ANALYSIS OF HEAT LOSSES IN SMALL-SIZE SYSTEM OF UNDERWATER SHOOTING BASED ON SOLID-PROPELLANT GAS GENERATOR
RPA Iskra jointly with RIPM (as regards to solid propellant charge) developed and studied small-size system for shooting a container into water which is based on solid-propellant gas generator. There was emphasized the importance of heat losses correct calculations for solving problems of internal ballistics. There were revealed specific design sections significant for heat exchange. For simulation of heat processes in a standard product there was designed and manufactured a multichamber gas generator as an experimental plant. There were carried out several charge firing tests in experimental plant at RIPM facilities. By analysis of experimental internal ballistic parameters there was determined heat loss coefficient which was used for standard product manufacture. Standard product optimization approved correctness of heat losses determination in experimental plant.
