Abstract: FIELD: rocket and space equipment.  
     SUBSTANCE: invention relates to methods of control tests of rocket and space equipment to confirm the requirements for reliability. It particularly relates to computational and experimental methods for evaluating and monitoring the reliability of technical systems (TS) by variable state parameters (SP). The technical result is achieved by the proposed method for controlling the dynamics of the parametric reliability of technical systems. The method consists in the fact that a controlled technical system is made of elements with the same spread of parameters. The elements do not have hidden defects. The technical system is subject to boundary tests under the influence of operational factors. The change in reliability is taken into account. The reliability is evaluated. The method is characterized by the fact that informative parameters of the technical system state are identified. The permissible intervals are determined for each state parameter. The state parameters, which ensure the reliable operation of the technical system, are determined. The values of the state parameters are measured in the process of boundary tests of the technical system at times t i . A model of changes is built in the average value of each state parameter. Probability densities of estimates of model parameters are built for state parameters depending on the measurement results. The unbiased estimates of the parameters of the models are determined. Unbiased estimates of the probability of failure-free operation of the technical systems are determined depending on time. Their standard deviations for each parameter of the state are determined. The estimates of the probability of failure-free operation of the technical system and its standard deviation for all parameters of the state are determined. The lower limit of the probability of the failure-free operation of the technical system is determined. The reliability of the technical system is predicted up to the specified time of the target use of T tu . The obtained estimates of the reliability are compared with the required values and the decision to accept the technical system into operation is justified. A further period of target use is set for this system with the required level of reliability. 
     EFFECT: invention makes it possible to reduce the number and a period of testing a TS while increasing the estimation accuracy and reliability of the reliability control and justified acceptance of the TS into operation as well as the possibility of predicting the parametric reliability of the TS and determining the further period of target use taking into account the required (specified) level of reliability.
