Electrically Controlled Ignition Performance of LiClO4/PVA/H2O Propellants

What is it about?

Repetitive ignition and thrust adjustment of electrically controlled solid rocket motors require that ECSP achieve multiple ignition, adjustable burning rate, and controllable extinguishing within a specific pressure range. Therefore, it is significant to understand and obtain the conductivity, ignition and combustion mechanism of ECSP under electrical field to realize propellant electrical controllable performance. These mechanisms of LP/PVA-based ECSP can provide effective methods to improve the conductivity of ECSP, reduce the ignition voltage and energy consumption, optimize a high-performance ECSP formula, and provide a basis for the establishment of an ECSP ignition model. The electrochemical performance, high-voltage ignition and burning rate characteristics of the LP/PVA/H2O composite were obtained through experimental research; the mechanisms of ion migration, electrolysis, thermal decomposition, ignition and combustion of LP/PVA-based ECSP were proposed.
