Van Oostrom, J. (author)In a previous study, the optimal re-entry trajectory of Hyperion-2 has been derived. The mission of the vehicle is to measure hypersonic boundary-layer transition, a phenomena in which the laminar boundary layer turns into a turbulent boundary layer. This is an important feature in hypersonic flow to investigate, as it introduces peak heating...master thesis 2015

Roegiers, T.G.R. (author)Since the development of the exponential sinusoid for low-thrust trajectory design by Petropoulos and Longuski [2004], more shape-based methods have emerged that ease up the work of a mission analyst. These methods are the ideal tool to generate a quick and almost complete overview of a large search space and are useful for producing first...master thesis 2014

Perdeck, Matthias (author)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...master thesis 2018
