Technical update

[edit]

I have a few details regarding the A2100 spacecraft from my years with After Columbia Project (no affiliation with Lockheed Martin) that I scrounged up with some publicly available documentation. Why commercial satellite manufacturers are so guarded about such details remains a mystery to me. Featherwinglove (talk) 22:37, 26 May 2014 (UTC)[reply]

  • It is, unfortunately, nothing more than informed speculation, but I do believe that the A2100 and MGS share the same main motor. There is a crap-tonne of information available on the MGS, whose main motor produces 660N of thrust at 315-317sec of Isp with an OFR of 0.85 (the A2100's max load OFR is 0.47, so in the AX configuration, it has a huge surplus of monopropellant hydrazine for orbital operations.) The Sirius 4 spacecraft, as simulated in the Orbiter simulator, is quite easy to fly at the 660N thrust level. I could not find an ion propellant tank for this craft when I searched SSI's catalog (although they do have quite a few for Boeing spacecraft.) Featherwinglove (talk) 00:03, 27 May 2014 (UTC)[reply]
