防除冰电加热组件胶粘缺陷分析和更换技术

Research on Adhesive Defect Analysis and Peplacement Technology of Anti-deicing Electric Heating Components

复合材料桨叶防除冰电加热组件为薄壁多层粘接结构。分析了激光散斑和超声成像检测技术在电加热组件内部胶粘缺陷检测中的能力,并设计出相应的检查工装或设备;创新设计了一套专用的防除冰电加热组件更换修理方法,用包铁剥离专用工具夹持包铁并利用杠杆原理对包铁进行剥离;建立电加热组件更换修理的流程标准体系,编制了专用的电加热组件更换工艺指导文件,巩固电加热组件更换修理质量。

Aiming at the thin-walled multi-layer bonding structure of the composite blade anti-deicing electric heating composite,the detection ability of laser speckle and ultrasonic imaging detection technology in the internal adhesive defects of the electric heating component was analyzed,and the corresponding inspection equipment or equipment was designed.A set of special anti-deicing electric heating component replacement and repair method was innovated.The iron cladding stripping tool was used to clamp the iron cladding and peel the iron cladding by using the Du-bar principle.Established a standard process system for the replacements and repair of electric heating components.
