Hi Pete,
Good to talk with you again! I noticed you're making good progress,
looking forward to seeing your engine fired up!
On your response to my earlier post -- yes, I concur with that
assessment... I just wanted to note that some of us here (you and I
for instance, and I'm sure several others) have taken this up as the
"kung fu challenge" – who's got the best kung fu... We have the
capability to do it ourselves. It's not that we couldn't put together
a huge team or farm everything out, it's just that we have chosen not
to because it doesn't fit within the nature of our own reasonings for
taking the challenge in the first place.
On the other hand, even if we work "by ourselves" we can never work
"alone." We can't separate the immense contributions of others
throughout the ages. We use tools, computers, the internet, research
studies, commodity components, etc., and the list goes on and on. So,
each of us has to be comfortable as to what fulfills our own personal
goals, and where we want to take that. And, there are certain guiding
principles present within the gestalt.
Personally, I'm interested in the aspects of the system that haven't
been done (or integrated as such) -- the required innovations to make
this happen. And, this effort is chock full of them; many people
don't even think it's possible. But (for example) I'll be using
commercial electronics components; I could certainly fabricate my own,
but to make a competitive micro-controller from ground zero is more
difficult (in certain respects) than the N-Prize itself. It's not my
goal to do the same thing that's been done, and those components are
already up to the task.
So, noting your example within my context... It wouldn't matter that
much if I fabricated an engine or farmed it out, so long as system
wise, it's my innovations and designs; such fabrication is a well
established trade. However, it would be quicker and easier if I built
the prototypes because there are certain aspects to engine
construction that come from experience in building them. On the other
hand, if I had a special material or engine construction technique,
then I might want to fabricate myself.
In your case you've opted for differential throttling; you feel it's
overall advantageous (at least for your system) to build and manifold
eight engines rather than use gimbals or other methods; that's a
design choice and perhaps it's better for your overall design. As
such, you'll build the engine get it working properly, maybe build few
more and refine them if needed, and then once it meets your criteria,
send the design to a machinist for high-tolerance replication. That
makes sense to me and it's probably the same thing I would do.
On your last point, I would say that any individual or group (whether
small or large) who completes (or even makes a credible attempt) at
this challenge is quite worthy since the challenge is (by design) open
to any such groups. So, we may be competing against larger teams, but
that's fully within the context of which we took the challenge (and
for me, such adds to the allure of it -- I like the idea of having
huge teams trying to compete against one or a few people, it just
makes it that much more interesting).
So don't get me wrong, I (and I don't think many others for that
matter) would say that someone (or some group) 'failed' because they
tapped into existing commodity, knowledge, or infrastructure. On the
contrary, that's exactly what makes all of this realistically
possible! But, all the novel things that make this actually work, the
intricacies in the designs, the mechanical, the electrical, and
software engineering, the physics, certain levels of fabrication, all
of those things and much more... Well, that's the essence of the
challenge itself. For me personally, to split those unique aspects
among tons of specialists is not so much fun, and certainly not
correlative with my reasons for taking this challenge.
Anyway, this is getting really long winded... But, I do want to
comment on some of your (very interesting) work; possibly a bit later
today...
