Could someone introduces me a source to learn aerodynamics?
By source do you mean book?
Anderson, intro to flight.
Online, there is NASA's "Beginner's Guide to Aerodynamics"
I can assure you that google-searching this topic will give you many more sources than we could ever give you.
It does help to talk to actual people in the profession though. Unfortunately/fortunately Google just gives you so much information that it may or may not really be helpful. Since the OP doesn't know the difference between the good and the bad, it makes it difficult to choose.
You told my heart's speech.In fact it is for almost a year i'm searching about physics in google and yahoo but i gained no achievement until i came here.
and excuse me.by source i meant online ones.
and thanks pantaz that was just the thing that i wanted
