A piece of artwork (almost certainly a negative, based on the shading and the national insignia) depicting the Kaman K-16 deflected slipstream tiltwing VTOL flying boat project. The K-16 was actually built in 1959, but never flew and was cancelled in 1962.

The airframe somehow managed to survive and is on display at the New England Air Museum in Windsor Locks, Connecticut. I visited there a couple times years ago and took a number of photos, posted HERE (2001 visit) and HERE (2007 visit). The full rez scan of the artwork has been made available at 300 DPI to all $4/month patrons/subscribers in the 2021-05 APR Extras folder at Dropbox. If you would like to help fund the acquisition and preservation of such things, along with getting high quality scans for yourself, please consider signing on either for the APR Patreon or the APR Monthly Historical Documents Program.

Mar 312021

Just released, the March 2021 rewards for APR Patrons and Subscribers. Included this month:

Diagram/art: a large format scan of an artists concept of the XC-14. This was printed with a large number of signatures; they seem to be Boeing engineers.

Document 1: “Project Hummingbird.” An FAA document summarizing the characteristics of STOL and VTOL aircraft circa 1961, including bogh built and proposed types. This was scanned from a clean original!

Document 2: “The Thor Missile Story.” Old, old, incredibly old school media… a film strip propaganda piece about the statues of the Thor IRBM.

CAD diagram: the WWII era German DFS 228 rocket powered high altitude recon plane, proposed operational version.

If this sort of thing is of interest, sign up either for the APR Patreon or the APR Monthly Historical Documents Program.

Because I forgot to mention the January and February rewards… subscribers/patrons got these (new subscribers can order them as back issues):

January 2021: Titan IIIC/IIIM booster rockets; CAD diagram of Post-Saturn concepts; a Convair Heavy Bombardment Airplane brochure; a fractional XF-103 mockup review and technical description; a fractional Westland paper on VTOL; a General Dynamics report on a proposed turboprop transport for Saturn stages.

February, 2021: An Aerion SST brochure; a Lockheed SST diagram; Dornbergers report on a commercial rocket powered airliner (scanned from a clean vintage copy); an early Convair jet flying boat bomber brochure; a CAD diagram comparing General Atomics’ ten-meter Orions for the USAF and NASA.

Can anyone shed any light on this “tanker airplane?”

From the National Archives, a few photos dated 1979 of a Lewis Research Center model of a “Tanker Airplane.” *FAR* higher resolution versions of the photos are available at the links.

TANKER AIRPLANE MODEL

And…

TANKER AIRPLANE MODEL

That’s certainly an unusual configuration. If it hadn’t originated at NASA, I’d think it was a college students design project. But then… there’s one more photo which might shed a little bit of light onto the subject:

TANKER AIRPLANE MODEL

Huh.

The text on the wing reads:

To
LRC from LeRC
November 8(?) 1979

This would seem to be some sort of a gag gift from Lewis Research Center to Langley Research Center, but the details of what, who, and why are not available to me. If anyone can shed light, please do so.

Lockheed NATF

In the long, long ago, Lockheed tried to sell the F-22 to the US Navy. In order to accommodate the needs of Naval aviation, the aircraft would have had to have been massively modified… most obviously by giving the aircraft variable geometry wings like the F-14’s. Clearly the Navy didn’t go for it: the cost of the program would have been immense, as would have been the risks. The F-22 ended up being troubled enough with materials and maintenance nightmares; add to that the rigors of slamming into carrier decks, constant humidity and salt air, all the other bothersome details of operating from ships at sea; and add to THAT the fact that while the NATF (Naval Advanced Tactical Fighter)*looked* like the F-22, it would have shared very few structures in common with its Air Force cousin and would have been basically a new aircraft… it would undoubtedly have been massively expensive to a degree that even the F-35 would have been hard pressed to match.

Mar 012021

APR Patrons and Subscribers today helped crowdfund the purchase of a Boeing blueprint, an inboard profile diagram of the 2707-300 SST. An overly expensive item became reasonably affordable, and will be provided to each of the funders as high resolution scans in full color (and cleaned-up grayscale).

Zenith Star Booster

Feb 272021

This photo has popped up online before, but usually in pretty crummy resolution. It’s taken from “Aerojet – The Creative Company” and shows a mockup for a Titan-derived first stage booster rocket. It has double the engines of the standard Titan core stage, either two or four engines depending on how you want to count the LR-87 engines (one set of turbopumps, two combustion chambers) married to a 15-foot diameter core. This is described as a booster designed to loft the Zenith Star space-based laser weapon test system (the ZS was described and illustrated in US Spacecraft Projects #1). Documentation on this specific booster has always been somewhat lacking, though there have been quite a number of Large Diameter Core Titans designed by Aerojet and Martin over the years.

Home away from home: O’neill colony art

Sigh. It’s sad to think that in many ways the 1970’s were more forward thinking than today. Solar Power Satellites the size of Manhattan, space colonies the size of small states. Today… apart from SpaceX, about the most you can hope for is ever more social media. Until, of course, you get deplatformed.

