【摘要】：伴隨著我國低空空域的進(jìn)一步開放以及通航的飛速發(fā)展,如何為通航提供運(yùn)行支持服務(wù)逐漸受到關(guān)注,而飛行計(jì)劃評估就屬于運(yùn)行支持服務(wù)的范疇。本文深入研究了通航飛行計(jì)劃評估技術(shù)及實(shí)現(xiàn)方法,給出了一套適用于我國通航的二三維一體化飛行計(jì)劃評估系統(tǒng)的設(shè)計(jì)和實(shí)現(xiàn)方法,從而為通航飛行計(jì)劃的審批提供技術(shù)支撐。首先,本文針對通航飛行計(jì)劃評估方法展開研究,分析包括垂直航跡剖面、配載平衡、燃油消耗、作業(yè)區(qū)域氣象條件等在內(nèi)的評估指標(biāo),確定各個(gè)評估指標(biāo)的計(jì)算方法,構(gòu)建有效的飛行計(jì)劃評估指標(biāo)體系,提出了適用于我國通航飛行計(jì)劃評估的系統(tǒng)流程。其次,為了能夠針對評估后的計(jì)劃航跡給出優(yōu)化方案,本文研究了通航飛行計(jì)劃航跡優(yōu)化方法,通過構(gòu)建柵格化規(guī)劃空間,將通航飛行器的最大爬升/下降角、最小航跡段長度、飛行高度、預(yù)設(shè)航跡點(diǎn)等多個(gè)約束條件導(dǎo)入約束模型,從搜索空間、搜索策略、啟發(fā)函數(shù)上對傳統(tǒng)A*算法進(jìn)行改進(jìn),建立適用于我國通航低空飛行特色的垂直剖面航跡代價(jià)模型,采用層次分析法確定航跡代價(jià)函數(shù)各權(quán)重系數(shù),最終實(shí)現(xiàn)對通航飛行計(jì)劃航跡的優(yōu)化。最后,本文給出了通航飛行計(jì)劃評估系統(tǒng)的設(shè)計(jì)和實(shí)現(xiàn)方法,系統(tǒng)基于U-GIS二三維一體化地理信息平臺(tái),應(yīng)用C/S(客戶端/服務(wù)器)架構(gòu),系統(tǒng)實(shí)現(xiàn)采用Microsoft Visual Studio 2010集成開發(fā)環(huán)境,通過ADO數(shù)據(jù)訪問技術(shù)來完成前臺(tái)與后臺(tái)的連接與操作,代碼主體部分使用C#實(shí)現(xiàn),同時(shí)給出了單元測試、集成測試等測試驗(yàn)證的實(shí)現(xiàn)方法,系統(tǒng)運(yùn)行與測試結(jié)果表明本系統(tǒng)可以為通航提供有效的飛行計(jì)劃評估服務(wù)。論文中所設(shè)計(jì)和研制的飛行計(jì)劃評估系統(tǒng),已作為國家科技支撐計(jì)劃重點(diǎn)課題“通用航空綜合運(yùn)行支持系統(tǒng)”所研制系統(tǒng)的重要組成部分,于2015年11月10日通過國家科技部驗(yàn)收,并將在實(shí)際應(yīng)用中不斷完善。
[Abstract]:With the further opening of China's low-altitude airspace and the rapid development of navigation, how to provide operational support services for navigation has been gradually concerned, and flight plan evaluation belongs to the category of operational support services. In this paper, the evaluation technology and realization method of navigable flight plan are deeply studied, and the design and implementation method of a two dimensional and three dimensional integrated flight plan evaluation system suitable for navigation in China are given. In order to provide technical support for the approval of navigable flight plan. First of all, this paper studies the evaluation method of navigable flight plan, analyzes the evaluation indexes, including vertical track profile, load balance, fuel consumption, meteorological conditions of the operating area, and determines the calculation methods of each evaluation index. An effective evaluation index system of flight plan is constructed, and the system flow is put forward for the evaluation of navigable flight plan in China. Secondly, in order to give the optimization scheme for the evaluated flight path, this paper studies the route optimization method of the navigable flight plan. By constructing the rasterized planning space, the maximum climbing / falling angle of the navigable vehicle can be obtained. The minimum track length, flight height and preset track point are introduced into the constraint model, and the traditional A * algorithm is improved from the search space, search strategy and heuristic function. A vertical profile track cost model suitable for China's navigable low-altitude flight is established. The weight coefficients of the track cost function are determined by using the analytic hierarchy process (AHP), and finally the route optimization of the navigable flight plan is realized. Finally, this paper gives the design and implementation method of the navigable flight plan evaluation system. The system is based on the U-GIS integrated geographic information platform, using the C / S (client / Server) architecture, the system is implemented under the Microsoft Visual Studio 2010 integrated development environment. Through the ADO data access technology to complete the foreground and background connection and operation, the main part of the code is implemented with C #. At the same time, the implementation methods of unit test, integration test and other test verification are given. The system operation and test results show that the system can provide an effective flight plan evaluation service for navigation. The flight plan evaluation system designed and developed in this paper has become an important part of the research and development of general aviation integrated operation support system, which is the key subject of the National Science and Technology support Program. Passed the National Ministry of Science and Technology acceptance on November 10, 2015, and will continue to improve in practical applications.
