The Aeroprediction Code is a semi-empirical computer program that estimates the aerodynamics of weapons over the Mach number range 0 to 20, angle of attack range 0 to 90 degrees, and for configurations that have various cross sectional body shapes. Weapons considered include projectiles, missiles, bombs, rockets and mortars. Both static and dynamic aerodynamics are predicted with good accuracy.[citation needed] The code also predicts the trajectory of the weapon using the aerodynamics predicted by the code.
