Abstract

The purpose of this article is implementation of upper stage design according to multistep sequential optimization design process for specific maneuvers with less mass in reality. In this method there are two optimization and design loops which are connected to each other in mass analysis. So all the output parameters in inner loop are used as input parameters of outer loop. In the inner loop, optimization control algorithm is used to optimize the target function, as for two control factors including thrust vector angle and thrust magnitude for putting upper stage into final orbit. In outer loop, subdivision is designed separately according to design matrix using input parameters from the inner loop. Design convergence is checked in mass analysis. Innovation of this article is the implementation of a fully systematic upper stages design. Also, a system-based method is provided by cooperation of human and machine (multistep collaborative design) which, in addition to SYSTEM DESIGN, discussed subsystem design such as orbital optimization and subdivision algorithms. Results of this design are verified according to the result of statistical analysis.
