摘要

In this study, we evaluated effect of Aluminum (Al) particles for combustion mechanism of Ammonium Nitrate (AN) composite propellant. In the result of the combustion experiments, the burning rate of AN composite propellants increased with increasing concentration of Al particles. Aluminum particles do not ignite and combust at solid phase including burning surface of AN composite propellants from the result of the experiment of using Differential Scanning Calorimeter (DSC) and temperature history. Aluminum particles ignite and combust in the gas phase of AN composite propellants from the result of temperature history. Temperature gradients of AN composite propellants increase with increasing concentration of Al particles. Reaction heat in gas phase increase with increasing concentration of Al particles from analysis result of temperature history. Therefore, temperature gradients increase with increasing heat of reaction in gas phase.
