Errors in determining the thermophysical characteristics of heterogeneous high-energy materials by the laser-pulse method

An analysis has been carried out with respect to the errors incurred in the determination of the thermophysical characteristics of the high-energy heterogeneous material “aluminum-ammonium perchlorate-butyl rubber” and associated with the radiation transfer of energy in the heated layer under conditions corresponding to the realization of the laser-pulse method in the course of action of a fi nite-length collimated laser pulse on the material surface. The infl uence of the radiation absorption process on the magnitude of this error has been established.
