T4i is active in two parallel frames, electric and chemical propulsion systems for small satellite mobility in space and hybrid-rocket for low- cost access to space.
In the frame of electric thrusters, T4i has developed the REGULUS propulsion systems’ family, exploiting its extensive expertise on the Magnetic Enhanced Plasma Technology.
REGULUS-50 is the smallest thruster within the family and is a complete and innovative 1.5U electric propulsion system suitable for micro and nanosatellite platforms from 6U to 150kg. REGULUS-50 is the first Italian propulsion system based on solid Iodine and is currently performing its IOD mission. REGULUS-150 and REGULUS-500, based on the same technology, are the scale-up version of REGULUS-50 in power (150 W and 500 W respectively) and performance.
In the frame of chemical thrusters, T4i is developing monopropellant thrusters in the range 1-500 N, and a bi-propellant thruster using kerosene in the range 1- 500 N (scalable to few kN). Today these technologies
reached TRL 5/6 depending on the application. T4i uses green propellants only, like the HTP. In the frame of hybrid rockets, T4i is developing innovative hybrid systems based on paraffin wax.
