Resumo
The paper presents an approximate model for determining the shape of the formed hot spot on the surface of burning gunpowder at different pressures of gas medium. It was found that with increasing pressure, the geometric dimensions of the hot spot decrease. The burning hearth appears in extinguishment or in nonstationary mode. Apparently, if the dimensions of the hot spot along the surface of the powder and along its height are connected by an “elliptical” connection then its geometric shape is the closest to the experimental shape.
