A mathematical-physical model of the hypersonic anti-tank kinetic subcalibre projectile for 120 mm munition was built. Computer simulations of the projectile flight were performed for any angle of shooting, from 0° to 90°. Trajectories of projectile flights were determined considering all angles of shooting. Theoretical calculations were verified by experimental measurement of the projectile velocity in time while shooting on a test range. Some conclusions with regard to safety during hypersonic projectile shooting on the test range were formulated.

Abstract.A mathematical-physical model of a supersonic missile was built, taking into account the mass and inertia properties. The model was implemented in the MathCAD14 simulation program. A numerical analysis of the missile ballistics was conducted and basic parameters were determined: range, altitude, velocity and acceleration, which enabled a test range program for manufactured missile models to be drawn up. Initial flight tests of missiles were carried out at the test range. Satisfactory accordance of experimental and theoretical dynamic parameters of the missile under study was obtained.

The paper presents a specification and performance characteristics of a computer software application developed for rocket design engineering. The methodology for the determination of aerodynamic characteristics by the software application is based on the Chernabrovkin-Lebyadyev’s experimental and theoretical method. The computer simulation results presented in the paper were generated for two types of 122-mm calibre rockets, M-21OF Grad and M-21FHE Feniks. The simulation results were verified with the results produced using other calculation methods.
