The paper presents the solution of the problem of simulation of the effect of radiant heat fluxes from infrared sources (IRS) on the surface of spacecraft and their modules during complex tests in a vacuum chamber (VC) 600/300. We suggest using empirical dependences as a solution to the problem of promptly obtaining the results of calculating the density of thermal radiation fluxes on... https://www.bekindtopets.com/super-grab-Wizarding-World-Hogwarts-Legacy-Main-Poster-iPhone-14-Plus-Clear-Case-p36756-quick-choice/
