Hello, My project is to design a new type of flying RC toy, and since i am not an engineer and I don't know aerodynanic well, I am trying to craft some kind of aerodynamic simulator on my computer, then run some genetic programming to design from scratch any kind of small aircraft capable to fly in the simulated environnement. Ok, that's not clear... I mean: -First, I would try to get any flight simulation software accurate enough to test a new virtual aircraft design (the kind than could have wings and propellers of any shape, in any configuration); -Then run a search algorithm, certainly some form of genetic computing, to evolve a population of flying stuff. The simulation would be used to evaluate the candidates' flying abilities. -Finally, make some blueprints from the best fit evolved critter. Since i'm all but aerodynamic saavy, I'm stuck on the problem of the simulation. Any premade open-source stuff would be perfect, but if i'm going to do the simulator myself, what is the fields i'm the most likely to have to study? Most important, do you have any suggestion for the design of the simulator or any part of my project?
