METHOD FOR EVALUATION OF PHYSICAL AND MECHANICAL PROPERTIES OF CHARGES AND OTHER SOLID FUEL ROCKET DURING OPERATION

摘要

1. A method for estimating the physical and mechanical properties and other solid propellant charges in the course of their operation, comprising the use of physical-mechanical parameters and other properties of solid propellants, for certain solid propellants samples at various stages of accelerated aging, characterized in that assessment of physico-mechanical properties and other solid propellant charges in the operation performed by comparing such current quantitative computer tomogra ii charge of solid rocket propellants their density or standard deviation of density, with the same quantitative indices of samples of solid rocket propellants, for which experimentally identified functional dependence of the change of physico-mechanical and other characteristics of the change in their density or standard density deviation obtained from the results of test specimens of solid rocket fuels at various stages of accelerated aging subjected simultaneously controlled by computer tomografii.2. A method according to claim 1, characterized in that it further indicators of physical and mechanical properties and other solid propellant charges are determined by the physico-mechanical tests and other charges witnesses for which tomographic control is conducted in the same terms as for the charge of solid rocket fuels, while the results of the test charges witnesses charge current indicators TRT The specified properties are assigned values ​​equal to the values ​​for certain n. 1, multiplied by the appropriate correction factors, each cat ryh is
