This paper presents the results of experimental investigations on an additively manufactured AlSi10Mg propeller blades. Additive Manufacturing (AM) is a merging manufacturing process that is based on adding layers to form a one-piece 3D component shape. While this process demonstrates several benefits, there is a challenge to fully implement AM into the metal industry since other portions of engineering principles like testability, reliability, integrity, etc. are not addressed. The presence of inherent defects in aircraft propellers may cause catastrophic failures when subjected to cyclic loading and impact. This study evaluates embedded defects that were drawn by SolidWorks software and printed by powder bed fusion (BPF). The X-ray Computed Tomography (CT) and Phase Array Ultrasonic Testing (PAUT) were used to assess for testability and reliability of these methods in comparison.

摘要

This paper presents the results of experimental investigations on an additively manufactured AlSi10Mg propeller blades. Additive Manufacturing (AM) is a merging manufacturing process that is based on adding layers to form a one-piece 3D component shape. While this process demonstrates several benefits, there is a challenge to fully implement AM into the metal industry since other portions of engineering principles like testability, reliability, integrity, etc. are not addressed. The presence of inherent defects in aircraft propellers may cause catastrophic failures when subjected to cyclic loading and impact. This study evaluates embedded defects that were drawn by SolidWorks software and printed by powder bed fusion (BPF). The X-ray Computed Tomography (CT) and Phase Array Ultrasonic Testing (PAUT) were used to assess for testability and reliability of these methods in comparison.
