APPLICATION OF THE PRINC-IPLE OF THE HIGH/LOW PRESSURE CHAMBER TO THE OPTIMIZATION OF THE FEED DRIVE IN AUTOMATIC GRENADE LAUNCHERS
Jaramaz Slobodan Micković Dejan
Theoretical and experimental investigations were carried out in order to opti-mize drive and construction parameters of a particular automatic grenade launcher. Special attention was paid to the modelling of the flow of the two-phase mixture of powder gases and unburnt powder from the high pressure chamber into the low pressure chamber, as well as to the expansion of powder combustion into the low pressure chamber and the launcher tube. The gradient pressure equation was developed to define the distribution of powder gases pressure in the low pressure chamber and the tube…
