The purpose of the ASCenSIon project is to develop a programme that focuses on several specific areas of cutting-edge space access research, particularly on launcher systems that are (partially) reusable and capable of injecting multiple payloads into multiple orbits. More than providing design concepts, the network aims to identify and advance critical technologies to prove a feasibility of these concepts. Fields of research and training include propulsion technologies and their reusability; Guidance, Navigation and Control (GNC); aero-thermo-dynamics of re-entry and safe disposal. A variety of technologies will be advanced, including hybrid rocket engines, electric pump feeding and advanced nozzle configurations. Both computational and experimental (cold-flow and hot fire) techniques will ensure an efficient process and reliable results. The reuse of propulsion systems demands an assessment of their durability. It will be conducted by numerical simulations, system analysis with EcosimPro/ESPSS and experimental test runs. The development and integration of wireless sensor networks will allow health monitoring of these critical subsystems. Moreover, novel GNC strategies and processes have to be developed for the whole mission trajectory. This includes solutions for optimised flexibility w.r.t. the orbital insertion conditions as well as dedicated descend trajectories and GNC missionisation for re-entry. The models will cover various recovery concepts and the support of multiple landing sites. This requires an extensive examination of the aero-thermo-dynamics during re-entry as well as of the interactions between stage recovery and propulsion system layout. Ecological and economical sustainability will be addressed as new payload concepts including large constellations increase the demand for safe disposal and space debris mitigation to ensure an open access to space in the future. Furthermore, the utilisation of so called green propellants will be investigated.

About the host organization
Technische Universität Braunschweig (TUBS) is the oldest university of technology in Germany (founded 1745) and it is ranked among the top engineering universities in Germany. It has about 20,000 students, 2,200 academic staff, 1,500 administrative staff members. The Institute of Space Systems (IRAS) performs various activities in the field of space engineering. Since 1970, a primary subject is the development of advanced computer programmes for the orbital mechanics of satellites and the practical application of this software for space mission planning and satellite re-entries. IRAS has performed pre-warning calculations for the German Government in case of several risk-object re-entries and is participating in the annual re-entry campaigns performed by the Inter Agency Space Debris Coordination Committee (IADC) on behalf of DLR. IRAS has expanded its research to innovative docking mechanisms, GNC algorithms, CubeSat development, reliability assessment of spacecraft and robotics. Thus, the research focusses on AOC of spacecraft, docking and active space debris removal using servicer spacecrafts that enable a controlled re-entry. Innovative docking mechanisms like adhesive bionic materials are used as well as multibody dynamics. These can be validated with a comprising test environment consisting of an air-bearing table, a robotic arm and several test bodies. This work also benefits from the space debris research that provides risk analyses and failure probabilities for spacecrafts in earth orbit. A further work group for new systems and technologies allows research areas like propulsion systems for small satellites and probes as well as utilization of local research and science of the lunar environment.

Your PhD project
The PhD programme is offered by the Department of Mechanical Engineering at TU BS. The ESR will focus on reliability concepts of reusable launcher systems. The work will be based on existing methods of satellite reliability and will incorporate aspects from space situational awareness and from the space debris environment. The candidate can build upon the previous research of the Institute of Space Systems on space debris modelling and end-of-life concepts.
Determining the exact place and time of re-entries is still challenging because different uncertainties need to be considered. In today’s launcher development, very conservative methods like combinatorial reliability are applied for reliability calculation. This frequently leads to masses and costs higher than necessary.
- Developing a new reliability model for rocket flight with special focus on re-entry by transferring existing reliability methods to launcher concepts defined
- Implementing a software or software component that can determine re-entry prediction for new rocket concepts based on mission designs investigated
- Considering space situational awareness aspects, such as propagation with uncertainties, the space debris flux, and collision probabilities within the software
- Investigating new concepts that enhance or allow a safe disposal, such as green propellants, passivation, enhanced break-up or advantageous orbits
- Sustainable and reliable rocket concepts based on most suitable technology and mission concepts
- Verification of their safe disposal by reliability model and precise trajectory software
Two secondments are foreseen to:
- ESA Space Debris Office in Germany, for a duration of 4 months, to perform research in SOTA observation, orbit determination & prediction, error estimation and space debris cataloguing
- D-Orbit in Italy, for a period of 6 months, to perform research in investigation of decommissioning / commissioning solutions and constellation deployment strategies Profile
- You will be working within our international group of > 30 researchers with experience in a broad range of sciences
- You will get in contact with the other members of this international consortium and will benefit from the joint training platform to develop skills necessary for developing a thorough understanding of space transportation systems
- You will be employed by the host organization for 36 months
- A competitive salary plus allowances. Moreover, funding is available for technical and personal skills training and participation in international research events
- You will benefit from the well-structured training programme offered by the host organization and the consortium
