Q20203120




The RD-0210 (Russian: Ракетный Двигатель-0210, romanized: Raketnyy Dvigatel-0210, lit. 'Rocket Engine 0210', GRAU index: 8D411K) is also known as the RD-465. It and its twin, the RD-0211, are rocket engines using unsymmetrical dimethylhydrazine (UDMH) as fuel and dinitrogen tetroxide (N2O4) as oxidizer in an oxidizer rich staged combustion cycle. They have a single nozzle, possess thrust vectoring and are the latest evolution in the RD-0203/4 lineage. They are the engines used on the Proton second stage. The RD-0213 is a fixed nozzle variation that is used on the RD-0212 module of the Proton third stage.
