Profil: SQ
Schwerpunkt: SQ

The topic focuses on electro winning of metals and alloys from a typical Martian mineral, regolith, and the production of oxygen as a byproduct, without emitting greenhouse gasses or using fossil
fuels in any phase.
The following tasks are proposed for this Master's project:
1. Investigating various available regolith-like samples.
2. Systematic preparation of regolith pellets using the pressing-sintering method.
3. Characterization of the pellets in terms of porosity, morphology (SEM), mechanical (micro-hardness) and electrical (conductivity) properties.
4. Usage of an already existing set-up for high-temperature molten salt electrolysis and the self-prepared pellets for electrowinning, focusing on the impacts of the pellet-type and electrolyte composition on the results.
5. Characterization of the samples after the run using XRD analysis in order to determinethe current efficiency

Perform a market analysis regarding available technologies and concepts for large scale (e.g. upper stages, decommissioned satellites) space debris removal. Perform a techno-economical assessment (e.g. technical complexity, development time, project cost) and identify most promising approach for future removal technologies. Perform a mission design (Phase A level) of the selected concept (incl. system budgets) for a representative removable object.

A system design study shall be performed for a Mascot-type of landing system. This includes basic tasks for generating a 3D design, definition of the system architecture, investigation of the main subsystems and functionalities, calculation of the key performance parameters etc.

The main tasks include:

The team should organize itself as a design team with dedicated responsibilities per person. The system should be described using Model-Based System Engineering Methods. Expected outputs are a list of Requirements, 3D CAD, the System Model, dedicated (performance) analyses on conceptual level.

The Trajectory Analysis of a launch vehicle is an integral part of the mission. Not only does it deliver information about apogee but also about estimated landing sites, both valuable information for mission planning ans safety considerations. Launch sites need this information to verify if the launch vehicle meets their safety rules and wether it is feasible to launch from their site.

As a case study, the Transcendence rocket is a launch vehicle designed by ASTRA e.V. Bremen with a target apogee of 100km (the Karman line). The hybrid rocket is subject of this trajectory analysis and the results will be used in launch site applications in the future.

The Objectives of this Master project are:

1.) Analysis of the Trajectory of the Transcendence rocket with 6 degrees of freedom
2.) Evaluation of different scenarios and conditions of launch
3.) Interpretation of the landing sites with statistical evaluation
4.) Recommendation on design changes for optimization of the trajectory
5.) Summarizing the results in a report

The data on the launch vehicle will be provided by ASTRA as well as access to the ASTOS program. The design of the nosecone, the fins and their placement can be revised during the project in order to optimize the trajectory.
