The Multidisciplinary Design Optimization of a Reentry Vehicle Using Parallel Genetic Algorithms

The purpose of this paper is to examine the multidisciplinary design optimization (MDO) of a reentry vehicle. In this paper, optimization of a RV based on, minimization of heat flux integral and minimization of axial force coefficient integral and maximization of static margin integral along reentry trajectory is carried out. The classic optimization methods are not applicable here due to the c...

Grid Generation for Multidisciplinary Design and Optimization of an Aerospace Vehicle— Issues and Challenges

The purpose of this paper is to discuss grid generation issues and to challenge the grid generation community to develop tools suitable for automated multidisciplinary analysis and design optimization of aerospace vehicles. Special attention is given to the grid generation issues of computational fluid dynamics and computational structural mechanics disciplines.

A Unified Approach to Modeling Multidisciplinary Interactions

There are a number of existing methods to transfer information among various disciplines. For a multidisciplinary application with n disciplines, the traditional methods may be required to model ) ( 2 n n − interactions. This paper presents a unified three-dimensional approach that reduces the number of interactions from ) ( 2 n n − to n 2 by using a computer-aided design model. The proposed mo...

Optimization of Complex Mechanics Simulations with Object-Oriented Software Design*

The benefits of applying optimization to computational models are well known, but their range of widespread application to date has been limited. This work attempts to extend the disciplinary areas to which optimization algorithms may be readily applied through the development and application of advanced optimization strategies capable of handling the computational difficulties associated with ...
