Every month, patrons of the Aerospace Projects Review Patreon campaign are rewarded with a bundle of documents and diagrams, items of interest and importance to aerospace history. If you sign up, you get the monthly rewards going forwards; the “back issues” catalog lets patrons aid the APR cause by picking up items from before they signed on. The catalog, available to all patrons at the APR Patreon, has been updated to include everything from the beginning of the project back in 2014 on up to February, 2017.

Below are the items from 2016 (and the first two months of 2017):

 

If you are interested in any of these and in helping to fund the mission of Aerospace Projects Review, drop by the APR Patreon page and sign up. For only a few bucks a month you can help fund the procurement, scanning and dissemination of interesting aerospace documentation that might otherwise vanish from the public.

Now available: two new US Aerospace Projects issues. Cover art was provided by Rob Parthoens, www.baroba.be

US Bomber Projects #19

US Bomber Projects #19 is now available (see HERE for the entire series). Issue #19 includes:

  • Early Atlas Concept: Parallel Staged Missile: three-bodied concept leading to the Atlas ICBM
  • Lockheed L-286-665: A supersonic nuclear powered design
  • Consolidated XA-44 Model 112: a three-engined forward-swept jet
  • Convair Pilotless Airplane I-40: a TV & radar guided missile
  • Martin Model 151-J: A late pre-war design
  • Boeing Model 464-79-0: a long-span B-52 with floating wingtips
  • Lockheed-Martin VS-07: A recent stealthy variable geometry concept
  • Boeing Model 724-15: Boeings first giant competitor for the B-70

 

USBP #19 can be downloaded as a PDF file for only $4.25:

  • Bell Rocket Fighter: A design similar to the X-1
  • North American RD-1381-B: A two-stage VTO design
  • Boeing Model 457: A rocket boosted ramjet fighter with two stages
  • Truax Rocket Fighter: A VTO ship-launched interceptor
  • Northrop XP-79: A flying wing with a prone pilot
  • Lockheed CL-362-1: A late 1950’s spaceplane-like hypersonic concept

If there was ever a demonstration of the combination of “technical genius” with “wartime desperation,” it was the Bachem Natter from late in World War II. This German design was a point defense interceptor, from a time when B-17’s, B-24’s and Lancasters freely roamed the sky, laying waste to the German infrastructure. The Natter was a rocket-powered, vertical takeoff, partially reusable manned surface-to-air missile. It was to be armed with a multitude of unguided explosive-tipped rockets in the nose, probably to be launched as a single salvo. Reportedly, someone had the bright idea that the pilot would then aim his plane at another bomber for a ramming attack, bailing out at the last second. But since bailing out meant separating the nose from just forward of the cockpit aft bulkhead, the likelihood is vanishingly low that either the pilot would survive or that the Natter would continue forward in a predictable path. The more reasonable approach would still be for the pilot to bail out, but for both the pilot and the aircraft to pop chute and land safe enough to be recovered and reused.

The Natter was launched unmanned a few times and manned once, killing the pilot. It was *kind* of a neat idea, but the execution was not so good. The Germans would have been better advised to have worked on unmanned surface to air missiles than the Natter. But for all the claims of vaunted German efficiency, the Nazi regime was astonishingly inefficient, with many redundant and non-communicative programs.

Just as well, in retrospect.

There are many photos and illustrations of the Natter out there, but I figured these diagrams might be of interest.

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…

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.

A meeting of giants at Edwards Air Force Base in the late 1960’s. It’s interesting to compare the size of the “fighter” with the “bomber…” the bomber, as anyone who has ever stood underneath the sole example in Dayton, is Really Big, but the YF-12 is just not that much smaller. Sustained Mach 3 flight is not for the faint hearted… or the small-engined or those with dainty fuel tanks.

I have made the full-rez version of this photo available for APR Patrons at the $4 level and up in the 2017-01 folder of the APR Extras Dropbox site. If interested in getting this and the previous years worth of Extras, consider signing up for the APR Patreon.

This video has it all:

  1. Unbuilt aircraft concept
  2. Scale model (wind tunnel model) construction
  3. Cyanotype Blueprints
  4. Complete lack of an audio track

The obvious question that this video raises is… what happened with the model? Most wind tunnel models end up getting scrapped – shredded and melted down to recycle the metal. but every now and then one escapes. The company keeps it for display, or in an archive, or sometimes an employee simply takes it home. Sometimes they end up on EBay.

I’ve been running the Aerospace Projects Review Patreon project for a bit over two years now. Every month, Patrons get rewarded with sets of aerospace history stuff… currently, one large-format diagram or piece of artwork, three documents and, depending on level of patronage, an all-new CAD diagram of an aerospace subject of interest. More than two dozen such packages have been put together so far and distributed. Given that you can get in on this for as little as $1.50 a month (for 125-dpi scans… $4/month for full-rez 300 dpi scans) and you get at least four items, that’s a pretty good bargain compared to the individual aerospace drawings and documents.

Patrons who signed up after the process got underway can now get “back issues” of the previously released rewards packages. A catalog of more than the first years worth has just been posted; each month will see an updated catalog posted for Patrons to order from. So if you are interested, check out the APR Patreon page to see how to sign up; if you are already a patron, check out the catalog here.

A heavily illustrated USAF brochure on turbine engine technology included, among a vast number of little photos of engines and aircraft, a few illustrations that might be of interest.

Several futuristic concepts here, several old ones. Of particular interest is the “Supersonic Multirole Fighter,” which looks like a cross between the old Lockheed Hopeless Diamond concept and the Northrop XST design… tailless with an inlet on top, with features reminiscent of the F-117, but blended rather than faceted.

Of these “Emerging Concept Needs,” several are distinctly old. The middle row of three designs are all 20+ year-old concepts.

This one is new to me… apparently the Germans used standard railway tracks and RATO-bottle-boosted sleds to launch replica Messerschmitt Me 163’s, with variable success. Given the fuel-hoggishness of the rocket plane, anything that would get them up to speed and into the air quickly would seem to be an advantage.
