Developpement d'un systeme d'optimisation multidisciplinaire flexible et adaptable a differentes methodes de decomposition.

摘要

Preliminary Multidisciplinary Design Optimization (PMDO) project was initiated to reduce aircraft engine concept development time. It addresses the development and implementation of the Multidisciplinary Design Optimization methodology in the concept stages of the complex gas turbine design process. These initial phases encompass a wide range of coupled engineering disciplines and make the largest influence on the final product configuration. The PMDO is a software tool intended to integrate existing analysis tools, decompose coupled multidisciplinary problems and, therefore, allow optimizers to enhance preliminary engine designs. It should allow engineers to quickly obtain sound preliminary designs and to explore a wider design space.; Among the requirements for PMDO System is the ability to handle any combination of engine sub-components. Moreover, end users are not familiar with decomposition and optimization issues. Therefore, the PMDO System must be user friendly, flexible and automate as much as possible the decomposition of any design optimization problem. (Abstract shortened by UMI.)
