I listened to the annoucement of the Vulcan NGLS booster from ULA.
The graphics released and show at SpaceFlightNow.com show a line. "350% more lift" but I could not figure out where that is coming from.
First issue is, 350% improvement is 3.5 times more than "what"?
The CEO said they get about 30% more boost from core engine changes plus 20% from 6th booster. Where is the rest of the increase from?
The 30% engine boost would likely be 2 X BE4's vs a RD-180. 1.1 Millions lbs thrust vs 800,000 lbs thrust.
The 20% increase from 6th booster makes sense. If you had 5 and add a 6th that is about a 20% increase.
But the overall 350% compared to what? And from what improvements?
I will assume he is suggesting with the new upper stage, perhaps to BLEO or GTO/GSO orbits. But they never explain what this all really means.
