1 PhD Research position on Integrated Solar System for Small Spacecraft in Netherlands | Delft University of Technology (TU Delft)

The proposed research stems from a new concept of solar thermal systems capable of co-generating electric power, thermal power and propulsion for a small-sized spacecraft, optimally integrating these multiple functions into an ultra-efficient energy conversion system. The newly conceived integrated system comprises one or more solar concentrators, transferring thermal power to the working fluid of a high-temperature Organic Rankine Cycle (ORC) turbogenerator, and one or more thrusters.

Preliminary assessments demonstrated the feasibility of the proposed concept for small spacecraft in the range of 100 to 350 kg, namely to electric power levels in the order 100 We. With the expertise available at our faculty, we envisage scaling the technology down to the power level of 10 We, paving the way to a large number of innovative applications within the space sector. The main deliverables of the research are: 1) Study of the solar thermal propulsion system and the solar collectors; 2) Study of the aspects associated with thermal energy storage, management, and transfer; 3) Study of micro-turbines in the power range 10-100 We; 4) Design and optimisation of the full system; 5) Manufacturing and test of the most critical components of the system at the required miniaturisation level. To model the system and its components we will use our specialised software suite.

The PhD candidate will be jointly supervised by Dr. Angelo Cervone (SSE) and Dr. Matteo Pini (P&P). The PhD student will work at TU Delft, and will participate to the regular meetings with the project stakeholders. The candidate will have the opportunity for short stays in collaborative institutions.

Requirements

Applicants should have a Master degree from a renowned institution in mechanical, aerospace, energy or control engineering, or another technical area deemed relevant for the proposed research programme. Strong motivation, creativity, and proactivity are required. The PhD position is focused on analytical and modelling work, with a final part centred on laboratory experiments. Capacity for complex theoretical interpretation of results is required. Good interpersonal communication skills are necessary in order to properly integrate into the fairly large, diverse and international team. Applicants must be fluent in English (English supervision).

Conditions of employment

The PhD student will be appointed for a period of four years. After the first year an evaluation will take place. The TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers childcare and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.

As a PhD candidate you will be enrolled in the TU Delft Graduate School. TU Delft Graduate School provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and a Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills.
