Content available Regarding of antifire ballistic system
EN
In this paper it is presented the main aspects concerning of utility, designing and realization of antifire ballistic system. This system is designated for extinguishing of fire in closed areas with difficult accessible positions, acting at distances of 10 to 450 m and different elevations. The system is a recoil ballistic system and can be used individually or embarked on auto vehicles and helicopters. In paper is presented ballistic designing of such as system, too. The system was realized and in present is during of testing.
EN
In this paper is presented a testing method of propulsion systems on simile micro models. In order to calculate and design a micro engine simile with a real rocket engine, physical and geometrical relations where deduced. On the base of experimental data measured after testing of simile micro engine, can be establish the ballistic parameters of real rocket engine.
