Some years ago I scored some aerospace concept art off ebay. This is not an unusual occurrence; I’ve procured a great many lithographs there. But this one was different… it was the *actual* original painting created in the mid-60’s. At the time I couldn’t really get a good scan of it, but a change in scanners a while back, coupled with the recent move and revival of the “scan everything” project allowed me to finally digitize the thing.

The image depicted a composite aircraft that used stowable rotors for VTOL and hover like a helicopter, and turbofan engines for efficient fast forward speed. As shown here it is operating in Viet Nam in a combat search and rescue role, something the Lockheed CL-945 (a very similar design) was intended for.

The full image is far bigger (a bit bigger than 10X the linear dimensions than the version above) and has been made available as a thank-you to APR Patreon and Historical Documents Program patrons at the above-$10-per-month level. If interested in this piece or if you are interested in helping to fund the preservation of this sort of thing, please consider becoming a patron, either through the APR Patreon or the Monthly Historical Document Program.

As hinted at here and there, I’ve recently moved from rural Utah to non-rural elsewhere. One of the benefits of the move was that it put me a LOT closer to large format scanning services. Previously getting a large blueprint scanned meant several hours on the road and then a return several days later to pick it up; now the drive is a matter of a few minutes. Consequently, my rather extensive backlog of large format aerospace art and diagrams is finally getting scanned in bulk.

Behold some recent results, mostly involving early Titan III, Saturn and Dyna Soar studies:

Some of these will end up in the monthly “catalogs” for the APR patrons to vote on… and some will end up as “extras” for patrons, particularly for above $10-level patrons. If these sort of images are of interest, or if you are interested in helping to fund the preservation of this sort of thing, please consider becoming a patron, either through the APR Patreon or the Monthly Historical Document Program.

Additionally: if you have large format diagrams that you feel are of aerospace historical interest, let me know. I’m always in the market to buy, rent, borrow such things.

In the mad dash to collect what I needed for shipment (and for a time storage… there was, until a late development, the full expectation that I and my cats would spend a good long while as officially homeless), I looked through a great many things I had not examined in a long time, and wound up throwing a *lot*of it into the garbage. My college aerospace engineering homework? Garbage. The vast majority of the photos I took in my pre-digital days? Garbage. This was aided in the fact that the vast majority of those photos had found themselves under a leak in the shop roof and had been welded together into an undifferentiated brick of paper. But a few random, scattered photos were found more or less intact… and even then, most wound up in the garbage because, come on, they were little better than garbage when they were fresh from the developer.

A few that were deemed worthy of scanning were three taken when I was in Space Camp in 1983. The three, which are technically *really* *bad,*  show a Grumman “beam builder” that we space tykes got to see at NASA-Marshall Space Flight Center. A device intended to by launched by the Shuttle, it would be fed rolls of aluminum “tape” and would bend, cut and weld them together into structural beams, sure just the thing that would be needed by the early 90’s at the latest to help build the solar power satellites, space station and early space habitats that would certainly be under construction by then.

As my damn near 40-year-gone memory suggests, we were told that the device on display was a *real* beam builder as opposed to a mockup. But I can’t be sure about that.

I’ve uploaded the three photos scanned at 600 dpi, including some modest “enhancements,” to the 2019-10 APR Extras folder at Dropbox available to all $4 and up APR Monthly Historical Document Program subscribers & Patrons. Is it great stuff? Nope. But what do you really expect from one of these kids?

Continuing…

In 1985 Rockwell gave thought to adding relatively small liquid propellant boosters to the undersides of the Orbiters wings. Even though the boosters were relatively small, with only a single RL-10 engine fed from low-density, narrow-diameter liquid hydrogen tanks. Even so, Rockwell projected an additional 15,000 pounds of payload. This would seem to require some interesting modifications to the underside of the wings… not just adding mounting hardpoints, but doors that could close over them after the boosters are jettisoned.

Continuing. This time, discussion of possibilities of swapping out existing Orbiter structures with graphite composites. The advantage would be lowered dry mass of the Orbiter, leading to potentially higher payload performance. this would, presumably, be of interest for USAF launches from Vandenburg, a possibility that Challenger put to bed.

If this sort of stuff is of interest or use, why not help support the project? A monthly subscription to the APR Monthly Historical Documents Program would not only help support the project, it would also provide you with a monthly package of rare aerospace documents and diagrams.

Around three years ago I posted some rather cruddy images of a saucer-shaped nuclear-powered spacecraft that the Chrysler corporation drew up in 1956. At this time a manned spacecraft was a perfectly normal sort of thing for Chrysler to design; their aerospace division was responsible for the Redstone missile and the Saturn I first stage. One of the images was a small scan of the cover of the August-September 1957 issue of “Saucer News.” I finally managed to score a copy of this “fanzine”on ebay a while back and have scanned the cover at high (600 dpi) resolution. The image quality is a bit regrettable, but what can you expect from a 1950’s UFO magazine.

As always, if anyone might happen to know anything more about this design, I’m all ears. Chrysler long ago got rid of their aerospace division and whatever archive it might have had.

I have uploaded the full resolution scan to the 2019-08 APR Extras Dropbox folder, available to $4 and up subscribers to the APR Monthly Historical Documents Program.

McDonnell Douglas spent much of the 1970’s  trying to get NASA, the Marines and the Navy to fund the development of a lift-fan-based VTOL aircraft concept, the Model 260. This general concept showed up in a number of different forms, from strike bomber to carrier onboard delivery transport to Marine troop transport. Shown below is a”Research Technology Aircraft,” a proof of concept prototype to be assembled from existing aircraft components, much as Rockwell did with the XFV-12.

I’ve made the full resolution version of the diagram (equivalent to 37 inches wide at 300dpi) available to above-$10-subscribers of the APR Monthly Historical Documents Program/Patreon.

If this sort of thing is of interest, consider subscribing. Even a buck a month will help out; but the more you subscribe for, the more you get… and the more you help me get from eBay and save for the ages.

For much of the time while the concept of the Space Shuttle was being developed the vehicle consisted of a manned flyback booster of relatively enormous dimensions, coupled with an orbiter that included sizable internal oxygen tanks, sometimes with external hydrogen tanks, sometimes internal. The model below, a masterpiece of late 1960’s model makers craft, illustrates one such concept. the orbiter is similar to the Grumman H-33 except larger, with completely internal hydrogen and oxygen tanks.

Had this type of Space Shuttle been built and flown successfully, there is every chance that it would have been substantially less costly to operate than the Shuttle we got: flying the booster back to a runway landing and refurbishing it would theoretically have been a lot faster and easier than fishing solid rocket motor casings out of the ocean and shipping them to Utah for refurb. But getting the design to the point of operation would have been a nightmare. The booster was unlike anything previously attempted, and would have been an aircraft roughly the size of the C-5 Galaxy, with a top speed like that of the X-15

 

I have uploaded the full resolution scan of the photo to the 2019-07 APR Extras Dropbox folder, available to $4 and up subscribers to the APR Monthly Historical Documents Program.
