Description: В статье рассмотрены составляющие метрологического обеспечения при бросковых (статодинамических) испытаниях космических аппаратов. Показаны особенности программных комплексов для математического моделирования теплонапряжённых конструкций. Предложен способ получения оценки отдельных метрологических характеристик измеряемых параметров для улучшения точности модели напряжённо-деформационного состояния конструкции космического аппарата при посадке на грунт. Обобщён опыт анализа оценок погрешностей при статодинамическом нагружении конструкции космического аппарата The article reviews the elements of metrological support during the drop (static-dynamic) tests of spacecraft. The features of software packages for mathematical simulation of heat-stressed structures are presented. There is a proposed method of estimating single metrological characteristics of the measured parameters in order to improve the accuracy of the stress-strain state model of the spacecraft structure during landing on the ground. The article summarizes the experience of analyzing margin of error in static-dynamic loading of the spacecraft structure
