Abstract

A new methodology for DFSS suitable for the design of a complicated multidisciplinary system such as a gas turbine engine is proposed. There are four phases in this methodology: define, analysis, MDO and verify. More detailed information of each of the four phases was introduced. The design of a diagonal impeller which is used in an aero engine was taken as an example to demonstrate the implementation process of the methodology. In the phase of MDO, computational fluid dynamics, computational structural mechanics simulation methods were used. The mathematic model of DFSS of the diagonal impeller was established and self developed DFSS software was used to solve the model so as to get longer fatigue life, lighter weight and higher aerodynamic performance. The results of the example indicate that the proposed methodology is efficient.
