چکیده
Manufacturing of aero-engine components has been improvised over the years, commensurate with technological developments in the aeronautics sector. Compressor blade plays a vital role in an aircraft engine and flaws in its production can have adverse impacts on the performance of an aero engine. Despite technological advancements, many defects arise in these single crystal blades, which are manufactured by investment casting. This paper presents the developments in the manufacture of compressor blades and quality control inspection checks on them, by performing Non Destructive Tests (NDT). Metallurgical observations furnish better explanations on the developments in blade manufacture from conventional casting to additive manufacturing Keywords— Defect analysis, Super alloy, Dye penetration, Metallurgical inspection, Quality control, Additive manufacturing

Effect of aging and manufacturing tolerances on multi-stage transonic axial compressor performance
The Axial compressor is an integrated part of a gas turbine. The central part of compressors is its blades. Blade aerodynamic has a significant effect on compressor performance. Because of the adverse pressure gradient in the compressor, any deviation in the blade profile has a significant influence on the flow field as well as the compressor performance. During the manufacturing and operation ...
