  1. 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
  2. To optimize specific impulse to 700s or 800s, the thrust - weight ratio could be improved to 1. 23 or 1. 41, it is enough to achieve the launch requirement for this vehicle

    進一步將比沖優化至700s或800s ，可以將推重比提高至1 . 23或1 . 41 ，這樣就完全能夠保證發射任務的完成。
  3. Compress disk is the very important rotational component in the areoengine. when the compress disk is working, the grads of temperature and stress between the rim and the center of the disk are great. in order to raise the thrust - weight ratio of the disk and reduce oil consumption. the best prospective way is the dual alloys disk used

    壓氣機盤是航空發動機上一個很重要的轉動部件，壓氣機盤工作時，輪緣和輪轂溫度梯度和應力梯度較大，為了提高飛機發動機推重比、減低耗油量，要求壓氣機盤的工作溫度、使用性能更高，雙合金盤製造是最有發展前景的技術。
  4. Weight to thrust ratio

    重量推力比
  5. Two key problems were solved : 1 ) to cancel the disturb of microwave cable rigidity on small thrust measurement of mpt adopting soft wave - guide without jacket as elastic linker, 2 ) to successfully realized separation of self - weight and thrust of mpt adopting small thrust measurement device of balance type, electromagnetic feedback and automatically compensation. so, the measurement precision and stability were greatly raised in actually application of small thrust measurement device
