About
This bipropellant tank features stiff-plastic separation devices (diaphragms) and is specifically purposed for the KDU 11D414HC propulsion system, which is used in communication satellites. The product has achieved ‘Letter “O”, flight use’ flight qualification, indicating its readiness and proven capability for space missions. It is designed for the storage and feed of propellants to liquid propellant thrusters. The manufacturer also states the possibility to adapt the product to customer requirements. Key specifications include its compatibility with UDMH/NTO propellants, an operating pressure not exceeding 2.94 MPa, a mass of 15.5 kg, and a total propellant compartment volume of 40 dm³. It ensures a low unused propellant residue after expulsions, not over 2.2 dm³, and maintains stringent leakage standards throughout its guaranteed service life of 15 years.
