Main Engine Cut OffDefects Found in Almost Every Russian Proton Rocket Engine
Matthew Bodner, The Moscow Times:
An investigation into quality control issues in the Russian space industry has discovered that nearly every engine currently stockpiled for use in Proton rockets is defective, the RIA Novosti news agency reported March 30, citing Igor Arbuzov, head of state rocket engine manufacturer Energomash.
71 engines, mostly used to power the second and third stages of the Proton rocket, require complete overhauls to remove defects. Arbuzov did not specify what was wrong with the engines. In January, Interfax reported on an investigation into high-quality metals swapped by a plant manager for cheaper alternatives.
Yikes.
