Will Russia’s most powerful rocket engine be reborn?
The competition heats up? The original builders of the hydrogen-oxygen engine that launched the Soviet Union’s most powerful rocket, Energia, are pushing to restart production of that engine.
By 2013, the KBKhA design bureau, which developed the original RD-0120 engine, declared its restoration as one of several high-priority projects. According to a schedule developed by KBKhA in coordination with its manufacturing arm — the Voronezh Mechanical Plant — the RD-0120 could be brought back to production in six years, given adequate funding.
The final decision on the restoration of the RD-0120 would depend on the approved architecture of the super-heavy rocket, whose development was included into the latest draft of the Federal Space Program from 2016 to 2025. Plans to restore RD-0120 had its critics, who believed that a new investment into the hydrogen propulsion technology would be too costly and risky for the Russian rocket industry. A recent analysis of prospective super-heavy rocket designs by RKTs Progress, the developer of the Soyuz rocket, favored methane and solid propellants over the liquid hydrogen. At the same time, an alternative proposal from RKK Energia, the Russia’s chief manned space flight contractor, featured the RD-0120 engine on the third stage of the super-heavy Energia-KV rocket, industry sources said.
I’m not sure if it will be economically wise for Russia to focus their energies on this engine, or on a super-heavy rocket. Like NASA’s SLS, such projects look great for politicians and provide a lot of pork, but they generally are too expensive to accomplish very much.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

“gaseous hydrogen for pressurization of the oxydizer tank….” Really? What is the Russian word for explosion?
In the absence of any initiating heat source, this should actually be relatively safe. Not too much heat in a cryogenic propellant tank. More generally, the Russians don’t really have a lot of choice here. There are only two gases that stay gases at liquid oxygen temperatures, helium and hydrogen. The Russians have lately started to extract helium from some of their natural gas wells, but their aerospace industry has no long history of working with the stuff like ours does because,until recently, the U.S. had a near monopoly on helium production. Gasifying a bit of the liquid hydrogen fuel as a pressurant using some kind of heat exchanger is a straightforward exercise when formidable heat sources, such as large rocket engines, are handy.
About the advisability of Russia building a monster rocket, that depends mainly on whether it is reusable. If not, it’s a waste of resources, but, hey, confusion to the enemy, right? The Chinese also have a giant rocket in the works called the Long March 9. Perhaps its just two more manifestations of the long-time commie love of industrial giantism. Too bad so many of our own citizens seem similarly hypnotized by the idea of big, hyper-expensive, throw-away rockets.
