Influence of energetic characteristics of double-base propellants on internal-ballistics parameters (original) (raw)

Solid propellant rocket motors for shoulder launched infantry weapon systems are charac-terized by short working time, high combustion pressure and large range of designer solu-tions for rocket motor structure and geometry of propellant charge. Internal-ballistics pa-rameters of impulse rocket motors depend on many factors: design of rocket motor struc-ture, shape of propellant charge, type of connection between propellant charge and rocket motor body, type and position of ignition system, type of motor rotation and nozzle(s) de-sign. Considering the fact that these rocket systems should be operative in a broad range of ambient temperatures (from -40°C to +60°C), types of rocket propellant and ignition system play important role. In published literature there are no available models which describes in detail process of design of solid propellant rocket motors and there is very limited number of public references with information regarding types of rocket propellants (double-base or ...
