An evaluation is made of the development status and consequentiality of unsteady flow-simulating CFD techniques applicable in advanced gas turbine compressor and turbine stage design. The maximization of aircraft gas turbine thrust/weight performance and reliability while minimizing acquisition and maintenance costs fundamentally depends on the ability to anticipate the effects of unsteady aeromechanical phenomena. Attention is given to blade flutter and forced vibration, stator/rotor interactions, flow instabilities and distortions, and the evolution of CFD techniques to date. 26 refs.
