A repair and overhaul methodology for aeroengine components

Microstructural and mechanical characterization of Ti6Al4V refurbished parts obtained by laser metal deposition

“…The material is mainly used in low pressure compressor engine blades, compressor spool, disc and airframes in the aerospace industries [1][2][3].…”

Transformation from manufacturing process taxonomy to repair process taxonomy: a phenetic approach

“…Non-destructive inspection techniques to detect cracks were employed (Diamanti et al 2005). Methodology for repair and overhaul of aero engine has been developed (Yilmaz et al 2010 peening technology has been employed for repairing (Kudryavtsev et al 2007). Repairing operation on different parts has been carried out (Desir 2001) but still in current scenario, no researcher is found successful in diminishing the dilemma between repair processes and manufacturing processes, for example, welding process is a joining process in manufacturing terminology but in repair terminology, welding is a material addition process to prepare surfaces which resulted in a situation where repairer are in no-man's-land.…”

Reverse modeling strategy of aero-engine blade based on design intent

“…Since each blade undergoes complex deformation within the range of design tolerance in the forming process [2], its nominal computer-aided design (CAD) model cannot be directly used for NC tool path generation. In addition, the repair process of serviced blade faces the similar challenge [3]. Reverse engineering (RE) technology has been widely recognized as a crucial role in the secondary NC machining.…”
