The use of high-performance gas turbine engines has increased fuel costs making it essential for maintaining high working efficiencies of the engines. It is important to understand the basic design and aerodynamic principles regarding gas turbines. The factors that affect deterioration include the temperature control on the materials, rotor speeds and the stress levels, and the fluid dynamic characteristics that include, choking, dissolution, stall, and infuse. To attain sufficient thermodynamic efficiency, there is a necessary need for heat to be added at high temperatures (Meher-Homji, Chaker, and Motiwala, 2001). Accordingly, there shall be a mechanism for cooling to be included. The cooling characteristics can in turn affect the complete thermal efficiency of the engine. For that reason, the losses that culminate in the cooling flow can have detrimental effects causing a cycle penalty. Thus, several forms of deterioration can alter the cooling flow and the overall working efficiency of the gas turbine.
