Abstract : solid propellant rocket motors are preferred for most ballistic missiles because they need simple maintenance and can be launched quickly. but the conventional thrust termination devices limit the depletion of every stage ' s grain and increase some extra - weight. an improved method for designing a multi - stage solid rocket based depleted shutdown was provided. in order to solve the problem of lack of thrust termination devices, a device to adjust the burnout angle will match the final burnout velocity and satisfy the desired range. the method can also limit the detection from anti - ballistic missile system
文摘:由於維護簡單和發射快速,彈道導彈多用固體火箭發動機,但繁雜的推力終止裝置使各級裝藥不能耗盡並讓結構增重.提出了一種對基於耗盡關機多級固體火箭概念設計的改進方法,此方法滿足導彈系統主要的戰技要求.為解決無推力終止裝置的末速不準問題,可在末級發動機採用姿態調整裝置,對射角進行調整,配合末速以滿足射程要求.本方法還可抑制敵方反導探測Uncertainty optimization design of solid rocket motor grain
