the article from the link I posted in my first reply.

are you a real pilot of smoke effected aircrafts

No but I have worked on the smoke systems. I've also been to a lot of air displays over the years.

I think that nowdays they use vegetable oil or other non-petroleum oil due to environmental concerns. At least they did so at the Indianpolis airshow.

Not sure what the military display teams use. It says diesel oil on the Red Arrows site. I've heard they use baby oil on the smaller piston-engined types.
