I'm currently taking an aeronautical engineering course in school. For an upcoming project, we're going to build balsa toss gliders and we have to design our own wings. The program we're using (Aery32) provides information about how the model will fly, including CoD, AoA, and glide angle. I already know that using long, tapered wings will provide the most efficiency, however, to further optimize the design, I need to know which item I should minimize- AoA or glide angle. Obviously in a perfect world I would do both however I don't have a large amount of time. To summarize- I'd like to know if reducing the angle of attack or decreasing the glide angle will provide a further glide.
