Structural Analysis of Micro Compressor Blades

Abstract

A micro turbine used in refrigerator, generator; air drier. A micro turbine – compressor assembly being small in size as compared to large turbine has less weight which reflects on pressure ratio. In our paper we are analyses the compressor shaft and blade of a micro compressor under various loading condition and study the effect of stress distribution over the blade at various speed and shapes. Withstanding of compressor blades of gas turbine for the elongations is a major concern in their design because they are subjected to high axial, tangential, centrifugal forces. There are several projects summarize the design and analysis of gas turbine compressor blade by usingvarious power full finite element software. The present work includes the structural analysis of compressor radial impeller blade designed for small 50kW gas turbine application using solver fluent, Ansys13.0, which is powerful Finite element software. Effect of different material, Titanium, aluminum at the various rotational speed.
