Abstract: Dependences of the burning rate of powders, solid propellants, and explosives on pressure are analyzed. For this purpose, the coordinates are rotated by an angle whose tangent is equal to the burning rate coefficient in its one-term dependence on pressure. Different versions of approximation are considered, and an expression that best approximates the dependence of burning rate on pressure in the pressure range from zero to infinity is proposed.

Keywords: combustion, burning rate, pressure, approximation.
