nozzle exit area

基本解釋

There exists an optimal exit area of secondary nozzle to get maximum thrust of rocket ejector.
存在一個最優(yōu)的二次噴管出口面積，使發(fā)動機推力最大。
There exists an optimal exit area of secondary nozzle to result in a maximum thrust of rocket ejector in the light of the investigated ejector chamber structure.
在文中所研究的引射燃燒室結(jié)構(gòu)條件下，存在一個最佳二次噴管出口面積，它能使引射火箭的推力達到最大。
Results show that the maximum stress appears in entrance area of the nozzle and minimum stress in middle area, while the stress of exit area is lower than entrance area and higher than middle area.
試驗顯示噴嘴的沖蝕磨損在噴嘴入口最嚴重、出口次之、中間區(qū)域相對較小。試驗結(jié)果與應(yīng)力分析結(jié)果一致，得出磨料噴射加工中噴嘴入口、出口處承受的高拉應(yīng)力是造成其沖蝕磨損嚴重的主要原因的結(jié)論。
