Design of a Semi-Empirical Tool for the Evaluation of Turbine Cooling Requirements in a Preliminary Design Stage

There is an everlasting demand for higher cycle efficiencies in gas turbine engines. One way to obtain a higher efficiency is to increase the overall pressure ratio (OPR) of the engine. In order to benefit from the efficiency increase whilst maintaining the same specific gas power, the turbine inlet temperature (TIT) has to increase with it....
