Problems solved by technology

The following problems exist in the existing calculation method of propellant compression-stretching process parameters: (1) The calculation process needs to rely on the existing test data and correct it through manual experience, and the results obtained by experienced personnel and inexperienced personnel are quite different; (2) The calculated value of the compression-stretching process parameters cannot be corrected in real time. If the pressure parameters are not suitable, the rapid correction calculation cannot be performed; (3) When the compression-stretching parameters are corrected, manual correction is required. It is carried out based on experience, and the comprehensive influence of the formula characteristics of the propellant and the current process conditions cannot be considered
