在发动机维修中,热端部件检查是一项标准严、难度大、风险高的仅次于翻修的深度维修工作,而部件装配又是热端部件检查工作中难度最大、风险最高的环节,通过对FJ44-1A涡扇发动机热端部件装配工作的研究和维护经验的积累,本文总结了FJ44-1A涡扇发动机热端部件装配的关键方法,为有效降低维修差错风险、避免重大经济损失,保证飞行安全提供了技术支撑。 In the engine repair, hot-end parts inspection is a standard, difficult, high-risk second only to repair the depth of repair work, and component assembly is the hottest parts of the most difficult part of the inspection work, the risk of the most links, through This paper summarizes the key methods of assembly of FJ44-1A turbofan engine hot-end components. In order to reduce the risk of maintenance errors and avoid major economic losses, Flight safety provided technical support.
