Abstract:The measured variations in burning pressure with time for a heterogeneous solid propellant with added ferromagnetic particles of size 0.2-0.5 mm are presented. The laboratory tests were conducted with and without an applied external magnetic field generated by a neodymium magnet. The magnetic induction inside the ballistic chamber in which the experiments were performed, was calculated. Variations in the recorded operating pressure reached up to 60%. At the same time it was noticed that the linear burning rate increased by 7%.
