  2. Disigning coolant channel on the firebox of liquid rocket engine to loxodrome ( equal - angle helix ) groove can improve firebox coolant capability greatly. because the width dimension of loxodrome groove is narrow and the depth is deep, some machining methods are incapable, such as end - milling or electrochemistry. according to the peculiarities, a cnc disk - cutter - milling method which is composed of five motion axes with four simultaneously interpolated ones is researched. because most firebox generatrix is composed of complex curves, it is very difficult to get cnc cutting program with manual means. in order to deal with the problem, the loxodrome mathematics model is studied, and an auto - programming software system is developed. the software system can generate cnc cutting program of loxodrome on many kinds of turned surface. the constriction - distension segment of firebox is the most representative workpiece. the sharp changing of its generatrix slope makes loxodrome milling difficult. with the theory analyzing and practice cutting experiment, some applied techniques, which include milling mode and direction, choosing cutter diameter and cutting start point setting, are developed. adopting the technology above, tens regular workpiece have been manufacturing. the two - year manufacture practice has confirmed the validity and feasibility of developed loxodrome coolant channel milling method. the developed technology is also worth to be referenced to other similar workpiece

    將液體火箭發動機燃燒室通道設計為斜航線(等傾角螺旋線)槽形,可以大幅度改善燃燒室性能.斜航線槽寬尺寸較小而槽深尺寸較大,所以無法使用棒銑刀銑削、電化學等加工方式.針對這些特點,提出了五控制、四聯動數控片銑刀銑削加工方法.由於燃燒室外表面母線輪廓復雜,手工編制數控加工程序難度大.為了解決數控加工程序編制問題,研究了斜航線數學模型,開發了自動編程軟體系統.使用該系統,可以生成多種母線輪廓回轉體外表面上斜航線數控加工程序.燃燒室收斂-擴張段母線斜率變化大,加工難度大,是斜航線通道加工最典型工件.經過理論分析和實際切削實驗,研究了針對該類型工件片銑刀直徑選擇、銑削方式和方、刀具調整和起刀點設置等多項實際加工方案.採用上述一系列技術,已經成功地加工了數十個合格工件.經過兩年多實際生產過程應用,驗證了所開發斜航線通道加工方法正確性和可行性.這些加工技術研製成功,對其他相似類型零件加工亦具有參考意義
  3. 4 ) in a pre - swirl rotator - stator cavities with discrete pre - swirl nozzles and blade - cooling entry holes, the influences of pre - swirl angle and flow parameter on the flow and heat transfer characteristics were numerically investigated. the correlation for average nusselt number vs rotating reynold number or non - dimensional mass flowrate were established. the results show that : advantage of per - swirl inflow is the effect of cooling the blade - cooling entry holes ; pre - swirl inflow increases heat transfer in rotating disk of pre - swirl chamber ; as pre - swirl angle increases, local nusselt number decreases in pre - swirl chamber ; the temperature of stator of inner rotator - stator chamber and per - swirl chamber decreases as rotating reynold number increases ; when the axial mass flowrate maintains constant, heat transfer in the rotating disk of inner rotator - stator cavities does n ' t change as per - swirl mass flowrate increases, while heat transfer in the rotating disk of per - swirl chamber increases ; when the pre - swirl mass flowrate maintains constant, change of the axial mass flowrate has effect on the whole cavity

    結果表明,預旋進氣優點在於增強了葉片孔附近對流換熱效果,局部努謝爾數隨預旋角增大而有所減小;隨旋轉雷諾數增加,不論是內轉靜腔室還是預旋腔室靜盤上溫度都不同程度降低:當中心進氣質量流量不變時,隨預旋進氣質量流量增加,內轉靜腔室轉盤盤面上換熱基本沒有變化,而預旋腔室轉盤盤面上換熱效果增強;當預旋進氣質量流量不變時,中心進氣質量流量改變對整個盤腔都有影響。
