The Effect of Manufacturing Quality on Rocket Precision

The effect of manufacturing quality on rocket impact point dispersion is analyzed. approach presented here applies to any type rocket. Here, demonstrated for the unguided rocket, and by simulating four typical errors: erroneously manufactured warhead, misalignment between warhead engine chamber, asymmetrically installed propellant, error in nozzle manufacturing. A new methodology proposed, which combines a 3D CAD model asymmetrical projectile (due errors) improved Six-degrees-of-freedom (6DOF) its flight into comprehensive Monte-Carlo simulation. In that way, trajectory correlated directly imperfection process. Three levels are simulated (low, standard, high quality), each analyzed errors depends chosen quality. results show how important it impose highest manufacturing, if this condition not met, reveal strict tolerances applied other steps process can compensate consequential drop precision.
