In the past ten years there has been a dramatic increase in turbine inlet temperature in aircraft gas turbine engines. This increase has been made possible by the application of extensive air cooling to turbine parts. The attendent increase in turbine design complexity without an increase in engine design or development time has been made possible by the development of modern computers and computer programs. A computerized turbine automated design system (TADSYS) was developed at Pratt and Whitney Aircraft, which makes extensive use of computer graphics, to meet the needs of modern turbine design.
