In actual practice, in particular, when inflaming a charge of the solid propellants rocket engine, combustible materials in the conditions of the fire, etc., ignition is carried out at the dynamic modes of heating by a variable (time dependent) heat flux.The experimental study of characteristics of ignition of the condensed systems by a radiation heat flux it was carried out in the majority of works at constant value of heat flux at the induction period. The dynamic modes of ignition were considered by a convective and radiation heat flux in available literature in publications that is bound, apparently, to technical complexity of carrying out correctly experiments.The technique and results of the experimental study of characteristics of ignition of the condensed systems by a radiation heat flux at the dynamic modes of heating are presented in this report.This work was supported by the Ministry of Education and Science of the Russian Federation under Agreement No. 14.577.21.0157 of 11.28.2014 (unique identifier RFMEFI57714X0157).Keywords: Dynamic regime, ignition, heat flux.416
