THE APPLICATION RESEARCH ON THE LOW TEMPERATURE SENSITIVITY CHARGE OF NITRAMINE PROPELLANT

Accroding to the principle of low temperature sensitivity charge(LTSC), the application test of LTSC of nitramine propellant in the large middle caliber gun was analysed. By the test of the burning characteristic of nitramine propellant, it was found that sent the pressure and burning rate curve varied almost linearly. At the same time, the low temperature mechanics performances of the nitramine propellant with the drop hammer hit method, showed that the low temperature mechanics performance of the nitramine propellant needed improvement. At last, accroding to the interior ballistic results of velocity and most chamber pressure by use of LTSC of nitramine propellant and the results of gun ablation. It is proved that the applicasion of LTSC of nitramine propellant in large middle caliber gun is feasible.
