Abstract

To analysis the electrostatic risk in the mixing process of typical propellants, the distribution of the electrostatic field inside the cylinders was investigated. The maximum charge quantity (−1.895 μC kg⁻¹) and relative dielectric constant (1.88) of 11/7 propellant were obtained through experiments. Based on Ansoft Maxwell electrostatic field numerical analysis, the electrostatic field intensity and potential distribution inside the cylinder were obtained. The maximum electrostatic field intensity and potential of 11/7 propellant increased with the propellant height. When the propellant height increased to 290 mm with a diameter of 300 mm, the maximum field intensity at the bottom was 15.1 MV/m.
