This looks a bit like 1960 era Soviet engineering (remember the N-1), and I would suspect some trouble with synchronizing all these engines.<br /><br />If I were being asked to do this, I would give serious consideration to the Sea Dragon design, which seems far cheaper and more robust, and still capable of lofting 550 toms of payload to orbit.Thucydideshttps://www.blogger.com/profile/09828932214842106266noreply@blogger.comtag:blogger.com,1999:blog-192883022973901942.post-75950394381194878272016-10-05T06:31:07.223-07:002016-10-05T06:31:07.223-07:00It's pointless to aerobrake into Jupiter as th...It's pointless to aerobrake into Jupiter as the gravity well is too deep.
