Process

Collecting my design process into one place

1. Pick wing body airfoil (NACA 4412)
2. Pick wing body aspect ratio (7.5)
3. Pick wing body chord length (c_bar = .1016m) (limited by 3d printer size and practical assembly restraints)
4. Calculate b, S from the two above values
5. Calculate L, D, L/D for V=[1,20] and trim_alpha=[-5,5.5]
6. Choose optimal trim_alpha from above calculations
7. Calculate Lift at trim from main wing body
8. Pick Tail airfoil (NACA 4412)
9. Pick Tail chord length/span length
10. Calculate lift from tail at trim - i_t
