.... A substantial increase in gas turbine engine performance, meaning increased power output and reduced specific fuel consumption, can be achieved by increasing the maximum allowable turbine inlet temperature. Subsequently, the majority of gas turbine engines are equipped with turbine blade cooling systems...
