Correlation Between Burning Rate and Thermal Decomposition of AP/Al-CMDB Propellants

Abstract

Abstract: The correlation between burning rate and thermal decomposition of AP/Al-CMDB propellants in the pressure range of 1.0~13.0 MPa were studied by a high pressure differential scanning calorimetry (PDSC). The results show that the factors of pressure p and exothermic rate ΔH_d/Δθ must be analyzed respectively in the model of the correlation between burning rate and thermal decomposition of AP/Al-CMDB propellants in the pressure range of 1.0~13.0 MPa, where the formula of the correlation model is u=k_uP^a［ΔHd/Δθ］^b. The calculated results show that there is an error of lower than 2.50% between the theoretical burning rates and the experimental values.
