Webb11 apr. 2024 · A polyamide 12(PA12) reinforced with glass beads (GBs) solid rocket motor (SRM) produced by 3D Printing is proposed in the paper. The ablation research of the combustion chamber is studied by simulating the motor’s operating environment through ablation experiments. The results show that the maximum ablation rate for the motor … WebbThe allowable deflection limits under SLS conditions are defined by BS 6180:2011, and as such remain the same under permissible or limit state design conditions. However, the …
