Volume : II, Issue : VII, August - 2012 Optimization Of Gas Turbine Blades K.Chandrasekhar, M.Ananda Rao and B.Sudheer prem kumar Published By : Laxmi Book Publication Abstract : This study is part of research project concerning the development of High Pressure
turbine blades with advanced cooling systems. Due to the high gas temperatures
entering the turbine of the most recent aero-engines in general up to 2000 K at the
turbine inlet at 40 bars, a very efficient cooling system is required in order to maintain
the metal temperatures below the allowable limits. This means to use a certain amount of
"cold" air directly extracted from the compressor, with a significant negative impact on
the engine performance.
A novel methodology has been used to design the layout of the tip cooling nozzles of a
high pressure rotor blade turbine. The methodology used is through a complete CAE
approach, by means of a parametric CFD model which is run many times for the
exploration of several designs by an optimizer. Keywords : Article : Cite This Article : K.Chandrasekhar, M.Ananda Rao and B.Sudheer prem kumar, (2012). Optimization Of Gas Turbine Blades.
