The article describes a model for calculating external ballistics in the full three-
dimensional formulation in the approximation of the dynamics of a material point. Math-
ematical modeling of the grenade hitting the target was carried out by the method of sta-
tistical tests under variations of shooting external conditions. We estimated a probability
of grenade hitting the frontal projection of the tank in different modes of shooting from
grenade launcher system. It is shown that probability of grenade hitting the target in-
creases significantly when using a jet engine with a system of autoregulation of thrust
characteristics.
Keywords: variation of initial velocity, autoregulation of thrust, pulse engine, external
ballistics, demolition of lateral wind, error of weapons aiming, , error of weapons orien-
tation, technical scattering, probability of hitting.
