thrust limit 中文意思是什麼
thrust limit
解釋
推力極限-
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 -
Experimental research on uplift force acted on a piece of floor of arch invert water cushion pool and estimation to limit thrust load at skewbacks
反拱水墊塘底板塊上舉力變化規律的試驗研究 -
By analyzing the features of engineering geology of northeast part fenghuang mountain in yanan, the adverse geological problems including landslides, slumps, collapse and hazardous slopes are presented and their stability is assessed by virtue of bishop ' s method and surphas thrust method commonly used in limit equilibrium analysis, in order to supply the reliable basis for future design schemes
摘要通過對鳳凰山東北麓工程地質特徵的分析，指出該區存在的不良地質問題有滑坡（滑塌）以及危險斜坡等，並對各滑坡（滑塌）以及危險斜坡的變形破壞特徵進行了分析，最後運用斜坡（滑坡）穩定性計算中常用的瑞典法、畢肖普法和剩餘推力法對其進行了穩定性驗算，為鳳凰山東北麓後期的治理設計提供了依據。 -
The thrust bearings are capable only to sustain the axial loads, with low limit speed. they have two stress modes, i. e. one - way thrust and two - way thrust
