Modeling and Simulation of Interior Ballistics Based on Actual Combustion Characteristics of Propellants

A novel interior ballistic model was established by revising actual combustion characteristics describing the relationship between burned propellants (ψ) and pressure impulse (I t ). The discrepancy between theory and experiment for gas releasing of porous propellant was investigated. Furthermore, t...

Summary:A novel interior ballistic model was established by revising actual combustion characteristics describing the relationship between burned propellants (ψ) and pressure impulse (I t ). The discrepancy between theory and experiment for gas releasing of porous propellant was investigated. Furthermore, the model was tested for multiperforated propellants, with relative errors less than 1 and 3% for the maximum pressure and velocity, respectively, indicating that this is a good model to estimate the interior ballistics performance for multiperforated propellants.
