第1章 緒論 在過去十幾年中，微電子技術、光電技術、計算機、通信、信息處理、新材料等高技術的發(fā)展,為無人機及其機載設備等提供了良好的發(fā)展條件，無人駕駛運載工具開始真正呈現復興的勢頭。國內外都十分重視該領域的研究，并逐漸在軍事和其他方面得到應用。表11各國無人水面艇參數表 在水面高速無人艇方面的研究目前我國還處于起步階段。北京奧運籌辦委會呼吁國人生產自己的奧運船艇，并列出了剛性充氣艇這個空缺項目，希望國內有廠家能夠研制生產。結果表明，即使對于如此高的航速．采用切片法預報縱向運動，仍可以獲得相當滿意的結果．因此目前在中國．對圓舭快艇在波浪中的縱向運動響應仍普遍采用切片法。哈爾濱船舶工程學院的蘇永昌，趙連恩等研究開發(fā)了新式槽道型滑行艇[4]。我國是世界上唯一一個沒有實現國家統一的大國，為維護國家統一的臺海戰(zhàn)爭爆發(fā)的可能性始終存在。第2章

。在航速較高時，螺旋槳還容易產生空泡，從而導致效率損失。吸水裝置位于艦船的首部，含有吸水口、吸水口防護罩、吸水口開關，吸水口開設在艦船的首部，吸水口防護罩罩住吸水口的開口部分，聯接在艦船的殼體上，吸水口開關的進水端聯接吸水口的收口端，其出水端與輸水裝置中的輸水管的前端相聯，增壓泵的出水端與增壓輸水管的前端相聯。調向閥門含有球形閥體、球弧形閥瓣、圓柱形閥軸、進水端、正向出水端、側向出水端、底座，閥瓣緊套在閥體內，通過閥軸轉動改變出水方向，在關閉側向出水端的同時開啟正向出水端，或在開啟側向出水端的同時關閉正向出水端，使來自噴水機的高壓水流或從正向噴頭噴出，或從逆向噴頭噴出，從而使艦船或前進、或轉向、或倒退，達到調向目的。設原動主機的功率為Np，水泵連軸節(jié)處的傳送效率為，則推進泵的收到功率是水泵的主要作用是把機械能變?yōu)樗δ?，主要參數是流量Q和楊程H,因此，水泵的輸出功率為, 水泵的效率為管道系統在輸入的功率后，輸出推動船前進的功率為。中國正積極進行聲納在水中傳輸特性的研究，并在該領域取得一定的成功。學習形勢船舶與海洋工程專業(yè)是培養(yǎng)從事船舶、水下運載器及各類海洋結構設計、研究、生產制造、檢驗及海洋開發(fā)技術經濟分析的高級工程技術人才的學科。此外，還可爭取留學資格到美國、加拿大、英國、挪威、德國、日本等國留學深造。這個專業(yè)的學生主要學習物理、數學、力學、船舶及海洋工程原理的基本理論和基本知識；掌握船舶與海洋結構物的設計方法；具有船體制圖，應用計算機進行科研的初步能力；熟悉船舶與海洋結構物的建造法規(guī)和國內外重要船級社的規(guī)范；了解造船和海洋開發(fā)的理論前沿，新型艦船和海洋結構物的應用前景和發(fā)展動態(tài)；掌握文獻檢索、資料查詢的基本方法。再加上目前開設相關專業(yè)的學校已經不多，物以稀為貴，所以船舶與海洋工程這個專業(yè)的畢業(yè)生出去后容易受到用人單位的歡迎。例：Lathe sizes range from very little lathes with the length of the bed in several inches to very large ones turning a work many feet in ，小的車床其車身只有幾英寸，大的車床能車削數英尺長的工件。they are referred to as ?principal dimensions‘.The ship, like any solid body, requires three dimensions to define its size, and these are a length, a breadth and a of these will be considered in dimensions Length There are various ways of defining the length of a ship, but first the length between perpendiculars will be length between perpendiculars is the distance measured parallel to the base at the level of the summer load waterline from the after perpendicular to the forward after perpendicular is taken as the after side of the rudder post where there is such a post, and the forward perpendicular is the vertical line drawn through the intersection of the stem with summer load ships where there is no rudder post the after perpendicular is taken as the line passing through the centre line of the rudder perpendiculars and the length between perpendiculars are shown in Figure length between perpendiculars(LBP)is used for calculation purposes as will be seen later, but it will be obvious from Figure 1 that this does not represent the greatest length of the many purposes, such as the docking of a ship, it is necessary to know what the greatest length of the ship length is known as the length of the extreme point at the after end to a similar point at the forward can be clearly seen by referring again to Figure most ships the length overall will exceed by a considerable amount the length between excess will include the overhang of the stern and also that of the stem where the stem is raked modern ships having large bulbous bows the length overall LOA may have to be measured to the extreme point of the third length which is often used, particularly when dealing with ship resistance, is the length on the waterline is the distance measured on the waterline at which the ship is floating from the intersection of the stern with the waterline to the length is not a fixed quantity for a particular ship, as it will depend upon the waterline at which the ship is floating and
