Abstract
The initial turbine stage design by . GTRE for their GTX engine had some scope for improvement ,in performance with regard to surface loading distribution . This aspect was required to be looked into through this sponsored project by GTRE . The cooled rotor blade profiles designated as P-27/GTX-35 (Scheme 8) were redesigned to relieve the excessive forward loading of the existing design and to achieve moderate diffusion . .! along the suction surface . The redesign and modification of these blade profiles were carried out through an iterative procedure using both design and analysis solutions based on singularity method . The redesign of turbine blade was carried out at tip, mean and hub sections . Blade, parameters like pitch, chord, throat, inlet and outlet flow angles were maintained more or less same as that of the given blade profile . Blade camber, stagger and thickness were allowed to vary to get the required velocity distribution . The redesigned tip and mean profiles showed an improvement in velocity distribution . The hub profile was not modified_ but only reoriented at reduced stagger and analysed theoretically . This work was sponsored and funded by GTRE, Bangalore for the development, of their turbine stages
