Angara, and the Future of Russpace


Recommended Posts

It looks like a reasonably good design to me; the RD-191 appears to be a pretty solid engine, and the basic architecture looks sound. Ultimately, I think its future is going to be more dependent on the state of the Russian economy and future Russian actions in the political/military sphere rather than any major technical issues. Another (somewhat related factor) is going to be how well the private spaceflight sector develops; if Elon Musk manages to launch Falcon 9s as cheaply and as regularly as he claims,  it will probably cut into the Angara's non-government customer base. Although it likely won't eliminate it entirely, given that the A5 has quite a bit more payload to LEO than the non-Heavy version of Falcon 9.


Overall, though, the design looks good, and congrats to Roscosmos and friends for putting together a whole new launch vehicle design, especially after the hilarity that was Russia in the 90s and early 2000s.

      Let's see if it can live up to its namesake, Vulkan;

      Edit: added more stuff about ULA rocket;

      Looks like they're planning on having reusability, although apparently not of the whole first stage like on Falcon 9.  Also, midair recovery, which is an interesting choice.

      Seriously, look at this shit.

      Doing a backflip at Mach 5 with the external tank still attached, NBD.
      Rumor has it that the scenario was possible in the sim with an intact shuttle, but in just about any case where you're doing an RTLS the shuttle most likely isn't intact (if it was you could just a transatlantic abort or something). There's also rumors that STS-1 was planned to be a test of the RTLS scenario, before John Young helpfully pointed out that was a retarded idea.

      This is a discussion thread for the greatest horror villain of our time, the Space Transportation System, more commonly known as the Space Shuttle.

      First, I want to say something positive about the Space Shuttle, and that's that it, and its offspring SLS, has one of the most ingenious launch arrangements out there. Sure, solids may not be the absolute best thing ever for manned spaceflight, but the "two high t/w boosters, one central core with mega-awesome high ISP high thrust engines" arrangement is seriously a great idea. The fact that they pulled it off is even more awesome.
