      本研究主旨在於以國籍航空公司擁有之V-2500 發動機為藍本,進行發動機HPT(高壓渦輪段)失效問題探討及維修方案之研究,首先以基本熱力、氣動力學原理為發展出來的ONXOFFX軟體,對發動機系統進行設計點與離點性能模擬與分析;並應用發動機狀態監控(engine condition monitoringECM)軟體與分析方法對在離點狀態運作下HPT之NGV(噴嘴導葉片)熱損情況分析並提出改善方案,在提高循環參數 (渦輪段第一區冷卻氣流)1﹪後,使NGV之膜層冷卻(film cooling)加強而避免熱損再次發生,同時降低單位耗油率。論文中並對發動機失效組件工作原理與操作配合上進行探討,最後對於大型商業發動機提出快速之維修決策,為日後發動機故障排除與診斷建立基礎。

 

 Abstract

          By studying the IAE V2500 engines serviced in Taiwan. This thesis conducted and employed the engine condition monitoring and performance analysis using the ONX and OFFX software base on the aerothermodynamics. This study carried out both the performance simulation and analysis as IAE V2500 engine through “on design” and “off design ”conditions. For the failure of high pressure turbine nozzle guide vanes case the author also provide the recommendable suggestion to adjust the parameter of the CYCLE cooling air #1 mass flow rate, therefore the temperature gradient of  NGV decrease and the engine could avoid the same case happen and meanwhile lower the SFCspecific fuel consumption.Regarding the failure of engine componentthe operation principle and component matching were addressed here too. For the large commercial engines the thesis provide the rapid maintenance decision and further would be the fundamental of the engine troubleshooting and diagnosis.
