This is an amusing exchange. And I think tomcat has been reading 2001
to many times, as in the novel the ship that took the guy to orbit,
was launched by a rail gun type device, and the orbital winged craft
was riding piggy back on the back of a large winged craft that took
the smaller orbital craft to the edge of space. Also NASA in real
life did have such an arragement in ind for getting into space before
the US gov bean counters put a stop to it as it's be to expensive to
develop.

Christopher, I regard it as somewhat amusing myself.

Hate to break it to you, but he's laughing at you, not with you.

Sort of. Just trying to come up with a credible reason to ascertain
why tomcat behaves the way he does.




I have degrees in Liberal Arts and Science, and add to that 'hands on'
aeronautical experience. I don't just accept status quo.

The fact that SSTO is regarded as impossible is the fact that none have
been built, though many designs were made -- and not funded. These
designs for waverider SSTOs date to the 70's. The Space Shuttle is
what came out of that era and in a very strict sense it is not a Single
Stage vehicle. But it comes close -- you just have to drop the
auxiliary fuel tank -- and it does work.

A rocket is still the bet way to get into orbit. HOTOL, was the most
workable concept for SSTO, and the reason rockets are tubular is that
their payload is cylindrical.


I know the foibles of mathematics. They usually involve the premises,
not the functions themselves. So, I look at the premises. And, they
are often pretty bad. Sometimes they are in error, or they turn out to
be circular.

What worked for rockets that rose a couple of hundred feet in the air
back in 1903 does not work well for rockets going to the planets. Even
with the ad hocs of gravity and drag, yet more ad hocs are needed, and
even these additional 'ad hocs' are not enough because vehicle size and
thrust are not properly taken into account in the Tsiolkovsky
Equation's premises. It is, moreover, totally worthless for evaluating
a waverider SSTO. It was not designed for that at all.

It is also interesting that Tsiolkovsky, himself, argued in favor of
'rockets with wings' in his later years.

We cannot allow ourselves to be held back by mathematics that is
inappropriate for the task at hand. While the mathematicians are
working on improvements we need to use commonsense and forge ahead. If
an F-15 can take off like a shot out of a gun with a 1 to 1 thrust to
weight ratio, then a 2 to 1 thrust to weight will really blast you into
the heavens.

When it comes to the practical it is speed achieved and thrust to
weight that do the feat, not old formulas dating back to 1903. In the
year 2006 with engines, materials, and airframes undreamt of in the
70's we have the ability to do SSTO. We just have to build the
waverider vehicle and do it.
