Quote Russian scientists find defect in new heavy lift space rocket engine (Reuters) - Scientists have discovered a defect in the engines of Russia's new flagship heavy lift space rocket that could destroy it in flight, an apparent setback to a project President Vladimir Putin has said is vital for national security. The Angara A5, which was test-launched in 2014, is being developed to replace the Proton M as Russia's heavy lift rocket, capable of carrying payloads bigger than 20 tonnes into orbit. A launch pad for the new rocket is due to open in 2021. In July, Putin said the Angara A5 had "huge significance" for the country's defense and called on space agency Roscosmos to work more actively on it and to meet all its deadlines. > The paper, reported by RIA news agency on Friday and published online, said the engines of the Angara A5 could produce low frequency oscillations that could ultimately destroy the rocket. A special valve had been fitted to mitigate the issue, but in some cases the oscillations continued, it said. Energomash did not immediately reply to a request for comment. > Link to comment Share on other sites More sharing options...
DocM Posted January 18, 2019 Author Share Posted January 18, 2019 RIA reports a reasonance occurs when it throttles below 38%, and mitigations sometimes do not work. https://ria.ru/20190118/1549528681.html Unobscured Vision 1 Share Link to comment Share on other sites More sharing options...
Unobscured Vision Posted January 18, 2019 Share Posted January 18, 2019 Those low-throttle oscillation/harmonic conditions can be a pain to sort out. Fix it at one level and it crops up at another. We know all too well what those oscillation problems can spell for budding Programs ... just ask the Ares/Constellation folks. Hopefully they'll figure this out, or simply workaround by not going below 39% thrust unless they're in MECO/BECO. Link to comment Share on other sites More sharing options...

Peresvet Posted April 12, 2020 Share Posted April 12, 2020 Happy Cosmonautics Day, friends! There're no public celebrations this year in Russia due to COVID. However, next year's 60th anniversary will be huge! And just the other day I learned that if Earth was just 10-15% larger, our current technology wouldn't even allow us to overcome the planet's gravitational pull and launch into space. Imagine that! Come to think of it, we're also extremely lucky to have the Moon which will be crucial for exploring the Solar system in the future.
