ximately twice for all considered types of soil and rocky tar-
gets. With the increase in initial velocity, the relative incre-
ment of penetration depth decreases at the fixed mass of
a solid propellant charge. It is caused by the decrease in a
relative share of chemical energy of rocket propellant com-
bustion in comparison with initial kinetic energy of the pro-
jectile. For projectile velocity of 1000 m/s and a reserve of
rocket propellant in 20 % of projectile weight, the penetration
depth increment reaches 60 % for dense soil, 45 % for low-
strength rock and 40 % for high-strength rock at a rational
choice of jet impulse parameters
