The X-3 isn't only going to fail to breech the flame barrier, but also
the sound barrier.
Thanks for this. I added it to my X-3 collection.
Ever see this?: http://www.periscopefilm.com/dox3stpiflop.html
There's videos of it over here:

I always wanted to see a artist's concept of what it would have looked
like with the lenticular ramjets inside the wings.

There was a quite similar article in Science Digest around the same
time, titled, "Can we crack the Heat Barrier?"

Didn't know about this. Thanks.
It reminds me to find the site that has the Airacuda manual. I thinkl
my ex-wife threw it away.
Thanks. I found these on the NTRS site. There's two different
versions of EM-0030-01: one is 1120k and the other is 4610k.

This is a new idea. What are lenticular ramjets? I have photos of
the X-3 with ramjet tubes on the wingtips, but nothing lenticular.

With that in mind, what is the "flame/heat barrier"?
Not expecting an answer, but thanks anyway,
Aerodynamic heating that occurs at multi-Mach velocities.
This was a big bugaboo in the 1950's, when aircraft were pretty much all
built out of aluminum and magnesium alloys, but the article does talk
about titanium being able to deal with the heat, and the X-15 showed
that nickel alloys could also be very useful in this regard in the years
after the article was written.

The lenticular ramjet was to be mounted inside of the wing with the
whole leading edge incorporating an inlet along its length, combustion
occurring inside the wing structure, and the trailing edge forming the
exhaust.
Never heard of it. I think. Wasn't there an idea about an externally-
ignited ramjet?
Thanks. In my wanderings through old NASA papers, I've seen that
shape -- the big wing and cruciform tail -- in some drawings, but I
never paid any attention to any of that.
Quote: Oddly, if you look at the wing design on the Pan-Am Space Clipper from
"2001", it looks like it may have lenticular ramjets incorporated in it
also, feeding from multiple inlets on its leading edge that exhausted
over the rear top surface of the wing.
I noticed that "step" in the Space Clipper wing when I built the
model. I never thought it might be anything more than a quirk of the
Aurora kit, or at most maybe just a simple wing.
