ABSTRACT
The problem of accuracy of fire and its impact on weapon effectiveness presents a
major concern of munitions designer. Many factors can be considered to improve the
missile dispersion. Some are related to the missile itself, others are related to the
launcher or the mutual effects between the missile and the launcher. The
environmental launching conditions have a prime impact on the firing accuracy. The
present work introduces simulation and experimental studies dealing with individual
parameters and their influential weights concerning their impact on dispersion of a
finned missile. The effects of the initial firing parameters, namely initial mass, initial
launching angle, initial velocity and location of center of gravity are investigated. For
each case the parameter was varied within certain limits to simulate the production
inaccuracy, or approximations during design and the initial errors that can be
impeded in the launcher and aiming devices. The trajectory was calculated using
PRODAS software and compared with the real flight data. Comparisons of predicted
and experimental results have proven satisfactory matching.
