Integrated Multidisciplinary Design of High Pressure Multistage Compressor Systems (la Conception integree des compresseurs multi-etage a haute performance)
Abstract
This Lecture Series covers the recent advances in the process of performing integrated design of high performance multistage compressors. The purpose is to broaden the compressor designer's understanding beyond traditional fluid dynamics to include the multidisciplinary systems approach required by modern gas turbine engines for longer life, lower acquisition and maintenance costs. The design process requires an optimization of the entire machine, which may be significantly different from the best aerodynamic design of each stage or blade row. In addition, many modern engines are simultaneously increasing compressor performance, and reducing machine length, which reinforces the fluid and structure interactions. Finally, in order to reduce both production and maintenance costs, manufacturing constraints have to be taken into account in the initial phase of the design process. The Lecture Series underlines the role of Computational Fluid Dynamics, as well as solid mechanics and vibration simulations. The need for compressor designs to consider and model mechanical interactions and manufacturing concerns will be a central focus. The subjects to be covered are: (1) Flow simulations with special emphasis on three-dimensional computations and on the stage stacking and interactions in multistage compressors. (2) Modelling the fluid structure interactions. (3) First order manufacturing constraints and requirements. This Lecture Series, sponsored by the Applied Vehicle Technology Panel (AVT) of RTO, has been implemented by the Consultant and Exchange Programme.
