Titanium Bipropellant Tanks for Satellites and Spacecraft

Portfolio of space qualified titanium bipropellant tanks for satellite and spacecraft propulsion systems.


Our selection of titanium bipropellant tanks range from 198 litres to 2100 litres. A tank capacity may be precisely matched to system requirements by varying the tank cylindrical section length between the domes.

 

Most of the propellant tanks manage propellant via internal surface tension devices. The range also includes an aluminium alloy diaphragm tank, a tank for spin stabilised spacecraft and a tank with liquid C of G control. Some bipropellant tanks are also qualified for use with hydrazine propellant.

 

A brief overview is available for surface tension tanks, together with an insight into our propellant tank manufacturing facilities.
