| Popis: | The article introduces an issue of measuring a negative pressure of powder gases in accordance with STANAG 4493. The negative pressure is obtained from measurements of the maximum pressure of powder gases at the front and the end of cartridge chamber during firing with 120 mm tank ammunition. In connection with the above, a simultaneous use of two piezoelectric sensors, placed in special sockets, is needed on a ballistic stand equipped with 120 mm L44 cannon of Leopard 2A4 tank. The purpose of the measurement is to record the values and curves of pressure allowing a detection of any dangerous phenomena occurring in the cannon's chamber during the shot and determination of the level of negative pressure of powder gases for tested ammunition. Defining the negative pressure value facilitates the construction of the propellant charge and helps to analyze the condition of the cannon cartridge chamber over |
