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.
The ASCenSIon consortium includes Technische Universität Dresden, German Aerospace Center, Sapienza Università di Roma, ONERA, Université libre de Bruxelles, Hochschule Bremen, Università di Pisa, Technische Universität Braunschweig, Politecnico di Milano, DEIMOS Space, ArianeGroup, ESA, AVIO, OHB, D-Orbit, SpaceForest and Telematic Solutions.
About the host organization:
Università di Pisa (UniPi) is an ancient and prestigious academic and research institution with a long-standing tradition in industrial engineering and hard science, such as physics and chemistry. In 2013, the University of Pisa finished with USR (which is also part of the consortium) in the first place among the Italian universities, according to the Academic Ranking of the World Universities. The administrative staff comprises 1.900 employees. UniPi has 50.000 students and an additional 3.500 doctoral students. UniPi participates with a team of researchers coming from the Aerospace Engineering Division of the Department of Civil and Industrial Engineering (DICI, www.dici.unipi.it). At DICI, major areas of study and research in aerospace engineering include space systems, space mission analysis and design, flight mechanics, fluid dynamics and aerodynamics, aerothermodynamics, chemical and electric rocket propulsion, air-breathing propulsion, structures and materials. To this purpose, the Aerospace Engineering Division runs a broad set of dedicated facilities and specialized laboratories. Research activities are carried out in close collaboration with several intergovernmental organizations, prestigious universities, and aerospace and mechanical companies. (www.unipi.it)
Your PhD project:
The researcher will be in charge of the assessment of design solutions for green expendable upper stages. In particular, the research will start with the identification of relevant mission profiles of future launchers and the corresponding requirements for their green expendable upper stages compliant with the space debris mitigation guidelines. Then, after doing the preliminary design of the upper stage with focus on attainable propulsive performance and affordable envelope and mass budgets, the ESR will carry out the detailed design of the propulsion system of the selected upper stage(s) with focus on most critical components.
The ESR will be enrolled in a PhD course at Università di Pisa and will be asked to: attend a list of local and network-wide training activities during the project (e.g. lectures, workshops, seminars, conferences, etc.); attend language courses in English and in Italian; actively disseminate the research results (e.g. publications in peer-reviewed scientific journals and scientific presentations at international conferences); perform two secondments in prestigious institutions to widen the skills on green propulsion.
One ESR is fully dedicated to the green propulsion system design for upper stages due to the complexity of upper stage design aspects including the development of green propulsion systems as well as the adherence to safe disposal requirements and novel GNC solutions for injecting multiple payloads to different orbits.

- Detailed design of the propulsion system of the upper stage powered by liquid green propellants with focus on most critical components
- Definition of the requirements for upper stages of future launchers
- Recommendation of green propellant technologies for future substitution of current upper stage powered by toxic propellants
- Detailed design of the down-selected liquid green propellant technologies for the upper-stage.
- Ground testing of the most critical components of the selected upper stage propulsion system (e.g. monopropellant and bipropellant thrusters and/or their components, tanks, etc.)
Two secondments are likely foreseen to:
- DLR, for a duration of about 4 months, to work on the development of hypergolic bipropellant combination
- Hochschule Bremen, for a duration of about 4 months, to work on the optimisation of an ethanol injection system.
- 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 the maximum duration compatible with the ASCenSIon Project (most likely 31.5 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 form the well-structured training programme offered by the host organization and the consortium
- You will participate in international conferences and secondments to other organisations within the ASCenSIon network and in outreach activities targeted at a wide audience
The selected candidate will be appointed a temporary contract, salary will be in line with the funding schemes of MSCA action, and in accordance with Italian rules and regulations within this regard and Country specific requirements, as stated in the Grant Agreement and Guide for Applicants. Monthly salary (living allowance + mobility allowance) will be of approx. 4.000€ (gross amount), allocated following Italian specific contract conditions for MSCA candidates. Family allowance will be granted upon specific conditions.
