The solid rocket ramjet , which combines the techniques of ramjet propulsion and solid rocket propulsion , offers the following advantages for missile propulsion : high specific impulse , simple configuration , high credibility , convenient using and high maneuverability 固體火箭沖壓發動機結合了沖壓技術和固體火箭技術,具有比沖高、結構緊湊、工作可靠、使用方便、機動性好等優點,是新一代超聲速戰術導彈的優選動力裝置。

At the same forum , their papers revealed new rocket propulsion research , including work on hybrid systems that use a combination of propellants easier to handle and store than most propellants in wider use today 在本次論壇上,中國人的論文揭示了其新的火箭推進研究,其中包括一個混合系統,該系統使用了比今天廣泛應用的推進劑更容易貯藏和操作的多種推進劑組合。

Adding rocket propulsion could double this velocity ? and thus the impact momentum ? which would drive them to depths 75 percent greater in granite formations and nearly 1 , 000 percent greater in soft soil 加裝火箭推進器可使速度(也包括沖擊動量)提高一倍,使炸彈鉆入花崗巖的深度增加75 % ,鉆入軟土壤的深度更可增加到10倍之多。

Thrust vector control is one of objects being seeked by engineers in rocket propulsion area 流場控制以及基于此的發動機推力方向控制長期以來都是國內外火箭推進領域廣大工程技術人員追尋的目標之一。

Space propulsion begins with a review of rocket propulsion fundamentals 在太空推進這門課里,我們將以回顧火箭推進基本原理為開端。
