Re: How Rockets Differ From Jets

tomcat,
I can't speak for whatever's your spaceplane obsession of devising upon
a new and improved yet conventional SSME powered craft for somewhat
conventional airport usage that'll make commercial orbits and
deployments affordably common place (key word "affordably" meaning
something a whole lot less spendy than $100,000/kg), as without a few
of those SMEs/SRBs there's no viable way of getting that much mass to
even a spendy and complex refueling altitude. However, my obsession or
mindset with utilizing basalt as a nearly do-everything composite is
similar to the nearly do-everything aspects of utilizing H2O2, whereas
H2O2 isn't the most rocket exhaust velocity for the buck. However
H2O2/Aluminum is certainly offering us one heck of a battery energy/kg,
and H2O2/C12H26 is offering a terrific density of extremely powerful
rocket elements, that which provides a great deal of thrust potential
that isn't requiring nearly the complexities and extra volumes of space
as per slush LH2/LO2, nor is the process of creating and subsequently
storing the H2O2 and C12H26 nearly as energy and infrastructure
consuming as per artificially creating LH2/LO2.

In other words, those German rocket scientist and aerodynamic engineers
still seem to know ten fold more about the benefits of using H2O2 than
we'll ever realize. We're even too dumb and dumber to realize what a
sadistic pervert we have as our commander in chief warlord(GW Bush),
that's about to push the ultimate 'do-not-push' button of WW-III simply
because we're too dumbfounded to figure out how to safely extract clean
renewable energy from a solar-stirling/wind and PV tower footprint
that's been good for as much as 25 kw/m2. Instead we'd rather lie our
butts off while causing so much collateral damage and carnage of the
innocent, thus making enemies of Muslims in the process. Gee whiz
folks, what could possibly go wrong with that approach?

If we're still alive to benefit from what's been doable, such as
creating basalt composites upon or preferably well above the surface of
the moon (such as safely within the massive CM/ISS sphere that's
offering a tethered abode of 1e9 m3) is an absolute win-win for that
sort of technology, whereas the process of creating basalt fibers and
of those extremely nifty basalt balloons (especially if we wanted those
little hollow spheres to have a vacuum within) needs a clean resource
of energy by which to melt and process the raw basalt, of which 1.4
kw/m2 is certainly more than sufficient from the standpoint of a solar
farm as established for a lunar surface or LSE-CM/ISS basalt processing
plant that would obviously work best if this basalt and solar farm were
situated in such a near vacuum to start with.

Of course, we could just through away all of the other viable secondary
process elements, such as lunar Titanium, Aluminum, Radium, U238 and
He3. Here's that same old NASA infomercial video that was created when
Oil was hardly $10/barrel, big aircraft weren't smashing into tall
buildings, stingers weren't taking out 747s, ABLs weren't taking
practice shots at incoming shuttles and we weren't at war with Muslims
that are sitting on most of the affordably accessible oil:

NASA He3 infomercial: http://www.nuenergy.org/video/helium3.rm
Of course using He3/fusion as a spaceplane energy on behalf of
whatever-->ion thrust might suggest a good method of affordably using
just about any element as a viable source of ions.

Wherever the composite application temperature is less than 500°F
(intermittently 600°F) is where the likes of JB-WELD might be
considered as a sufficient binder (key words "likes of JB-WELD"
suggesting upon fairly common epoxy form of binder). However, I'm
certain that others and yourself can find a 10+fold if not a 100 fold
spendier/kg worth of an exotic epoxy that'll do a bit better, as well
as being nearly impossible to apply under anything but the most ideal
environment, meaning that your replacement super-whatever-epoxy may not
be nearly as field reparable as JB-WELD, although it will not likely be
your bank account nor your sorry *** that's on the line, so what's the
difference?

I'm willing to explore the spaceplane notions even though I'm not
entirely convinced that such a very large scale spaceplane (especially
of an airfoil body and thus without wings and as based upon
conventional SSMEs) as having built-in deployable aerobreaking is even
going to get itself as hot and nasty upon exit/reentry as per what's
being suggested, at least not for very long at any one application.
Using a spray-on ceramic and/or those scale like ceramic tiles, plus if
need be introducing LRn as an extreme refrigerant or merely as a freon
like thermal conductor, and/or perhaps for creating a high density
boundary layer between the reentry plasma gas and that of the outer
hull seems somewhat doable as long as the volumes of released LRn are
not too excessive. The option of implementing outer skin cooling via a
circulated matrix of fully enclosed LRn-->Rn that'll then become fully
utilized as ion retro-thrusting form of Rn-->ions is simply my way of
suggesting upon a more advanced method (though obviously unproven) of
essentially taking advantage of the available thermal heat-exchanging
dynamics LRn without actually wasting a kg of Rn that needs to go into
making those ions.

BTW; as long as you're the one excluding nuclear thrust derived energy,
my previous notions of a highly modified A380 super-air-tanker that's
H2O2/C12H26 assisted is simply stating that such a modification
wouldn't require 50% the engine and fuel mass as would conventional
engines and fuel, allowing the A380SAT to cruise much higher and faster
with a greater payload of LH2/LO2 for your thirsty spaceplane that'll
need every last tonne of fuel it can get, and then some.

BTW No.2; I'm still getting way more than my fair share of my PC being
hit with a tonne of GOOGLE/NOVA accommodated spermware/malware, thus
the MI6/NSA~CIA spooks and their extremely brown-nosed freelance
supporters are still hard at it, applying as much damage control
without spilling any more of those perpetrated cold-war beans than they
have to. You don't suppose that I'm on to anything?

Kurt Vonnegut would have to agree; WAR is WAR, thus "in war there are
no rules" - In fact, war has been the very reason of having to deal
with the likes of others that haven't been playing by whatever rules,
such as GW Bush.
