Re: The Cold Equations

Jorge R. Frank,
Usenet contributor "tomcat" isn't nearly as perfect as the likes of
yourself. However, even though I do not agree with the basis of many of
his suggestions, he dose own and pretty much operate by way of whatever
his pagan lord and master's (aka NASA) bible has to offer. Whereas his
spaceplane and notions of using the likes of titanium alloys along with
the 4.84 GPa basalt and perhaps even a bit of spendy CNT composites
isn't without just cause, taken from perfectly honest research and
thoughts that are obviously the sorts of free thoughts outlawed within
NASA, whereas knowing too much about anything and especially about many
things is potentially lethal.

1) there's no such thing as one and only one formulated alloy as being
titanium, as there are dozens of such titanium alloys, each tailored to
suit a given application.

2) It's an alloy of titanium and not one of aluminum that's utilized
throughout most all hot sections of a jet/turbine engine that are
associated with the sorts of thermal plasma, as well as most likely of
what's involved within all critical thermal plasma related workings of
any SSME.

3) there are a few other thermally tough allows than having the
"titanium" tag, that are even somewhat better yet, none of which
involves your beloved "aluminum" unless you're talking about a
sacrificial application.

4) thermal heat transferring is a two-way ticket to ride. Whereas it's
a wee but better off having an isolated hot-spot or two that can be
easily shield form affected the internal workings and crew, that a
whole lot better than having total structural failures running amuck.

5) taking "tomcat's" information out of context and using it as
leverage in order to improve upon your point of argument is exactly the
sort of proof-positive that you're every bit as brown-nosed and
intellectually incest cloned as they come.

6) It might help if you actually applied some careful engineering
rather than pulling ideas out of your mainstream status quo ass, such
as using hard-science and the regular laws of physics for a change,
although that'll mean picking out your extremely brown-nose, as clean
enough to breath again.

7) Depending upon the alloy and thickness of titanium, I'd have to
place the reentry thermal tolerance at 130 seconds better off than
aluminum, therefore way more than the 13 seconds as suggested by
NASA/CAIB, thus affording enough time to have said the Lord's Prayer.
Somewhat thicker applications of composite layers of titanium and
basalt composites as for providing insulative inter-layer binders
should become capable of offering 1300 seconds to the untiled
burn-through criteria of achieving total structural failure.

8) Criminal negligence of homicide needs to be placed upon the backs of
those responsible for their piss-poor inspections and deficient
servicing of the protective thermal tiles, as well as per the R&D teams
as having their ***-protecting 'so what's the difference' policy of
essentially not doing their jobs.

9) There's no excuse for the shuttle not having a composite covered
hull of mostly titanium that's ceramic coated and/or as having scale
like ceramic tiles that are mechanically associated with the primary
hull, then also having an internal backing of a thermal barrier which
could also have been of a light weight but otherwise structural basalt
composite. Essentially a matrix of composite barrer layers that if
damaged would sufficiently survive reentry.

10) Regardless of the quality and thermal capability of the outer hull,
as for so much as running into an empty beer-can at such velocity is
not an acceptable option by which a single all-or-nothing design can
survive.

The sorts of advanced spaceplanes being suggested by "Robert Mook" as
having no mass limitations and otherwise especially that of what
"tomcat" has proposed as inert becoming darn near buoyant will require
a fully serviceable primary, secondary and possibly even a third viable
barrier on behalf of at least protecting the crew, that which combined
will essentially take a horrific physical and thermal licking and keep
on ticking. Whereas your ***-saving insistence that only aluminum
alloys need be involved as the primary hull, as covered by essentially
ceramic post-it notes with lose gap fillers that together remain as
non-structural items of each tile thus individually ultra critical as
being all or nothing simply is not acceptable.

Obviously a singular paper thin layer of whatever titanium hull, or of
most any alternative ultra-alloy, isn't going to be survivable as naked
of tiles unless there are a few survivable layers backing that up. A
reduction in reentry mass/m3 is certainly another worthy look-see, as
proposed by the "tomcat" ultralite spaceplane that would have become
nearly if not potentially buoyant at 50,000'. In other words, depending
upon whatever returning payload, the ultralite spaceplane as
essentially being a rigid-airship would have to allow atmosphere into
the massive volumes of essentially empty tanks enclosing the near
vacuum of space in order to land. Applying this very same concept to
Venus and you'll get my ultralite spaceplane drift, or perhaps you're
simply too dumbfounded for even considering that much.

Of course, I personaly feel that manned space flights as a whole are
unacceptable investments no matters what, especially since we still
haven't a viable fly-by-rocket lander, nor a space-station-depot that's
LL1/ME-L1 situated and much less having been tethered to the moon as
our one and only viable home away from home. Space flights via robotics
isn't 0.1% the investment of anything manned, nor are robotics going to
take 10% the time in order to have achieved the given task and goals
that are needed for the near future. The only reason we'd need to
personally leave Earth is because of the likes of certain LLPOF fools
what would justify our past, present and future as based upon
perpetrating whatever it takes in order to get us unto WW-III.

There is not actually any shortage of easily accessible clean energy
within the environment of Earth, whereas the green/renewable
alternatives of obtaining a footprint worthy of 25 kw/m2 isn't
insurmountable, that is other than the nearly insurmountable mainstream
arrogance, greed and intellectual plus biological bigotry that's still
running us amuck, which has cased wars in the past, of the present and
will most likely involve even nastier wars as based upon the lack of
and spendy remainders of fossil/geological and of nuclear fuels in the
near future, all of which are rather nasty and spendy to obtain in the
first place, extra spendy in order to safely process, as per storage
thereof and/or lifetime berrials thereof, physical transportings and to
otherwise safely distribute/transmit such energy to the end-users.
