HOW OUR TECHNOLOGY WORKS
Our thrusters take a different approach to generating ions, compared to traditional ion engines.
Our thrust-producing ions are supplied from our ionic liquid propellant — a safe, non-toxic liquid salt. This novel source of ions allows us to avoid the use of large ionization chambers, pressurized tanks, bulky valves, and external cathodes.
Our technology is built around a thruster “chip” architecture. Each chip houses hundreds of microscopic emitters that produce beams of ions generated from our novel propellant source: ionic liquid.
Similar to traditional ion engines, our systems produce thrust by using electric fields to accelerate ions. Ions leave the thruster chips through small holes in the extractor grids over each chip, and propel the spacecraft in the opposite direction.
BENEFITS OF ION ELECTROSPRAY PROPULSION
Smaller, simpler design. No need for an ionization chamber, valves, pipes, external neutralizing cathode, or active pumping or pressurization in Accion's thrusters.
Optimized for high thrust-to-power ratio. No external cathode or propellant heaters that draw additional power.
Conversion efficiency. Up to 60 percent higher than plasma thrusters.
Reduced lifecycle cost. Due to safety of propellants.
Rideshare safe. The passive nature of our non-toxic, non-explosive ionic liquid propellant allows our thrusters to comply with all rideshare and launch regulations.
Wide thermal stability. The thermal stability of ionic liquid ranges from roughly –100 to 400°C.
Batch manufacturing techniques used to fabricate our thrusters allow for increased reliability and reduced cost.
