Select paper bullets without a shell as the application background , analysis of the propellant system performance constraints were low vulnerability propellant based formulation design, processing conditions and properties. For basic formula has burning rate pressure exponent greater than 1 , and poor mechanical performance characteristics , its design optimization of the formulation and process conditions to explore ; using closed bomb , DSC and other tests studied by means of particle size , such as ammonium nitrate , nitramine crystal shape , nitrate amine content of different plasticizers on the thermal decomposition properties ; while , through the propellant in the development , production, storage, transport and may be encountered in actual battlefield accident analysis , classification , combined actually , chose to target heat resistance as an evaluation laboratory vulnerability assessment method , using this method for the design of propellant heat resistance test was carried out to study the binder component , plasticizers, nitrocellulose content and RDX particle size and other factors on the impact of heat resistance . The results show that the propellant has excellent heat resistance.
