SteamJet Thruster One: Customise a propulsion system to fit all unused space inside your small satellite.

SteamJet Thruster One is a high-performance (up to 20 mN at <20W), water-based propulsion system engineered for CubeSats and small satellites. While traditional thrusters force you to sacrifice valuable internal volume for rigid, cylindrical tanks, Thruster One utilises additive manufacturing (3D printing) to create bespoke fuel geometries that wrap around your payload, maximising every cubic millimetre of your mission’s potential.

Maximum Volumetric Efficiency: Utilising "Dead Space"

In the space industry, volume is a premium commodity. Thruster One solves the “cylinder problem” by offering conformal fuel tanks designed to fit the unique internal architecture of your satellite.

• Tailored Geometry: We 3D-print tanks to utilise the irregular “dead space” inside standard 3U, 6U, 12U, and 16U frames and even bigger small satellite frames.

• Increased Delta V Budget: By filling corners and gaps that standard tanks leave empty, you can carry more propellant without increasing your satellite’s external dimensions.

• Optimised Centre of Mass: Customise the tank shape to balance your satellite’s mass distribution, simplifying your AOCS requirements.
