ERRORS IN DETERMINING THE THERMOPHYSICAL CHARACTERISTICS OF HETEROGENEOUS HIGH-ENERGY MATERIALS BY THE LASER-PULSE METHOD

摘要

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 finite-length collimated laser pulse on the material surface. The influence of the radiation absorption process on the magnitude of this error has been established.
