Global and Local Multidisciplinary Design Optimization of Expendable Launch Vehicles

Multidisciplinary Design Optimization of Solid Launch Vehicle Using Hybrid Algorithm

A new approach is proposed incorporating heuristic optimization algorithm with a switch to a local search algorithm for the multidisciplinary design of solid launch vehicle at conceptual level. Heuristic optimization algorithms such as Genetic Algorithm often may locate near optimum solutions at the expense of large function evaluations. Local search algorithms including both gradient and non g...

Economic Model of Reusable vs. Expendable Launch Vehicles

It is generally assumed by the community that reusable launch vehicles will dramatically reduce launch costs because you don’t “throw away the vehicle” every time it is used. However, this is usually taken as an element of faith, without any substantive analysis to support the conclusion. The example of the Space Shuttle, originally sold to Congress on the basis of dramatically cutting launch c...

Study of a Global Design Space Exploration Method for Aerospace Vehicles

In the early stages of the design process of aerospace vehicles, the search for optimal configurations encompasses a broad range of possibilities, and the use of local optimization tools may risk missing the best designs. Therefore, global optimization methods are attractive for the early design stage. Unfortunately, global design optimization usually requires the evaluation of a very large num...
