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By adjusting many variable geometry components of the engine, bypass ratio can be changed during large range ( the most 0. 25 of military fighter ). the high specific thrust characteristic of turbojet engine and the low specific fuel consumption characteristic of the turbofan engine can be realized during different flight phase by the usage of vce technology

本文在對各種數學模型比較的基礎上,應用二維水動力數學模型研究典型石質汊流灘? ?廣西潯江鯽魚灘航道整治工程方案,通過各方案計算結果比較,分析了不同汊道的開挖及汊道內不同開挖面積、開挖范圍以及開挖方式所引起的分流比及工程區域航道水力條件的變化規律,研究結果表明: ( 1 )對于石質汊流灘來說,在某一汊道通過局部開挖河槽,擴大過水斷面面積,可以達到降低工程段流速、改善局部水流條件的目的。Excavating riverbeds in one channel may not only reduce the velocity area in some areas but also increase the velocity in other areas by increasing flow rate in this channel without correspondent changes in riverbeds of rocky rapids. in result, the velocity in waterway may be increased instead of be reduced, the flow condition may also be deteriorated. thus, which branch should be excavated and how to excavate in improving the flow condition of the branch should be further explored
但在分汊河道內,情況較為復雜,在一汊河道內採取開挖措施后,雖然其過水斷面有所增加,局部流速相應降低,但是由於工程后,汊道的分流比將會相應變化,而石質河床一般無法通過沖淤變化以適應水流條件的改變,因此,航道內工程處的流速可能降低,也可能不降反而有所增加,惡化了航道的水流條件。The positive is that as a substitute of old channel or a part of the new channel shiplock maintains the continuation of channel and makes possible the channel free from navigational obstruction and waterway transportation progress. the negative is that shiplock at the same time brings some problems to waterway transportation, such as the long time passing through shiplock, the piling up of vessels, making less other ' s benefits and making more other ' s costs, making conditions and forms of transportation change, making more complicated the waterway transportation safety management and navigation order keeping, and adding up transportation costs
在經濟學意義上,船閘具有正負外部性,正的外部性為,船閘作為原航道的替代物或新航道的一部分,保證了航道的連續性,為保證航道暢通、航運發展提供了可能;負的外部性為,船閘同時給航運帶來了一些問題,如船舶過閘時間長、船舶積壓,引起他人效用的減少和成本增加,以及運輸組織條件、方式改變,使水上交通安全管理和船舶航行秩序維護更加復雜,增加運輸成本。Maintain forward progress at a slow, steady speed or stop with no sudden course changes
