    This paper presents a method for determining the ignition delay time of condensed systems when exposed to radiant heat flux on the sample surface. The heat flow through the focusing lens with the ability to move along the axis was applied to the sample. Changing the geometric characteristics of the optical system can be used for measurements of the ignition of samples condensed systems in a wide range of values

    This article presents a dynamic regime of exposure of the radiant flux on the sample of gun-cotton. Obtained time the ignition of gun-cotton in the heating conditions of increasing heat flux in the range from 0.2 W/cm{2} to 22 W/cm{2}. A comparison of the delay times of the ignition when heated variable and constant heat flux
