REGULUS

REGULUS is T4i first Electric Propulsion System in the market already tested in space. REGULUS is a robust, versatile, and cost-effective propulsion system for small satellite platforms and nanosatellite deployers.

OUR background

We are working on magnetically enhanced RF plasma technology propulsion systems since more than 10 years. Starting from the sketch, we designed, manufactured and tested our plasma systems, solving the stoppers for its maturation.

10+ years of experience

capabilities

We carry out research and development activities
through a combined experimental investigation.

We design, develop and test PPUs, RF networks, plasma sources and plasma thrusters.
We design, develop and optimize numerical codes for full thruster simulations and plasma plume spacecraft interactions.
We develop vacuum chambers combining different diagnostics and thrust balances for RF thruster testing.

Thruster technology

Magnetically enhanced RF plasma
thruster technology

The system is based on Magnetically enhanced RF plasma concept, which is peculiar for its physics comprehension complexity and engineering implementation simplicity.

Immersed electrodes free and neutralizerless

The thruster is characterized by a very simple structure: a dielectric cylindrical ionization chamber (discharge chamber), a radio-frequency (RF) antenna, a gas injection system, a magnetic system for plasma confinement (within the chamber), an outlet diaphragm and a plume screen.
The propellant is first ionized by means of the RF antenna and then expanded within the magnetic nozzle. The system does not present electrodes immersed in plasma and since it ejects a neutral plasma, it doesn’t require a neutralizer, simplifying the fluidic section and the PPU section.
The thruster eject plasmas into space thus doesn’t require neutralization systems. Moreover, it doesn’t implement grids or electrodes exposed to plasmas, thus allowing a very high life time.

Our technology

We have developed an innovative type of antenna system in order to allow better coupling and easier matching in space applications.

Our Technology is patent pending.

WHAT THEY SAY ABOUT REGULUS

"We selected REGULUS as propulsion system for our Unisat-7 because it perfectly fits with our mission requirements and also because its thruster technology is so versatile to fit with our future Unisat family mission needs. This choice is also intensifying our relations with T4i, our partner for Unisat mobility in space."
