对发动机装药无缸浇注技术进行了研究。按国内的二次料斗真空花板除气装药工艺,设计了药浆流入真空系统中成形复杂结构药柱的无缸浇注技术,经过小型燃烧室旋转式无缸连续浇注工艺试验、大型发动机药柱无缸浇注工艺演示试验,验证了无缸浇注的技术可行性。提出在大型固体助推发动机装药中采用无缸浇注工艺成型途径。 Research on engineless cylinderless pouring technology was carried out. According to the domestic secondary hopper vacuum plate degassing charge technology, the non-cylinder pouring technology was designed for forming complex structure of the slurry into the vacuum system. After small-scale rotary combustion chamber without continuous casting process test, the large engine medicine Column unboiled casting process demonstration test to verify the technical feasibility of unboiled casting. Proposed in the large solid propellant charge in the cylinder without casting process molding approach.
