Abstract
The present invention includes an intercooled cycle gas turbine. The intercooled cycle gas turbine is supercharged to improve performance. Pereformance is defined in terms of thermal efficiency and mass specific power, the turbine defining a cycle with a peak cycle pressure and a peak cycle temperature. The turbine includes an intercooler for intercooling the turbine, wherein placement of the intercooler within the cycle divides the cycle into a first compression stage and a second compression stage. The intercooler placement r=1/2 ln P.sub.super /ln(P.sub.peak /P.sub.super). The first compression stage and the second compression stage have an unequal pressure ratio.
