Abstract:
The heat conduction and mechanics characteristic of multi-perforated propellants are studied by the numerical calculation.Utilizing the finite-difference method,the multi-perforated propellant model with irregular boundary conditions is meshed by non-structural grid.The distribution of temperature field and combustion property of seven-perforated propellants is gained by segregating boundary conditions.Considering that the direct stress is the main form for the thermal stress of propellants,the distribution of radial and axial stress of the propellants is obtained by the distribution of the propellant temperature,and the theoretical foundation is supplied for combustion and crushing mechanism of multi-perforated propellants.
