Abstract : Modern aero engine concepts set very high technology standards for the component design. This is particularly true for turbines getting smaller in an increasingly hot environment. Precise control of the air system, the clearances and the deformations of the hardware become on important contributor to the overall performance and the life of the turbine. This situation suggests attempting an integrated approach to the aero/mechanical design. Analytical and experimental experience from an advanced technology gas generator programm is used to define the requirements on the engineering sciences involved. Some aerodynamic, performance and cooling problems to be solved in a common approach with the mechanical design for radial clearance control, hot gas path sealing and life are discussed. Attention is drawn to the interactions between these individual aspects of the design.
