Searching for two optimal trajectories: A study on different approaches to global optimization of gravity-assist trajectories that have a backup departure opportunity

In interplanetary space missions, it is convenient to have a second departure opportunity in case the first is missed. Two distinct approaches to minimizing the maximum of the two Delta-V budgets of such a trajectory pair, are developed. The first (‘a priori’) approach optimizes the variables of both trajectories at once. The second (‘a...

Development of a Low-Thrust Earth-Centered Transfer Optimizer for the Preliminary Mission Design Phase

Develop the basis for a TU Delft Astrodynamics Toolbox (Tudat)-based software tool that comprises the fundamental functionalities required in order to optimize low-thrust Earth-centered orbit transfer trajectories for the preliminary mission design phase. Motivation: contribution to Tudat and facilitate case studies for the MicroThrust consortium.

A Multidisciplinary Optimization of Composite Space Enclosures

A design methodology for composite space enclosures was generated. As a result a panel of an electronics housing structure, as part of a general satellite traversing both GEO and LEO, was designed and optimized. A mass saving of 18% was achieved over a conventional aluminum panel, while assuring structural integrity for acceleration loads,...
