Propellant Tanks - General Description

RAFAEL SPACE Propellant Tanks

Positive Expulsion Propellant Tank - General Description RAFAEL’s Positive Expulsion Propellant Tanks (PEPT) are made of two thin-walled 6Al-4V titanium alloy hemispheres. Positive fuel expulsion is provided by an EPDM-based rubber diaphragm retained in the tanks. Pressurant and propellant ports are weldable, 1/4” titanium tubes.

The Propellant Tanks are made of the following parts: • Lower hemisphere • Upper hemisphere • Cylindrical elongation sections - if needed • EPDM-based, silica-free rubber diaphragm

Integration to a complete tank is accomplished through peripheral Electron Beam Welding (EBW). Hemispheres are hot-formed and machined to final dimensions (exclude PEPT-200). The design of the hemispheres enables the incorporation of integral pressurant and propellant ports.

The diaphragm has a life expectancy of 15 years when used with hydrazine propellant and has been qualified for various missions and satellite busses, such as Globalstar2, Myriade, Galileo, Exomars, Neosat and others. The diaphragm has further been qualified for use with ADN-based environmental-friendly (“green”) propellant.
