  1. 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

    將液體火箭發動機室的冷卻通道設計為斜航線(等傾角螺旋線)槽形,可以大幅度改善室的冷卻性能.斜航線冷卻槽的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、四聯動的數控片銑刀銑削加工方法.由於室外表面的母線輪廓復雜,手工編制數控加工程序難度大.為了解決數控加工程序的編制問題,研究了斜航線的數學模型,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的斜航線數控加工程序.室收斂-擴張段的母線斜率變化大,加工難度大,是斜航線冷卻通道加工的最典型工件.經過理論分析和實際切削實驗,研究了針對該類型工件的片銑刀直徑選擇、銑削方式和方、刀具調整和起刀點的設置等多項實際的加工方案.採用上述的一系列技術,已經成功地加工了數十個合格工件.經過兩年多的實際生產過程應用,驗證了所開發的斜航線冷卻通道加工方法的正確性和可行性.這些加工技術的研製成功,對其他相似類型零件的加工亦具有參考意義
  2. The most important of the results is the finding of significant axial variations of the combustion parameters.

    最重要的結果是參數的變化顯著。
  3. More often than not the combustion noise refers to the noise radiated from the cylinder cap, piston, rod, crankshaft to the engine body propelled by the pressure vibration generated out of the combustion inside the cylinder

    噪聲和機械噪聲很難嚴格區分,通常將由於氣缸內所形成的壓力振動通過缸蓋、活塞-連桿-曲-機體外輻射的噪聲稱之為噪聲。
  4. The results indicate that auto - ignition occurs more easily when the igniter uses the cross injector with rearward facing step, the height of the rearward facing step influences the stability of the combustion flame, the longer the combustor characteristic length is, the more easily auto - ignition occurs

    研究結果表明,採用帶後臺階的橫噴注器比氣液同剪切噴注器更易於自,後臺階的高度對室火焰穩定有影響,室的特徵長度越長,越利於自
