摘要
Abstract
The mixing is one of the most critical and dangerous processes in the solid propellant manufacturing process.In re-sponse to the problems of large online manufacturing volume and high safety risks in the vertical mixing process,an acoustic reso-nance-elongational rheology continuous mixing system was developed to realize continuous mixing of solid propellants.The effects of different rotational speeds and different mixing processes on the mechanical properties,density and element distribution of the simu-lation slurry with solid content of 73%and 83%were analyzed.The results show that the flowability and surface quality of the sim-ulation slurry obtained by acoustic resonance-elongational rheology continuous mixing are significantly improved compared to elonga-tional rheology;compared with the vertical-elongational rheology,the relative density difference of the slurry is only 0.23%,the strength is slightly lower(modulus and tensile strength are 6.30%and 15.24%lower respectively),and the elongation is higher(5.00%higher).Acoustic resonance and elongational rheology exhibit good process complementarity and mixing efficiency,making them highly feasible for achieving continuous mixing of solid propellants.关键词
