Abstract
The paper presents new experimental results on the dynamics of the cloud of explosive combustion products of the mechanoactivated composition Al/CuO. The parameters of the cloud of combustion products depending on the mass of the mixture were determined using the methods of high-speed photoregistration, pyrometric measurements, and photovoltaic and electrocontact sensors. Various methods of ignition and formation of the product flow are considered. Optimal conditions for the formation of a torch for ignition of combustible gas–air mixtures have been determined.
