Abstract

This paper aims at the energy characteristics for four propellants: HTPB/AP、AP/NC、LS/NC、LS/SQ-2 through the thermodynamic calculations. Thermal degradation due to different proportion of the LS / NC formula and different proportion of the LS / SQ-2 propellants is studied by DSC and TG. Ignition tests due to different proportion of the propellants aim to screen out the best propellant whose energy and heat sensitivity meet the requirements for micro-thrusters. The resulting thrusts and impulses by experiments for the quality of different charge micro were compared with numerical simulations. This study on the thermal behavior therefore provides promising applications of solid propellants for rocket propulsion systems..
