About
This monopropellant tank features a stiff-plastic separation device (diaphragm) and is designed for the storage and feed of liquid propellants, specifically UDMH and NTO, to liquid propellant thrusters. It was released in 2011 and has flight qualification with a letter “O” for flight use. The product is adaptable to customer requirements. Key specifications include an operating pressure not exceeding 1.67 MPa, a mass of 5.2 kg, and a propellant compartment volume of 30.8 dm³. It ensures an unused propellant residue after expulsions of not more than 0.65 dm³. The tank maintains high cleanness with an inner compartment cleanness meeting Russia State Standard GOST 17216, Class 5. It has a guaranteed service life of 15 years and strict allowable helium leak rates during leakage tests and throughout its service life.
