extra thrust 中文意思是什麼
extra thrust
解釋
剩餘推力-
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 -
With the development of multi - variable control technology and aero - propulsion technology, future excellent engine must have the character, which is high ratio in thrust and weight low fuel and long use life. therefore the control system of aero - engine has also been becoming more and more complicated. the precision of control system is also extra higher
隨著高推重比、低油耗、長使用壽命、高機動性航空發動機的研製，現代航空發動機需要控制的變量越來越多、精度越來越高，因此，航空發動機控制系統變得越來越復雜，傳統的航空發動機控制系統是採用機械液壓控制。 -
The main work and achievements are described as follows : ( 1 ) the analysis of the extra - atmospheric kinetic - kill vehicle at first, the motion model and dynamics model of the kinetic - kill vehicle is constructed, and the thrust performance of trajectory - control system and attitude - control system are presented, then the algorithms of realizing the guidance law, the methods of trajectory and attitude control are studied
