Summary
The Rafael Ltd PEPT-230 is a 6 litre Positive Expulsion Propellant Tank with EPDM-based rubber diaphragm qualified for ADN-based green propellant.
The spherically shaped tank is compatible with Hydrazine, IPA, distilled water, GN2 and GHe and has a flight heritage. The pressurant include GN2, GHe and inert gases. The silica-free diaphragm allows for multiple cycles of usage with no limitation to the degree of filling.
The propellant tank is made of made of two thin-walled 6Al-4V titanium alloy hemispheres, cylindrical elongation section (if needed) and a diaphragm integrated to a complete system using peripheral Electron Beam Welding (EBW).
The hot-formed and machined hemispheres are designed to enable the incorporation of integral pressurant and propellant ports.
The space qualified tank has 4 lugs at tank’s equator with clearance holes in 90 degrees distribution for mounting. The storage life of the tank is 7 years, and the flight service life is of 15 years.
