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With the purpose that people in countryside and rural area can listen to the sounds of communist party and chinese government, “ xi xin project ” has been carried out state general bureau of the radio and television and set up tens of 500kw sw radio transmitters, ten of them were installed, whom were th558 with find power amplifier, a kind of ultrahigh power mental - ceramic tetrode from french thomson company
