  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

    將液體火箭發動機燃燒室的冷卻通道設計為斜航線（等傾角螺旋線）槽形，可以大幅度改善燃燒室的冷卻性能.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，提出了五軸控制、四軸聯動的數控片銑刀銑削加工方法.由於燃燒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.燃燒室收斂-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、銑削方式和方向、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.

  4. Thirdly, through assaying the error generated during measuring data, the result manifests : 1 ) the location installed of the transducer and the point thumped affects the experiment result to some extent. if surface - opening cracks is deeper, the location of the transducers installed and the point thumped should be further away from the location of surface - opening cracks. 2 ) when the depth of surface - opening cracks is near to 50mm, it is very difficult to measure the depth of surface - opening cracks because the depth of r _ wave conveying in concrete plates from the different small ball bringing forth exceeds 50mm. 3 ) it is clear from the experiment result, the influence is n ' t big for the diameters of small balls to measure the data while the time interval between two transducers touched firstly has very big influence on the result

    其次，對測量數據進行了誤差分析，結果表明： （ 1 ）傳感器及敲擊點的位置對實驗結果有一定的影響，當開口裂紋的深度較深時，傳感器和敲擊點的位置應該離裂紋較遠； （ 2 ）當開口裂紋深度接近50毫米時，由於實驗中所使用的小球產生的r波傳播深度均超過50毫米，故很難測量出其開口裂紋的深度； （ 3 ）實驗發現，小鋼球直徑的大小對裂紋深度的測量結果影響並不是很大，但是，波的開始上升和下降點的測量精度（即兩信號的時間延遲） ，對測量的結果有很大的影響。
