| Popis: | The paper describes a question of measuring the maximum pressure of powder gases in the barrel of 120 mm L44 Leopard 2A4 tank gun in the Institute’s testing position which, in opposite to the thank, deploys two independent methods of simultaneous measurement. The paper compares the measurement methods, the first based on placement of crushing devices directly inside the tested cartridge, and the second on deployment of a piezoelectric sensor assembled into a specially made seat in the gun’s cartridge chamber. Preparation of testing equipment and permanent monitoring of its technical condition to secure the accuracy of measurement of maximum pressure for powder gases is described. Aggregated test results of 120 mm ammunition are used to compare the deployed methods regarding (among others) the repeatability of results, reliability of the measuring equipment, and the time needed to its preparation and to the measurement at the gun site. Recommending of only one from described methods for the application may be difficult as there are many factors affecting the measurement of the maximal pressure of powder gases in the barrel bore. |
