| Nasaspaceflight.com’s Chris Bergin finally wrote the article on Ares I’s thrust oscillation mitigation options. There are three main ones: new pulsed brake rockets, a damper between stages and a tuned small mass damper in the SRB. All three could be applied. They also increase mass and thus reduce performance.
Ares I’s thrust oscillation coupled with the whole rocket’s already looming possible underperformance and the Orion spacecraft mass growth drives towards a possible no win situation. It’s a bit hard to know about the margins.
There is only one earlierdocument making a clear picture of the masses, performances, margins and
reserves out there:
Brian Muirhead’s presentation from 31 Jan 2008. (Thanks to Renclod on Nasaspaceflight’s forum for finding it.)
So it seems there could [...] ... |
