Abstract
We have developed the new optimization method called Stochastic Process Optimization Technique (SPOT). In this paper, integrated optimization of SSTO for two different engines was performed. As a result, similar flight path with different airframe configuration was obtained. In addition, different flight path with similar airframe configuration was obtained as temporary optimum solutions in optimization process. These transitions of optimum solution indicate the influence of SSTO's engine performance on its airframe configuration and flight path through the integrated optimization. The necessity for the integrated optimization for SSTO was shown. Simultaneously, the integrated optimization ability of SPOT was shown.
