Spark transfer in forest fires and their localization using aviation

The results of modelling of spark transfer as one of the most powerful factors influencing forest fire propagation are discussed in the paper. It is shown that this process depends on many factors such as the type and intensity of the fire, characteristics of forest vegetation, wind speed, size, mass and shape of burning particles, duration of their burning and terrain. The accuracy of the description of this process by mathematical methods depends on the degree of consideration of various factors affecting the transfer of burning particles. The developed mathematical models and the techniques created on their basis make it possible to assess the range of transport of burning particles and predict the risks of the occurrence and spread of fire including affecting settlements and objects. In particular, the obtained numerical values of the casting range of burning elements in forest fires allow correct determination of the size of the barrier strips near settlements and objects located in forests.