Below is a piece of NASA-Ames art depicting the interior of an Island 3 colony. The full size version is downloadable HERE. This was intended to be a cylinder 5 miles or so in diameter by 20 long, rotating along the long axis to generate “gravity.” In this design, fully one third of the “land area” was given over to windows that would bring in sunlight via mirrors. Other notions included mounting strips of very powerful artificial light on the “ground” facing up to light the other side (this was the Babylon 5 approach), mounting strips of artificial light along the central axis pointing outwards, having external parabolic mirror beam sunlight through the central axis and reflected or diffused outwards. In order for an island 3 habitat like this to be dynamically stable, you’d need two of them, side by side, rigidly linked at the hubs. This would counter the torque and prevent the cylinders from converting rotation around the long axis into end-over-end tumbling, which is the natural response of something like this (experiment: try to spin a pencils around the long axis. You will inevitably end up with it tumbling)

The NASA art below shows an exterior view of a complete colony.The habitats would need to be pretty close to the same mass, but otherwise their interiors could be very different… one could replicate, say, farmland and meadows and such with small towns scattered about; the other could have forests and large cities. One could be in winter, the other in summer. The full-rez is downloadable HERE.

There is a ring of “cans” around the end of each habitat. These are the agricultural units for the habitat; each independently spin around their own axis, generating the level of artificial G appropriate to grow wheat or corn or weed or hay or whatever is needed. Being smaller in radius, Coriolis effects would be substantially more noticeable; but as plants don’t care, and the job of agriculture will probably be done by robots, it doesn’t matter much. Each farm would be pretty well closed off from the others, so if some sort of blight were to pop up, chances are good it could be contained.

A few years ago I had a notion for a book – half technical descriptions, half manifesto/screed – about megaprojects. A description of not only what mankind could do given time and energy, but what mankind *should* do in time. As with a lot of things, this books got squashed by the realization that its already been done (gosh, thanks Isaac Arthur), but I still kinda want to 3D CAD model one of these things. I’ve not thought about that book in some years… got a hundred pages into it, I think. Shrug.

When the intern just doesn’t care

I’ve found that archives going from pure-paper to digital to be as much a curse as a blessing. Sure, the stuff that gets scanned and placed into publicly accessible archives? Great. But… often enough, archives that scan their stuff often decide that once the original is digitized they have no further use for the original… and it gets thrown away or outright destroyed. that wouldn’t be *too* bad if the scans were good. but too often they’re not. All too often the scans are *crap.* For example, some years back NASA scanned in the files of a deceased engineer. *Lots* of great stuff was scanned and made available. A lot of what the guy had were large format diagrams of hypersonic aircraft… X-24C derivatives, hypersonic research aircraft, HSTs, that sort of thing. What actually got scanned: just the data block. The on-hand scanner was good for letter size, so rather than going to the bother of scanning the large format sheet in chunks, or taking it somewhere than had a large format scanner, whoever did the scanning just scanned, essentially, the title of the thing. And then what? NASA destroyed the originals. You can see the titles, you can see perhaps a piece of a tail or a wingtip… and in all probability that’s all you will *ever* see, because they just couldn’t be bothered.

Recently the “AF FOIA Reading Room” appeared. I’ve found a *few* things of interest on it, one being a summary of the F-108 and B-70 programs. It’s reasonably well illustrated, which is a bonus. Should be great, right? Prepare to be disappointed. Here is the quality of the digitized document… 2-bit black and white at low resolution:

That’s friggen’ craptacular. 2-bit is always the mark of not-giving-a-damn, but to do that with old, clearly time-darkened paper is a crime against humanity. The only way to hope to make anything halfway decent from it is to go through it and manually clean it up. The secondary approach of letting the computer try gives results that are just plain disappointing:

It is *somewhat* clearer. But a whole lot of data is simply lost and unrecoverable, even with manual, skilled and talented cleanup. The “Enhance” button only does so much.

So if *you* have interesting aerospace diagrams and documents, *please* don’t do this. The minimum for text and diagrams is 300 dpi, grayscale, saved in a lossless format such as PNG or TIF. If the diagrams are the slightest bit faded, or if there is anything remotely colorful, scan in full color. Photos and art… full color and consider scanning at 600 or even 1200 dpi. Sure, the file sizes are way bigger. But storage space is vastly cheaper and more abundant than it was just a few years ago. And there are people, AHEM, who will scan this sort of thing for you, just to make sure it’s preserved.

A few seemingly random (because they are) photos. First: a display model of an early General Dynamics concept for what would become the F-111.

And then… two photos of the Convair XB-46 in flight.

I’ve uploaded the full-rez versions of these to the APR Dropbox, into the 2021-01 APR Extras folder. This is available to any APR Patron or Subscriber at the $4 level and above.
