Comparing the launch vehicle multidisciplinary design optimization frameworks

The main aim of this paper is introducing the launch vehicle multidisciplinary design optimization frameworks and also considering the performance of them (aspects of processing time and accuracy). Recently, two multidisciplinary design optimization frameworks are applied for optimizing launch vehicles are Multidisciplinary Design Optimization (MDO) and Holistic Concurrent Design (HCD). The first framework is developed based on Multidisciplinary Design Feasible (MDF) and the second one is established the fuzzy rule set based on designer's expert knowledge with a holistic approach. For assessment of performance the frameworks from time and accuracy aspects utilized the result of applying the frameworks on existing launch. The achieved results have shown the more accuracy in MDO and less processing time in HCD frameworks. That is noticed the MDO framework is developed in scientific literature and the HCD framework has not developed yet. Finally, the MDO and HCD methodologies are recommended to apply the multidisciplinary problems.
