Examination of Aerofoil Blade Fabricated by Additive Manufacturing Process

Abstract

ADDITIVE MANUFACTURING is a method which involves formation of a physical object from a virtual 3D model, usually by numerous successive thin layers of a substance. Traditional design and manufacturing processes have a variety of undesirable limitations in many applications, including expensive tooling, fixtures and assembly of complex parts. However, as in machining, the subtractive manufacturing processes can result in the loss of up to 90% of the original material block. On considering the accuracy, functionality, high end products, material used and typical layer thickness FDM is the most appropriate and adaptive method for manufacturing the 3D printing objects. The Scope of the work is to design the 4515 airfoil to work without fail under extreme conditions. Analyzing the airfoil at a given inlet speed of 138 m / s in ANSYS FLUENT and a structural analysis to determine if it is structurally stable under extreme conditions using ANSYS STRUCTURAL ANALYSIS. In this work ,the analysis is carried out by stream of fluid (air) over NACA 4515 Airfoil and its structural analysis. The values obtained are within the desired limits according to NACA, hence the design is structurally safe.
