Introduction to Project Area Turbine Technology Esa Utriainen

A Gas Turbine A tough environment… § High power density, 340 k. W / blade 1 for SGT 800 § Centrifugal load 32000 G, Blade 1 0, 8 kg becomes 26 ton in the engine. § High pressure and temperature, more than 1400 C @ 20 bar, Vane 1 inlet § Sensitive materials (900 C), every 10 -15 C increase equals halving the lifetime of the blading component Confidentiality notice Page 2 23 April 2009 Esa Utriainen
