PDF Review: X-20 Dyna Soar Progress Report

Seems I’ve been a wee bit lax on the PDF Reviews I will attempt to rectify that in the future.

Here is a Air Force conference paper from May, 1964, describing the X-20 Dyna Soar program and vehicle. At this point the program had been cancelled for some months; the configuration shown in the paper was essentially the final design. It’s a decent overall view of the Dyna Soar.

Here’s the link to the abstract:

Hypersonic testbed

Dating from about 1963-63, this is a depiction of a high-altitude research aircraft equipped with “composite air-augmented turbo-jets” for launch and rockets for “near-space operations.” The general configuration was used many times over the decade, typically for scramjet powered aircraft. This was painted by Pat Shealy, chief of the Presentations Division, Air For Office of Scientific Research at Wright-Patterson Air Force Base.

So very, very close on the next two US Aerospace Projects issues. I’m only lacking cover “art”and have to deal with a bit of “dead air” in the middle of US Transport Projects #7. Usually I can shuffle things around well enough to not have this sort of thing, but this time it just hasn’t worked out. I suppose it doesn’t really matter all that much, but it does look kinda lazy like that.

It’s been about a year since I released the last USxP issue. That last issue was the first time where I used vector diagrams embedded within the issue, rather than raster images; getting the diagrams from AutoCAD into Word was a bit of a chore back then. And in the intervening months… I forgot how I did it. So I had to figure it out again, and the process is different. I have to walk the AutoCAD diagram through Rhino 3D and save as a WMF and blah, blah, blah; end result is it works just fine. I’ve done some further refinement… the main outlines are set at 0.25 mm width and the ends of the lines have been reset to rounded and mitered, so sharp corners now look more like sharp corners.

Hoping to have these two out in a day or two. The other three will be rather longer.

I’m essentially done with the drafting portion of the exercise. Now to finish the writing. I had planned on releasing ll five at once, but due to external factors I’ll almost certainly have to split this up. So… which ones do people want more? The publications forthcoming are Fighters, Bombers, Transports, Launchers and Recon & Research. Comment below…

Mar 102017

Coming soonish: the return of USXP publications. Five are under current development and are mostly done. There is a new title in the bunch… USRP. Strictly speaking it should probably be USR&RP… United States Research and Recon Projects. Perhaps Recon and Research aren’t necessarily the most obvious categories to link together into a single title, but apart from the vitally important alliteration, there is this important fact: compared to, say, Bombers, there aren’t that many Recon and Research projects out there.

If there are specific proposals, or general categories you’d like to see in future publications, feel free to comment below.

Some aerospace art & photos for Patrons

Mar 042017

I have posted in the 2017-03 APR Extras Dropbox folder for APR Patrons a small pile of aerospace history images yoinked out of a few reports. Included is a 1944 NACA reconstruction of the German V-1 buzz bomb (generally correct, but off in detail), three photos of a wind tunnel model of the Bell X-1 modified to have variable sweep wings, three pieces of NASA art depicting some then-future applications of space propulsion systems including a one-man lunar flyer, an early concept for what became Skylab, and a more advanced modular space station. The full-rez verions are available to all APR Patreon patrons at the $4 level and above. If interested, please consider signing up. There are a whole bunch of other goodies available in past months folders, more stuff coming.

Much more aerospace stuff is available via the APR Patreon. If this sort of thing interests you, please consider signing up… not only will you help fund the search for obscure aerospace history, you’ll gain access to a lot of interesting stuff, not available elsewhere.

NASA hypersonic model

A photo of a NASA wind tunnel model of a hypersonic aircraft configuration. The circa 1960 NASA brochure (promoting the organization to college students) that included this provided no further information, but I’m reasonably sure I’ve seen the wind tunnel test report on this, calling it a reusable booster or reusable launch vehicle. If that’s the case, the upper stages and payload were *probably* going to be carried on the things back.

Curtis-Wright X-100 VTOL film

A silent NASA film documenting flight testing of the little-remembered X-100 in 1960. The X-100 was a slick-looking tilt-prop design, a predecessor to the X-19. In this video is certainly looks rather wobbly in the air as the pilot attempts to hover. The craft could certainly have benefited from modern computerized controls.

APR Patreon November Rewards

Nov 272015

Just under the wire, rewards for November have been made available to APR patrons. Three documents and one large-format diagram, and one all-new CAD diagram, have been posted:

NASA diagram (on two sheets) of a NERVA nuclear rocket engine display model, presenting the configuration with detail and clarity
An article on a orbiting nuclear power station
A full-color brochure (via photographs) on the Convair Model 36, their entry for what became the B-36
A North American Aviation presentation on delta wings for the X-15, presenting a few different configurations
An all-new layout CAD diagram of the Bernal Sphere space colony concept

If you’d like to help out and gain access to these and past and future rewards, please check out the APR Patreon.
