Measuring-computing complex to monitor changes of the initial velocity of artillery shells

摘要

Measuring and computing system for monitoring the change of the initial velocity artillery shells relates to the field of measuring technology and is designed to control using digital technology changes the initial velocity artillery shells due to temperature and humidity changes propellant charges without test firing artillery ammunition.; Measuring and computing system consists of an artillery munition to the sleeve 1 and the shell 9, the propellant charge 2, a strengthened and normal caps 10, 11 temperature sensor and humidity 3, a rubber cover 4, a digital device 5 for measuring the temperature and humidity of a propellant charge placed in artillery liner, the cable 7 to the temperature sensor and humidity compound digital device, USB-cable 8 and a PC with software to calculate the change in the initial artillery projectile velocity.; For monitoring changes initial velocity projectiles from artillery shells 1 are extracted reinforced and normal closure 10, 11 intended to protect the propellant from moisture environmental exposure and fixing of the propellant charge from movement in the propelling charge between the powder sheaves 2 mounted temperature and humidity sensor 3 , the sleeve 1 is closed with rubber cover 4, sensor 3 via the cable 7 is connected to digital device 5 for removing the temperature and humidity readings after establishing their constant values ​​of the (5 minutes after closing the rubber cover sleeve), information from a digital device 5 passes through the USB-cable 8 to the PC 6, a projectile marking 9 is removed indication of its mass and input to the PC 6, the program [6, 7] on the PC calculates powder characteristics depending on its temperature and humidity, are then calculated and the initial velocity of the projectile muzzle velocity variation with respect to the tabulated value with changes in temperature and humidity of the propellant. 3 yl.
