The mission scenario has been based on three ion thrusters of the RIT-22 model, which is presently under space qualification, and on solar arrays equipped with triple-junction GaAs solar cells. After having designed the spacecraft, the orbit-to-orbit trajectories for both, a one-way SEP mission with a chemical sample return and an all-SEP return mission, have been optimized using a combination of artificial neural networks with evolutionary algorithms. Additionally, body-to-body trajectories have been investigated within a launch period between 2012 and 2015. For orbit-to-orbit calculation, the launch masses of the hybrid mission and of the all-SEP mission resulted in 2.05 tons and 1.56 tons, respectively, including a scientific payload of 246 kg. For the related transfer durations 4.14 yrs and 4.62 yrs were obtained. Finally, a comparison between the mission scenarios based on SEP and on NEP have been carried out favouring clearly SEP.}, language = {en} } @incollection{SchmitzWeber2007, author = {Schmitz, Philipp and Weber, Martin}, title = {Setze nicht alles auf eine Karte, diversifiziere!}, series = {Genial einfach investieren}, booktitle = {Genial einfach investieren}, publisher = {Campus-Verlag}, address = {Frankfurt a.M.}, pages = {104 -- 140}, year = {2007}, language = {de} } @article{VuStaat2007, author = {Vu, Duc Khoi and Staat, Manfred}, title = {Shakedown analysis of structures made of materials with temperature-dependent yield stress}, series = {International Journal of Solids and Structures. 44 (2007), H. 13}, journal = {International Journal of Solids and Structures. 44 (2007), H. 13}, isbn = {0020-7683}, pages = {4524 -- 4540}, year = {2007}, language = {en} } @misc{Engels2007, author = {Engels, Elmar}, title = {Sicherungseinrichtung mit einem ein leitf{\"a}higes Muster aufweisenden Sicherungsring : Offenlegungsschrift : DE102006019811A1 ; Offenlegungstag: 31.07.2007}, publisher = {Deutsches Patent- und Markenamt}, address = {M{\"u}nchen}, pages = {12 S.}, year = {2007}, language = {de} } @misc{Engels2007, author = {Engels, Elmar}, title = {Sicherungseinrichtung und Sicherheitskappe mit mehrlagigem leitf{\"a}higem Muster : Offenlegungsschrift : DE102006017506A1 ; Offenlegungstag: 18.10.2007}, publisher = {Deutsches Patent- und Markenamt}, address = {M{\"u}nchen}, pages = {13 S.}, year = {2007}, language = {de} } @article{Strohmeier2007, author = {Strohmeier, Andreas}, title = {Siedlungswasserwirtschaft}, series = {Bautechnische Zahlentafeln / Wendehorst, Reinhard ; Wetzell, Otto W.
