Abstract: The effect of air pressure (0.01–0.3 MPa) on the detonatability of an aerosuspension of secondary explosive particles at a low mean volume density of the explosive (0.14–1.28 mg/cm$^3$) is experimentally studied. The structure and basic parameters of detonation depending on the explosive density and initial gas pressure are determined, and the mechanism of low-velocity detonation propagation in explosive aerosuspensions is revealed. The lower concentration limits of detonation at different initial gas pressures are found.
Keywords: secondary explosives, detonation limits, detonation mechanism, critical density of an explosive aerosuspension, detonation velocity.
