                                                                                                                                                                    航空維修是指對飛機及其上的技術裝備進行的維護和修理,確保飛機的安全,航空維修是飛機使用的前提和必要條件,也是航空業的重要組成部分。而航空發動機是飛機的心臟,航空發動機維修既是飛機維修的一部分,也是航空機務工作的重要組成部分。

                                                                                                                                                                  航空發動機維修的重要性,主要是由于航空發動機是由多種類型零、部件組成的復雜機器,在高溫、高壓、高轉速及惡劣的環境不斷變換的工作狀態中工作,要求重量輕、推力大、耗油低、工作可靠、壽命長、成本低,而且發動機結構還要不斷更新,導致航空發動機維修所占的比重也不斷的加大。

                                                                                                                                                                  近年來,航空設備不斷的應用最新科技成果,性能更高級,技術更加綜合,結構也更加復雜,給航空設備的定期維修、快速維修特別是大修帶來很大挑戰。因此,國內外航空發動機的維修裝備和手段也在不斷發展,推陳出新,使航空發動機的維修手段更加現代化。

                                                                                                                                                                  航空發動機最易發生故障的區域為高壓壓氣機、燃燒室及高壓渦輪。傳統對航空發動機的檢測、維修,都是通過分解的方法進行檢測,這樣不僅耗費時間、人力、財力,而且對發動機拆解本身對航空發動機來說也是一種很大的損害,大大降低航空發動機的使用壽命。內窺檢測技術為維修人員提供了一種非常有效的檢查發動機內部狀況的方法。

                                                                                                                                                                  在一般情況下,航空發動機內窺鏡檢測分為定期檢查、針對性檢查和擴大區域檢查三種。工業內窺鏡在航空發動機檢測記錄方面的重要性,主要是表現在以下三方面:

                                                                                                                                                                  1)為航空發動機故障分析提供依據

                                                                                                                                                                  2)為航空發動機修理提供依據

                                                                                                                                                                  3)為航空發動機制造廠家提供有價值的信息

                                                                                                                                                                  航空發動機維修費用通常占飛機總維修費用的一半以上,在保證適航的前提下降低航空發動機的維修成本,是所有航空公司關注的問題。工業內窺鏡檢測作為航空發動機維護中的重要手段,對降低航空發動機維修成本有及其重要的作用,是航空發動機維護的基礎。
