3D Modelling and Analysis of Micro Gas Turbine Compressor Blade
Abstract—Microturbines can be utilized in refrigerator, generator, air drier, etc., Micro turbine being small in
size as compared to large turbine, such that less weight which reflects on pressure ratio, low
cost and easy maintenance. Design and analyze of the micro turbine compressor blade is
carried out in this thesis. With different material and rotational speed, compressor blade of the
micro turbine is analyzed. A 3D Structural design of microturbine generating 120 KW of output
power is modeled in Solidworks. Based on the given microturbine output power, the dimensions
and physical properties of the compressor blade were calculated. Titanium, Aluminium and
Stainless steel alloys, this materials effect on compressor blade are found out by carrying stress
and modal analysis. Microturbine systems claimed many advantages over reciprocating engine
generators, such as higher power to weight ratio, low pollution and having few moving part.
Microturbines have many advantages, such that it may be designed with foil bearings and aircooling
operating without lubricating oil, coolants or other hazardous materials. Microturbines
are quicker to respond to output power requirement and also more efficient. Microturbines also
have more efficiency at low power levels than reciprocating engines. The variation of rotational
speed is a representation of various operating conditions, depending on the required output. By
analysis software ANSYS 12, stress and modal analysis are done.
