Airships to orbit

Tom Brosz — 5/27/2004 3:07:34 AM (archived)

I vaguely remember someone else posting a reference to this concept, but it's cool enough for an encore.

If this works, it could be a breakthrough. I could see a lot of moneymaking applications other than transport to orbit for the first two vehicles in the architecture.

    - A scramjet won't get you into orbit (they flame out at Mach 10). - David F Mayer - 6/1/2004 1:03:18 AM

        Use a detonation wave analogy to understand this - Gary - 6/2/2004 3:27:55 AM

    - Look at the VOLUME of a balloon of ANY type required to lift a reasonable spacecraft to 30,000 meters. - David F Mayer - 5/30/2004 1:35:00 PM
  - I was only referring to using a balloon to lift a rocket here. (n/t) - DFM - 5/30/2004 5:19:50 AM

    - Use VASIMR - phil - 5/27/2004 12:42:19 PM
      - For a large balloon, at any altitude, the air resistance even at low speed is comparable to its weight. I STILL say the idea is bullshit. (n/t) - David F Mayer - 5/30/2004 1:37:21 PM
