Mr. Tick,
I noticed under your profile that you are an engineer. I'm an ME myself. There are some pretty good books out there that would answer your questions if you had time. I have a couple of suggestions that would help as long as you have a strong math and fluids background. John Anderson has two great books, one called "Fundamentals of Aerodynamics" and he also has one on aircraft design I just can't remember the name. Those are some pretty thick books and just scratch the surface. I spent a lot of time in them back in college. There are probably better books out there. Wells is on the right track.
