TOWARDS SUSTAINABLE SPACE
THRUSTME IN A NUTSHELL
Constellations of miniaturized satellites in low Earth orbit are the future of global connectivity and real-time Earth monitoring. ThrustMe enables this new space industry to be economically and environmentally sustainable by developing and commercialising standalone, fully integrated space propulsion systems together with value-added engineering services for these next generation satellites.
ThrustMe was founded in early 2017, leveraging more than 10 years of applied and fundamental research at one of the most prestigious research centres in France. Scientific rigour is one of the core values of ThrustMe; accelerating innovation by combining low-end-disruption of traditional space technologies with breakthrough inventions inspired from f.ex. the semiconductor industry.
Ion thrusters are promising for SmallSats
BUT there are technological hurdles in miniaturization due to their need for a separate neutralizer and gaseous propellant – We solved this problem using clever, innovative solutions
CLASSICAL ION THRUSTERS
In an ion thruster, ions from a gas discharge (a plasma) are accelerated via static electric fields using a set of biased grids. This ion beam generates thrust and its high velocity ensures a high Isp and therefore low propellant consumption. To avoid beam stalling and charging of the spacecraft, the positive ion beam needs to be neutralized by electrons in the downstream space. This is achieved with a separate neutralizer. Power, typically obtained from solar panels, is fed to the various parts of the system via a power processing unit (PPU). The propellant, typically xenon, is fed into the gas discharge chamber and the neutralizer.

OUR INNOVATIVE SOLUTION
Our solution is a novel ion thruster operating with solid propellant that combines technologies from the space and semiconductor industries. The acceleration grids are biased with radiofrequency (RF) voltages across a capacitor. Due to the different mass of ions and electrons the plasma acts as a diode and the capacitor charges up (self-biases). The resulting DC voltage accelerates ions continuously while electrons exit during a short period within the RF cycle. This leads to significant simplification and advantages over classical ion thrusters, while still keeping similar or even better performance. The use of a solid propellant with a high vapor pressure (such as iodine) removes the need for high pressure storage and complex valves for flow control.
Our patented solution solves a number of key problems

“Access to space and the digital revolution have both contributed to the economic and societal changes we are living today. In return, these changes are accelerating the demand for space and thus generating disruptions in space technologies and systems. Among those disruptions, ThrustMe is one of the most innovative and promising start ups in Europe”Jean-Jacques Dordain
