The article considers the process of ignition and development of liquid fuel combustion when it receives macroscopic sources of ignition. Heated dispersed particles of various metals and alloys can be such sources produced as a result of cumulative jet penetration through durable steel wall of finite thickness, and the fuel tank located in a confined space. The main physical factors determining the incendiary effect during the explosion of shaped charges at various stages of their interaction with the fuel tank are revealed. The mechanism of liquid-fuel ignition when heated dispersed particles from different ma- terials get into it is investigated in detail. The dependence of the delay time of liquid fuel combustion on the temperature of metal particles and their mass for various materials is determined. The influence of the temperature of liquid fuel on the efficiency of its ignition is researched. The constructive solutions for cavity units are proposed, which make it possible to increase the effectiveness of the beyond-armor effect of the shaped charges without reducing their armor penetration capability by increasing the incendiary effect.
