Propellant pyrotechnic mixtures based on polytetrafluoroethylene (PTFE) as an oxidant represent a perspective structure of the rocket fuel ignition. In this paper the results of research are presented with characteristics of combustion for different structures based on PTFE as an oxidant and B, Al and Ti as a fuel. By changing the content of the components and their granulation, a myriad of structures is tested along with their characteristics presented in the paper. The possibilities for further researches of pyrotechnic mixtures based on PTFE as an oxidant, are enabled from this paper. It is determined that the characteristics of the mixtures based on Al/PTFE/viton A (Viton A) can be successfully applied with the ignition of certain types of rocket fuels.

Key words: pyrotechnic mixture, propellant mixture, polytetrafluoroethylene, ignition, rocket fuel, burning rate, burning pressure, burning thrust, thermodynamic potential.
