Advanced Space Propulsion CISAS Propulsion Group

In the framework of Helicon Plasma Thrusters, we developed theoretical models and innovative codes capable of simulating the electromagnetic interaction between radiofrequency antennas facing anisotropic media (e.g, plasmas).

We are currently applying this knowledge in the development of improved plasma sources for industrial and space applications, along with brand new concept antennas relying on 3D plasma current for radiating electromagnetic fields.

We perfomed several research activities in support of Aerospace Insutries (I.e Thales Alenia Space) in facing specific issues related to spacecraft operation. Particularly, we have good simulation capabilities of the following phenomenas: (i) Priming, (ii) Propellant sloshing with elastomeric bladder, (iii) Propellant management devices (PMD). We have also set-up specific test beds to test thruster priming, and to perform flight experiments on a sponge PMD. 

Research

Our group performs researches on four main fields: (i) Hybrid Rockets, (ii) Plasma Thrusters, (iii) Electromagnetics, and (iv) Propulsion Subsystems. In all of these fields we perform both theoretical/numerical activities and experimental activities. We are structured to carry out demanding, interdisciplinary research programs from paper to the final product, but also to perform limited, well defined technical activities in support to customers.

Regarding plasma thrusters, our activity is mainly focused on helicon plasma thrusters. We have been leading a consortium of 15 partners around Europe into the development of the first engineering model ever developed in the world of a helicon plasma thruster. Our focus activity is low power ( below 100W), however, recently we have started experimental activities targeted to 1 kW of electric power. 

Moreover, we also perform simulations in collaboration with other Univeristies and Research centers applying our Plasma code to the simulation of other thruster concepts or particle accelerators.  

On hybrid rockets, our activity is mainly focused on advanced hybrids, based on paraffin wax as the fuel.  

We have several research lines: (i) injection, (ii) combustion, (iii) stability, (iv) grain manufacturing and structural issues.

We have conducted several research programs. The most relevant one has led to the development of the largest hybrid rocket ever flown in Europe.
