Our Research in CubeSat Propulsion

• We Research focus on the the Theoretical, Mathematical, Numerical and Experimental aspects of electric Propulsion thrusters.

INTOSPACE project coordinated by SIA ASPC LAB with other EU member companies and research agencies, proposed the investigation, design, manufacturing, integration, and testing of an innovative heatless cathode based on carbon nanotube arrays for the gas ionization to be coupled with a 85 mN Hall-Effect Thruster fed by a cheaper Krypton propellant. In fact, CNT Field emission cathodes (FECs) provide a promising alternative, due to the following benefits:

(i) No propellant is consumed in FECs, and therefore the whole system-specific impulse can be increased;

(ii) Reduction of the propulsion system power requirements;

(iii) Fast starting time;

(iv) Reduction of cathode ordinary wear

Key Design features :

• Low-cost microthruster for CubeSat applications

• Ease in producibility via 3D printing

• Flexibility in installation within the CubeSat of 3U with available volume to payload mass

• Possible to modulate the thrust and direction of thrust through the ignition of one or more micro rockets, at different positions that depend on the mission requirements.
