Allison 250-C20
A question for all the techs & mechs....
I am trying to get my head around the toroidal vortex in the can of the jetty engine.
My understanding of a toroidal vortex basically a 'donut' spinning in on itself
(Vortex Ring State being a good example of a toroidal vortex).
So my question is how does the air actually flow within the can, to form this 'cooling buffer' (from what I have read large % of air is actually used for cooling).
I am assuming that toroidal vortex spins outwards with the flame, then back up behind the lining. is this correct?
any tips for novices greatly appreciated
