External ballistic of volcanic explosions [PDF]

open access: yesBulletin Volcanologique, 1983
In order to determine the kinetic energy of an explosion it is necessary to know the initial velocities of ejected fragments. Calculations of initial velocities made earlier with few exceptions did not take into account the resistance of the air and therefore, greatly underestimated the initial velocities, and consequently the energy of the explosions.

Electronic Shooting Simulator Family "STrIzh": Implementation Levels and Free Software Structure

open access: yesПриборы и методы измерений, 2023
Development of rifle electronic simulators (i.e. for hand weapons and not using ammunition) is an important task, since the production of any type of small arms according to regulatory documents also requires the production of a simulator to instill ...

THE ACCURACY OF NUMERICAL SIMULATION OF HUROKET EXTERNAL BALLISTICS BASED ON THE EXAMPLE OF THE M-21OF ROCKET

open access: yesProceedings, 2023
Using the example of the M-21OF rocket, the deviations of the results obtained by the software developed for solving the equations of external ballistics of rockets by computational methods, are investigated.

Study of the temporal distribution density of the shot sheaf span to create a simulation model of the optical sensor signal

open access: yesКомпьютерная оптика, 2021
When studying the space path of a cloud of pellets from a shotgun and evaluating its parameters, it is advisable to have a simulation model of the optical sensor signal when a shot sheaf crosses the light screen.

New Cartridge Design for Assault Rifle [PDF]

open access: yesProblemy Mechatroniki, 2020
The article deals with the possible design of a new cartridge for an automatic assault rifle. This hypothetical design is based on the analysis of five automatic assault rifle cartridges which are currently used in armies: 7.62×51 mm NATO, 7.62×39 mm M ...
