北京理工大学珠海学院 2020 届本科生毕业设计（论文）孔探技术在飞机发动机上的应用孔探技术在飞机发动机上的应用摘 要飞机动力装置是飞机能够起飞的基础，所以飞机发动机的安全是飞机安全的关键。随着技术的发展，飞机发动机检查工具设备及方法变得多样化。目前航空行业都选择用孔探技术来检验发动机损伤，这项技术显著提高发动机检验工作的工作效率和便携性。孔探技术可以在不拆解发动机的情况下，检测出发动机内部损伤，避免对结构复杂精细、价格高昂的飞机发动机造成不必要的损伤。本文可分为八章。第一章主要阐述论文的背景意义，了解孔探技术的原理、发展历程；第二章主要阐述了民用涡轮风扇发动机的基本工作原理和结构特点；第三、四、五章，主要是以第二章为基础，分析了发动机核心结构的常见损伤，了解孔探技术如何应用在飞机发动机的核心结构，并以中国南方航空较常用机型的孔探工作为例子分析如何通过孔探技术检测出飞机发动机内部损伤；第六章讲述孔探工作前后不可缺少的步骤--孔探堵头的拆装第七章主要阐述孔探设备的不足和未来发展方向，第八章对全文进行总结。关键词：孔探技术 飞机发动机 核心结构 内部损伤I北京理工大学珠海学院 2020 届本科生毕业设计（论文）Application of borescope technology in aircraft enginesABSTRACTAircraft power plant is the foundation of aircraft to take off, so the safety of aircraft engines is the key to aircraft safety. With the development of technology, aircraft engine inspection tools and equipment and methods become diversified. At present, the aviation industry has chosen to use borehole technology to detect engine damage, which significantly improves the efficiency and portability of engine inspection. The technology can detect the internal damage of the starting motor without disassembling the engine, so as to avoid unnecessary damage to the complicated and expensive aircraft engines.This paper can be divided into eight chapters. The first chapter mainly expounds the background and significance of the paper, and understands the principle and development course of the te...
