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
採用直升機進行電力作業已經成為世界電力工業的潮流，應用直升機巡視和維護500千伏陽淮線，應堅持把安全飛行作為首要目標，宜分近期和遠期兩個目標分階段實施，先租機，再購機；直升機的選型，主要從安全性和經濟性兩方面考慮，在起步階段租賃bo - 105c直升機；要根據作業項目和方法選擇機載儀器設備；用直升機進行輸電線路巡檢，能極大地提高勞動生產率，具有明顯的經濟效益，並將提高我國直升機運用水平，促進我國通用航空事業的發展，從而帶動相關行業的發展。Firstly, this paper summarizes modern weaponry stealth technology at home and abroad, and lays special emphasis on analyzing stealth problem of cruise missile ’ s guidance head cover, aerocraft radar canopy and other privileged sites. secondly it makes a research on related theories of transparent metallic mesh that applied to missile ’ s guidance head cover and aerocraft radar canopy, and deduces relational expression between transparent metallic mesh structural parameters and radar wave - shielding efficiency, infrared transmitting. we use laser direct writing technique to fabricate a metallic mesh ( dimension : 70mm 70mm ; line width : 5 m ; period : 350 m ) on glass surface, then do experiment to test radar wave - shielding of metallic mesh via radar transmitting and receiving device
本文首先綜述了國內外現代武器系統隱身技術方法;重點對巡航導彈導引頭罩和飛機雷達艙罩等特殊部位的隱身問題進行了研究，研究了金屬網柵用於導彈頭罩和飛機雷達艙罩隱身的相關理論，推導了金屬網柵結構參數對雷達波屏蔽效率和透紅外關系式;用激光直寫工藝，在玻璃表面上製作了一塊面積為70mm 70mm ，線寬為5 m ，線周期為350 m的金屬網柵;在實驗室里用雷達發射和接收裝置測試了網柵對雷達波的屏蔽實驗;認為利用金屬網柵技術對雷達波具有一定的屏蔽作用，而且不影響精確制導的紅外線高效透過。A flight trajectory math model of an assumed cruise aircraft is built according to a simple blue print of the flight control system, with the foundation of a particular analysis of its kinematics and dynamics. a linear light - disturbed minor - cycled movement model and the transform function models are got through some simplifications
本文以某個虛構的巡航式飛行器的飛行控制系統為研究對象，首先討論了一個簡單的總體方案，然後根據此方案，在詳細分析此飛行器運動學與動力學的基礎上，建立了飛行器飛行模擬數學模型，並在允許的條件下進行簡化得出了此飛行器線性化小擾動短周期運動模型與傳遞函數模擬模型。" with the implementation of clearance data link service, the provision of pre - departure clearance information in respect of the departure routes, altitude restrictions and cruising levels etc., which are used to be provided through radio communication, can now be transmitted via data link for display or print out in the cockpit to reduce pilots workload, " mr lam said
自從推出起飛前放行指示數據鏈路服務后，有關離場路線、高度限制和巡航高度層等資料現已可在駕駛艙內顯示或列印出來，從而減輕飛行員的工作量。Through on - ling circuit supervision, the airport, maintenance personnel can detect lamp faults and promptly carry on maintenance, thus safeguarding flight safety when an airplane takes off and lands, and enhancing the working efficiency of the airfield light maintenance
