Aerodynamic solver of BALLISTICeda uses component buildup method to find overall aerodynamic loads acting on a projectile or missile. Aerodynamic characteristics of major components such as wings, body, and tails are calculated by using linear theory and/or slender body theory are summed by considering component specific weighting interference factors. Some semi-empirical formulations based on experimental database may also be utilized.
