此航天特異零件各部分回轉軸不是同一直線,因此針對這種特性對斜圓柱段和斜圓柱與球缺端頭過渡段的纏繞做了理論上的分析與設計。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With argumentation system and differential system, gnss is capable of supporting en route flight and cat iii precision approach. this system can meet the need of all flight phases in terms of integrity, precision and continuity. with the application of area navigation and required navigation performance ( rnp ), this would make the parallel route, random route and direct flight route possible, and also improves the efficiency of air space and the flight safety
在導航系統中,全球衛星導航系統是其主要成分,通過增強系統和差分技術, gnss具有支持從航路飛行到類精密進近的能力,在完好性、精度、可用性、連續性上都可以滿足飛行各階段的要求;隨著區域導航和所需導航性能的實施,平行航路、隨機航路和起點和終點之間的大圓航線直飛得以實現,提高了空域利用率和飛行安全。Based on the current helicopter operation at home and abroad on transmission line and its technical development trend, the paper has carried on research and demonstration on feasibility to apply helicopter in cruising inspection of yang - huai 500kv transmission line from various aspects as its significance, necessity, selection of operating management mode and technical working plan as well as its rationalization economically etc. applying helicopter to operate on power transmission has been tendency of the world power industry. on using helicopter to cruise, inspect and maintain the yang - huai 500kv transmission line, the first objective is to insist on flying safety. two steps should be taken seperately for short term and long term objective. first, to rent helicopters and then, to buy them
