Composite Type-V pressure vessels
All-composite, linerless, unibody pressure vessels built with Hexcel carbon fiber and Sapphire 77 cryogenic resin. A vessel can serve as the primary structure of a launch vehicle or spacecraft.
Composite spacecraft propellant tanks
Scorpius Type-V propellant tanks work with chemical and electric propulsion. They have fewer failure modes than traditional approaches.
Mounting built into the tank
Longitudinal and circumferential stringers carry integral shelves and customizable holding mechanisms. You attach spacecraft equipment to the tank itself.
Less support hardware
The stringers replace separate struts, straps, braces, clamps and brackets. This makes it easy to install payloads and bus subsystems.
Stable across temperature
The tank has a very low coefficient of thermal expansion from cryogenic temperatures to 175 F.
Flight record
- Two Scorpius composite propellant tanks, methane and liquid oxygen, flew on the Intuitive Machines IM-2 Athena lander.
- Scorpius Type-V tanks supported the Intuitive Machines IM-1 lunar mission.
Questions
Have your tanks flown?
Yes. Scorpius tanks flew on the Intuitive Machines IM-1 and IM-2 lunar landers.
