While investigating dynamic properties of aerial bombs, both the analytical and experimental outcome often find their applications. Analysis of how a series of changes in flight parameters affect flight dynamics is probably one of the most essential efforts throughout this study. Numerical solutions of equations of motion deliver no information on the effect of changes in the aerial bomb’s design parameters on flight characteristics thereof. Therefore, the theory of sensitivity has been used in the paper to investigate the effect(s) of external disturbances, drop/release conditions and technical parameters on the aerial bomb’s range and flight path. Among other, the elements of the theory of sensitivity, equations of motion, numerical analysis of sensitivity of the bomb-describing mathematical model to changes in some selected parameters, numerical analysis of sensitivity of the bomb-describing mathematical model to changes in some selected parameters, analysis of the effect of changes in drop/release conditions on the aerial bomb’s flight path, analysis of the effect of changes in engineering (design) parameters of the aerial bomb on the trajectory thereof, effect of drop conditions on the aerial bomb’s range, effect of drop conditions on the side deflection of the aerial bomb’s trajectory are presented in the paper.
