【摘要】：隨著我國低空區(qū)域逐步有序開放以及私人飛機(jī)的保有量不斷增多,通用航空產(chǎn)業(yè)迎來了新的發(fā)展機(jī)遇�；钊胶娇瞻l(fā)動機(jī)的維修保養(yǎng)成為通用航空維修企業(yè)一項非常重要的工作內(nèi)容,通用航空發(fā)動機(jī)性能測試任務(wù)量的大幅上漲是航空維修企業(yè)發(fā)展的必然趨勢。論文以LYCOMING水平對置式全系列發(fā)動機(jī)為對象,設(shè)計一套適合于通用航空維修企業(yè)使用的、可滿足多型號活塞式通用航空發(fā)動機(jī)運(yùn)轉(zhuǎn)參數(shù)測試、性能評估的測試系統(tǒng),并編制相關(guān)實驗標(biāo)準(zhǔn)及試驗方法。整個系統(tǒng)的設(shè)計過程在滿足性能測試要求的基礎(chǔ)上,以降低制作成本,操作方便、測試耗時較短為主要指導(dǎo)思想。分別完成了對試車室的布置、試車臺架的安裝、燃油供給系、滑油冷卻系以及控制系統(tǒng)等各系統(tǒng)進(jìn)行了合理的方案設(shè)計和參數(shù)匹配。設(shè)計方面利用了Auto CAD和CATIA等設(shè)計軟件對試車臺架進(jìn)行了整體設(shè)計,并完成對臺架的實際校核,確定臺架的制作材料及結(jié)構(gòu)的合理性。控制系統(tǒng)通過安裝在發(fā)動機(jī)不同部位的傳感器實時地將數(shù)據(jù)通過CAN總線傳輸至上位機(jī),數(shù)據(jù)采集器選擇RDAC XF MAP采集模塊,數(shù)據(jù)顯示器選擇XTREME EMS發(fā)動機(jī)監(jiān)測模塊進(jìn)行數(shù)據(jù)采集、顯示及處理工作。編制試車工藝規(guī)范,通過大量的試車試驗驗證了整套設(shè)計方案的可行性,并在試驗測試過程中對各個系統(tǒng)參數(shù)進(jìn)行了進(jìn)一步的調(diào)試,得出更為合理有效的系統(tǒng)參數(shù)和設(shè)計方案。
[Abstract]:With the gradual orderly opening of low-altitude areas and the increasing number of private aircraft in China. The general aviation industry ushered in a new development opportunity. The maintenance of piston aeroengine has become a very important work content of the general aviation maintenance enterprise. It is an inevitable trend for aeronautical maintenance enterprises to increase the number of performance testing tasks of general purpose aeroengine. This paper takes the LYCOMING horizontal set full-series engine as the object. A test system suitable for general aviation maintenance enterprises is designed, which can meet the operational parameters test and performance evaluation of multi-model piston general aero-engine. The design process of the whole system is based on meeting the requirements of performance testing in order to reduce the production cost and operate conveniently. The main guiding principle is the short test time. The layout of the test room, the installation of the test bench and the fuel supply system are completed respectively. Various systems such as oil cooling system and control system have carried on reasonable scheme design and parameter matching. In the aspect of design, the overall design of test bench has been carried out by using Auto CAD and CATIA design software. And the actual verification of the bench is completed, and the rationality of the material and structure of the bench is determined. The control system transmits the data to the upper computer through the CAN bus through sensors installed in different parts of the engine in real time. The data collector selects the RDAC XF MAP acquisition module, and the data display selects the XTREME EMS engine monitoring module to collect the data. Display and processing work. Compile test process specifications, through a large number of test tests to verify the feasibility of the entire design, and in the process of testing the system parameters for further debugging. More reasonable and effective system parameters and design scheme are obtained.
