TIE-20 ENGINE

The thrust density of a Hall-Effect Thruster meets the efficiency and lifetime of a Gridded Ion Thruster

In partnership with Turion Space Corporation, Desert Works Propulsion developed the Turion Ion Engine (TIE-20), a Gridded Ion Thruster (GIT) poised to disrupt the electric propulsion market. The TIE–20 Thruster is raising the bar and surpassing expectations—leveraging the advantages of a Gridded Ion Thruster and the higher thrust density of a Hall-Effect Thruster to deliver a superior system: longer lifetime, high specific impulse, and heightened reliability.

GRIDDED ION
THRUSTERS

Gridded Ion Thrusters (GITs) excel in primary propulsion for geocentric and heliocentric space missions, showing consistent performance and lifespan alignment in both ground testing and space operation, setting them apart from other Electric Propulsion (EP) thrusters. However, their full potential remains untapped in Earth-orbital applications, creating a significant market opportunity. The TIE-20 will address this gap.

10x More

Total Impulse

than other EP tech

Benefits

Most versatile and efficient use of propellant among any EP technology
Highest highest total impulse, nearly 10x any other EP technology
Widest power throttling range among EP thrusters, with a single device capable of throttling by up to ~10X
Represents a low-risk technology due to comprehensive understanding of potential uncertainties
As spacecraft power-to-mass ratios increase, GIT technology is the only feasible technology option for specific impulse values exceeding 3,000 seconds
Superior total impulse, efficiency, and specific impulse (Isp) make GITs ideal for missions requiring sustained maneuverability.

Turion Ion Engine-20 System

TRANSFORMING

SPACECRAFT ELECTRIC PROPULSION

Together, Desert Works Propulsion and Turion Space are the exclusive providers of high-power Gridded Ion Thrusters in the US, and our TIE-20 is poised to become the most advanced GIT system ever developed.

It offers an entirely new performance class for the commercial market, all at commercial prices. The TIE-20 system, which includes the thruster, power processing unit, controller, and propellant management system, bridges performance and capability gaps among current EP options.

GROUNDBREAKING

DESIGN

The TIE-20 incorporates all the advanced technological features of NASA's state-of-the-art GITs, including the NEXT—then raises the bar with cutting-edge enhancements.

Experience the unmatched performance and cost-effectiveness of the TIE-20 – there's simply no commercial alternative like it. Contact us today.

The novel all-carbon ion optics assembly and internal components deliver over 10 MN-sec total impulse, surpassing leading EP thrusters by an order of magnitude and outperforming state-of-the-art HETs by 50x.
Optimized for Krypton, the TIE-20 delivers significantly higher total delta-V per dollar than alternatives. Considering future refueling, it’s more cost-effective for long-term maintenance than Xenon and Iodine thrusters, due to lower propellant and launch mass costs per delta-V.
Our second-generation TIE-20 thruster incorporates a breakthrough device which enables thrust-to-power ratios approaching that of Hall-Effect Thrusters, while simultaneously operating at double their specific impulse.
Designed for Earth-orbital use, the TIE-20 offers primary propulsion for point-to-point transfers and auxiliary propulsion for stationkeeping. Its high fuel efficiency and total impulse enable repeated maneuvers for space situational awareness, delivering the highest mission Delta-V among EP technologies cost-effectively.
